Here we show that in zebrafish, the geometry of the fertilized egg—specifically its curvature and volume—serves as a critical initial condition triggering a cascade of events that influence development. The embryo geometry guides patterned asymmetric cell divisions in the blastoderm, generating radial gradients of cell volume and nucleocytoplasmic ratio. These gradients generate mitotic phase waves, with the nucleocytoplasmic ratio determining individual cell cycle periods independently of other cells. We demonstrate that reducing cell autonomy reshapes these waves, emphasizing the instructive role of geometry-derived volume patterns in setting the intrinsic period of the cell cycle oscillator. In addition to organizing cell cycles, early embryo geometry spatially patterns zygotic genome activation at the midblastula transition, a key step in establishing embryonic autonomy. Disrupting the embryo shape alters the zygotic genome activation pattern and causes ectopic germ layer specification, underscoring the developmental significance of geometry. Together, our findings reveal a symmetry-breaking function of early embryo geometry in coordinating cell cycle and transcriptional patterning.","lang":"eng"}],"OA_type":"hybrid","OA_place":"publisher","oa":1,"file_date_updated":"2026-01-21T08:21:11Z","title":"Geometry-driven asymmetric cell divisions pattern cell cycles and zygotic genome activation in the zebrafish embryo","publication_identifier":{"eissn":["1745-2481"],"issn":["1745-2473"],"issnl":[" 1745-2473"]},"volume":22,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"doi":"10.1038/s41567-025-03122-1","date_published":"2026-01-05T00:00:00Z","_id":"21015","date_updated":"2026-04-28T12:55:30Z","status":"public","related_material":{"link":[{"url":"https://ista.ac.at/en/news/geometry-shapes-life/","description":"News on ISTA website","relation":"research_data"}]},"type":"journal_article","PlanS_conform":"1","citation":{"chicago":"Mishra, Nikhil, Yuting I Li, Edouard B Hannezo, and Carl-Philipp J Heisenberg. “Geometry-Driven Asymmetric Cell Divisions Pattern Cell Cycles and Zygotic Genome Activation in the Zebrafish Embryo.” <i>Nature Physics</i>.

Here, we report the discovery and characterization of abundant extracellular vesicles (EVs) in planarians. Using imaging and molecular analysis, we show conservation of biogenesis, morphology, and protein composition of planarian EVs. Environmental stressors significantly elevate EV release, indicating that planarians dynamically regulate vesicle production. Functionally, planarian EVs mediate intercellular communication by transferring regulatory signals: We find that they shuttle small RNAs that effect systemic RNA interference (RNAi) throughout the organism. Notably, gene knockdown experiments reveal a crucial role for AGO-3, a member of the Argonaute family of proteins, in modulating the association of small interfering RNAs with EVs, linking the intracellular RNAi machinery to EV-based signaling. These findings highlight EVs as pivotal mediators of cell-cell communication in planarians, with broad implications for understanding the coordination of gene regulation and tissue regeneration in animals."}],"date_published":"2026-02-01T00:00:00Z","tmp":{"image":"/images/cc_by_nc.png","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","short":"CC BY-NC (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode"},"doi":"10.1126/sciadv.ady1461","_id":"21383","date_updated":"2026-03-02T14:23:22Z","type":"journal_article","status":"public","volume":12,"issue":"6","article_number":"eady1461","oa_version":"Published Version","article_processing_charge":"Yes","fulldoi":"https://doi.org/10.1126/sciadv.ady1461","quality_controlled":"1","month":"02","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2026-03-02T10:08:07Z","license":"https://creativecommons.org/licenses/by-nc/4.0/","author":[{"full_name":"Sasidharan, Vidyanand","first_name":"Vidyanand","last_name":"Sasidharan"},{"last_name":"Ancellotti","full_name":"Ancellotti, Laura","first_name":"Laura"},{"first_name":"Viraj","full_name":"Doddihal, Viraj","last_name":"Doddihal","id":"034e0824-174b-11ef-b32b-9366a0e70d1c"},{"last_name":"Brewster","full_name":"Brewster, Carolyn","first_name":"Carolyn"},{"last_name":"Mann","first_name":"Frederick","full_name":"Mann, Frederick"},{"full_name":"McKinney, Mary Cathleen","first_name":"Mary Cathleen","last_name":"McKinney"},{"last_name":"Varberg","full_name":"Varberg, Joseph","first_name":"Joseph"},{"last_name":"Ross","first_name":"Eric","full_name":"Ross, Eric"},{"first_name":"Fengyan","full_name":"Deng, Fengyan","last_name":"Deng"},{"first_name":"Kexi","full_name":"Yi, Kexi","last_name":"Yi"},{"first_name":"Alejandro","full_name":"Sánchez Alvarado, Alejandro","last_name":"Sánchez Alvarado"}],"has_accepted_license":"1","acknowledgement":"We thank all the Sánchez Alvarado lab members for inputs and discussions.

While Rheo-FLUCS is facilitated by thermoviscous expansion phenomena rather than external forces, here we show equivalence in its ability to measure relative viscoelastic properties. Specifically, we demonstrate a phase-lag equivalence with probe-dependent active microrheology in a wide range of physically different, yet chemically identical materials. We exemplify the utility of Rheo-FLUCS in three distinctly different biological systems: compound-treated mouse fibroblasts (NIH-3T3), genetically modified human osteoblasts (U2OS) to elucidate the role of myosins in cytoplasmic mechanics, and early ascidian oocytes of Phallusia mammillata at fertilization stage.

During zebrafish embryogenesis, the enveloping layer (EVL) – an epithelial monolayer covering the blastoderm – undergoes extensive spreading that is driven by pulling forces exerted at its margin and more than doubles its surface area. Yet whether and how the EVL actively regulates its tissue tension during this process remains unclear. Here, we show that the EVL maintains constant tissue tension while spreading, and that it achieves this by reducing apical cell contractility in response to the same pulling forces that drive its spreading. We identify a mechanosensitive pathway underlying this response, mediated by the scaffold/adaptor protein Kibra regulating the activity of atypical protein kinase C (aPKC) at the apical domain of EVL cells. Under low mechanical stretch, Kibra forms condensates at the base of actin-based apical projections, where it activates Myosin II to increase apical contractility through aPKC downregulation. As mechanical stretch increases, apical projections disassemble, Kibra condensates dissolve, and aPKC activity rises. Elevated aPKC activity in turn reduces apical contractility by reducing Myosin II activity, thereby maintaining constant tissue tension despite increased mechanical stretch. Together, these findings reveal a mechanosensitive mechanism that enables robust adaptation of tissue tension to changing mechanical stretch, ensuring efficient tissue spreading and morphogenesis."}],"OA_place":"publisher","OA_type":"green","oa":1,"title":"Apical domain mechanosensation regulates tissue tension homeostasis","file_date_updated":"2026-07-13T09:16:28Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"date_published":"2026-07-14T00:00:00Z","_id":"22276","date_updated":"2026-07-14T07:07:41Z","related_material":{"record":[{"relation":"earlier_version","id":"21864","status":"public"}]},"status":"public","type":"preprint","researchdata_availability":"yes","citation":{"apa":"Hino, N., Kapoor, T., Gubbala, U.

How spreading tissues balance flexibility with integrity is not yet well understood. Here, we show that keratin intermediate filaments adapt tissue mechanical resilience to the stresses arising in epithelial tissues during spreading. By analyzing the expansion of the enveloping cell layer (EVL) over the yolk cell in zebrafish embryos in vivo, we find that keratin network maturation in EVL cells is promoted by stresses building up within the spreading tissue. Through genetic interference and tissue rheology experiments, complemented by a vertex model with mechanochemical feedback, we demonstrate that stress-induced keratin network maturation in the EVL increases tissue viscosity, to prevent tissue rupture. Further, keratins are required in the yolk cell for mechanosensitive actomyosin network contraction and flow, the forces pulling the EVL. These dual mechanosensitive functions of keratins enable a balance between pulling force production and EVL mechanical resilience, ensuring uniform and robust tissue spreading.","lang":"eng"}],"external_id":{"pmid":["42143048"]},"related_material":{"record":[{"relation":"earlier_version","status":"public","id":"20465"}]},"status":"public","type":"journal_article","date_updated":"2026-07-29T10:33:31Z","_id":"22608","doi":"10.1038/s41467-026-72366-z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"date_published":"2026-07-17T00:00:00Z","article_number":"6499","volume":17,"intvolume":"        17","das_tickbox":"1","file":[{"content_type":"application/pdf","relation":"main_file","file_size":15363936,"creator":"dernst","success":1,"checksum":"f26d96e180c1d034d9c9c8f57c3c258b","file_id":"22609","file_name":"2026_NatureComm_Naik.pdf","date_updated":"2026-07-29T10:27:25Z","date_created":"2026-07-29T10:27:25Z","access_level":"open_access"}],"citation":{"apa":"Naik, S., Keta, Y.-E., Pranjic-Ferscha, K., Hannezo, E.

It lays the foundation for subsequent developmental events, including gastrulation, germ layer specification, organogenesis, and the establishment of the overall body plan. Two major modes of cleavage exist in the animal kingdom: holoblastic (complete) and meroblastic (incomplete) cleavage. Because holoblastic cleavage resembles canonical cytokinesis, its biochemical and mechanical basis has been extensively studied — an annular contractile ring forms at the equator and constricts in a purse-string-like manner, leading to the complete separation of two daughter cells. In contrast, although meroblastic cleavage occurs widely across the animal kingdom (e.g. in fish, reptiles, birds, and cephalopod molluscs), its mechanical basis remains largely unclear. During meroblastic cleavage, the cytokinetic furrow forms only at one pole and does not traverse the entire embryo, raising the question of how cytokinesis proceeds in the absence of a closed contractile ring. Moreover, the resulting daughter cells are not fully separated from the underlying yolk compartment, and how these blastomeres are subsequently cellularised remains unknown. This thesis takes the zebrafish as a model organism to address both questions. The first part characterises the biochemical and mechanical mechanisms underlying non-canonical meroblastic cleavage, revealing a two-phase process in which actomyosin cable contraction and cadherin-mediated membrane adhesion act sequentially to drive furrow ingression and invagination. The second part sheds light on the spatiotemporal dynamics by which individual blastomeres become cellularised, and uncovers a previously unrecognised contribution of central blastomeres to the yolk syncytial layer."}],"oa":1,"title":"Towards a deeper understanding of meroblastic cleavage","file_date_updated":"2026-09-14T12:48:53Z","publication_identifier":{"issn":["2663-337X"],"isbn":["978-3-99078-080-0"]},"OA_place":"publisher","year":"2026","researchdata_availability":"upon request","citation":{"chicago":"Tong, Xin. “Towards a Deeper Understanding of Meroblastic Cleavage.” Institute of Science and Technology Austria, 2026. <a href=\"https://doi.org/10.15479/AT-ISTA-22804\">https://doi.org/10.15479/AT-ISTA-22804</a>.","mla":"Tong, Xin. <i>Towards a Deeper Understanding of Meroblastic Cleavage</i>.

Most studies in vivo have focused on the migration of cells using the extracellular matrix (ECM) as their substrate for migration. In contrast, much less is known about how cells migrate on other cells, as found in early embryos when the ECM has not yet formed. Here, we show that lateral mesendoderm (LME) cells in the early zebrafish gastrula use the ectoderm as their substrate for migration. We show that the lateral ectoderm is permissive for the animal-pole-directed migration of LME cells, while the ectoderm at the animal pole halts it. These differences in permissiveness depend on the lateral ectoderm being more cohesive than the animal ectoderm, a property controlled by bone morphogenetic protein (BMP) signaling within the ectoderm. Collectively, these findings identify ectoderm tissue cohesion as one critical factor in regulating LME migration during zebrafish gastrulation."}],"external_id":{"isi":["001443652700001"],"pmid":["40057955"]},"_id":"19404","tmp":{"short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"},"doi":"10.1016/j.celrep.2025.115387","date_published":"2025-03-25T00:00:00Z","status":"public","type":"journal_article","date_updated":"2025-10-22T07:00:04Z","volume":44,"article_number":"115387","issue":"3","DOAJ_listed":"1","file":[{"success":1,"file_id":"19413","file_name":"2025_CellReports_Tavano.pdf","checksum":"57e05dd1598c807af0afdb32cec039d3","date_created":"2025-03-17T10:26:54Z","access_level":"open_access","date_updated":"2025-03-17T10:26:54Z","relation":"main_file","content_type":"application/pdf","file_size":9067797,"creator":"dernst"}],"intvolume":"        44","citation":{"mla":"Tavano, Ste, et al. “BMP-Dependent Patterning of Ectoderm Tissue Material Properties Modulates Lateral Mesendoderm Cell Migration during Early Zebrafish Gastrulation.” <i>Cell Reports</i>, vol. 44, no. 3, 115387, Elsevier, 2025, doi:<a href=\"https://doi.org/10.1016/j.celrep.2025.115387\">10.1016/j.celrep.2025.115387</a>.","ama":"Tavano S, Brückner D, Tasciyan S, et al.

Using super-resolution microscopy, we analysed the segregation of organelles during the division of the neuroblast QL.p in C. elegans larvae. QL.p divides to generate a daughter that survives, QL.pa, and a daughter that dies, QL.pp. We found that mitochondria segregate unequally by density and morphology and that this is dependent on mitochondrial dynamics. Furthermore, we found that mitochondrial density in QL.pp correlates with the time it takes QL.pp to die. We propose that low mitochondrial density in QL.pp promotes the cell death fate and ensures that QL.pp dies in a highly reproducible and timely manner.

However, the molecular mechanisms integrating front-to-rear information into this intercellular signaling cascade, particularly the determinants of cellular front-side specification, remain elusive. We visualized the activity of EGFR, Ras, Rac1 and Rab5A (hereafter Rab5) by using FRET biosensors and chemogenetic tools. Whereas EGFR activation was uniformly observed within cells, Ras activation was biased to the front side within cells. The polarized Ras activation depended on Merlin and Rac1, which also showed front-biased activation. Furthermore, Rab5, a crucial regulator of cell migration, demonstrated similar front-biased activation and was found to function downstream of Ras while being necessary for Rac1 activation. Thus, the positive feedback loop consisting of Ras, Rab5 and Rac1 is activated primarily at the front of collectively migrating cells. These findings offer new spatio-temporal insight into processing front–rear information during collective cell migration."}],"external_id":{"pmid":["40667649"],"isi":["001567723900009"]},"_id":"20188","doi":"10.1242/jcs.263779","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"date_published":"2025-08-01T00:00:00Z","status":"public","type":"journal_article","date_updated":"2025-11-27T14:12:24Z","volume":138,"article_number":"263779","issue":"15","file":[{"date_updated":"2025-09-01T10:02:24Z","access_level":"open_access","date_created":"2025-09-01T10:02:24Z","checksum":"29f42619dab5ce251a20c769ed4581c0","file_name":"2025_JourCellScience_Jikko.pdf","file_id":"20262","success":1,"creator":"dernst","file_size":12393297,"content_type":"application/pdf","relation":"main_file"}],"intvolume":"       138","citation":{"mla":"Jikko, Yuya, et al. “Front-Biased Activation of the Ras-Rab5-Rac1 Loop Coordinates Collective Cell Migration.” <i>Journal of Cell Science</i>, vol. 138, no. 15, 263779, The Company of Biologists, 2025, doi:<a href=\"https://doi.org/10.1242/jcs.263779\">10.1242/jcs.263779</a>.","ama":"Jikko Y, Deguchi E, Matsuda K, et al.

Epiboly requires the transition of the epithelium\r\nwith cuboidal cells to form a thin, flat squamous epithelial sheet. During this transition, the\r\ncells show tissue-scale mechanosensation with mechanisms such as direct mechanical control\r\nover the axis of cell division.\r\nCytoskeletal intermediate filaments play a crucial role in vertebrate cells, not only facilitating\r\nmechanical stability but also helping facilitate the mechanosensitive response of the cell.\r\nMechanosenstivity displayed by intermediate filaments is due not just to their interesting\r\nphysical properties but also to their interactions with other cytoskeletal elements such as actin\r\nand microtubules. Keratin is the predominant intermediate filament expressed in the EVL.\r\nIt expresses concomitantly with the gastrulation movements of the developing embryo. Our\r\nwork focuses on understanding the role and dynamics of the keratin cytoskeletal network in\r\nmodulating the physical aspects of EVL spreading. We demonstrated with the combination of\r\nphysical characterisation and manipulations of the EVL, utilising a variety of biophysical tools\r\nand microscopy, the mechanistic role of keratin in tissue spreading.\r\nGenerating novel genetic morphants and mutants, we probe the effect that the loss of the\r\nkeratin network has on the physiology of the epithelium and the developing embryo. We\r\nshow that the changing organisation of the keratin network is important for changing EVL\r\nphysical properties as the stress imposed on the EVL increases during epiboly. By modelling\r\nthe epithelium, we study how the mechanical heterogeneity in an epithelium can feed back into\r\na mechanical loop to the maturation of the keratin network and hence affect the mechanics\r\nof the epithelium. However, unlike what would be predicted by the effect of intermediate\r\nfilaments in acting as a security belt and increasing the resistance of the epithelium, we observe\r\nthat loss of keratin leads to a delay in the EVL movement. Using both local aspirations of the\r\nYSL and EVL ablations, we demonstrate the mechanistic facilitation of actin mechanosensation\r\nin a keratin-dependent manner.\r\nFurthermore, using chemical inhibitors of microtubule polymerisation, we provide insight into\r\nthe mechanisms underlying the organisation and distribution of keratin. Interestingly, the\r\nphenotype observed upon this loss of microtubules shows that keratins interact with the nucleus\r\nthrough microtubular interactions. Together with these diverse observations, we describe\r\nthe mechanosensory feedback between resilience and that is critical for uniform and robust\r\nspreading of the epithelium.","lang":"eng"}],"OA_place":"publisher","oa":1,"file_date_updated":"2025-10-28T13:10:26Z","publication_identifier":{"isbn":["978-3-99078-069-5"],"issn":["2663-337X"]},"title":"Keratins act as global coordinators of tissue spreading through mechanosensitive feedback","year":"2025","citation":{"chicago":"Naik, Suyash. “Keratins Act as Global Coordinators of Tissue Spreading through Mechanosensitive Feedback.” Institute of Science and Technology Austria, 2025. <a href=\"https://doi.org/10.15479/AT-ISTA-20441\">https://doi.org/10.15479/AT-ISTA-20441</a>.","mla":"Naik, Suyash. <i>Keratins Act as Global Coordinators of Tissue Spreading through Mechanosensitive Feedback</i>.

How these opposing requirements are balanced within spreading tissues is not yet well understood. Here, we show that keratin intermediate filaments function in epithelial spreading by adapting tissue mechanical resilience to the stresses arising in the tissue during the spreading process. By analysing the expansion of the enveloping cell layer (EVL) over the large yolk cell in early zebrafish embryos in vivo, we found that keratin network maturation in EVL cells is promoted by stresses building up within the spreading tissue. Through genetic interference and tissue rheology experiments, complemented by a vertex model with mechanochemical feedback, we demonstrate that stress-induced keratin network maturation in the EVL increases tissue viscosity, which is essential for preventing tissue rupture. Interestingly, keratins are also required in the yolk cell for mechanosensitive actomyosin network contraction and flow, the force-generating processes pulling the EVL. These dual mechanosensitive functions of keratins enable a balance between pulling force production in the yolk cell and the mechanical resilience of the EVL against stresses generated by these pulling forces, thereby ensuring uniform and robust tissue spreading.","lang":"eng"}],"department":[{"_id":"CaHe"},{"_id":"EdHa"}],"day":"17","license":"https://creativecommons.org/licenses/by-nd/4.0/","date_created":"2025-10-14T07:25:27Z","corr_author":"1","author":[{"first_name":"Suyash","full_name":"Naik, Suyash","id":"2C0B105C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8421-5508","last_name":"Naik"},{"first_name":"Yann-Edwin","full_name":"Keta, Yann-Edwin","last_name":"Keta"},{"last_name":"Pranjic-Ferscha","id":"4362B3C2-F248-11E8-B48F-1D18A9856A87","first_name":"Kornelija","full_name":"Pranjic-Ferscha, Kornelija"},{"orcid":"0000-0001-6005-1561","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","last_name":"Hannezo","first_name":"Edouard B","full_name":"Hannezo, Edouard B"},{"full_name":"Henkes, Silke","first_name":"Silke","last_name":"Henkes"},{"full_name":"Heisenberg, Carl-Philipp J","first_name":"Carl-Philipp J","last_name":"Heisenberg","id":"39427864-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0912-4566"}],"year":"2025","fulldoi":"https://doi.org/10.1101/2025.02.14.638262","month":"02","das_tickbox":"1","article_processing_charge":"No","oa_version":"Preprint","main_file_link":[{"url":"https://doi.org/10.1101/2025.02.14.638262","open_access":"1"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ama":"Naik S, Keta Y-E, Pranjic-Ferscha K, Hannezo EB, Henkes S, Heisenberg C-PJ.

Yet how the temporal and spatial regulations of cell behaviors are interconnected during embryonic development remains elusive. To address this, we turned to zebrafish gastrulation, the process whereby dynamic cell behaviors generate the three principal germ layers of the early embryo. Here, we show that Hoxb cluster genes are expressed in a temporally collinear manner at the blastoderm margin, where mesodermal and endodermal (mesendoderm) progenitor cells are specified and ingress to form mesendoderm/hypoblast. Functional analysis shows that these Hoxb genes regulate the timing of cell ingression: under- or overexpression of Hoxb genes perturb the timing of mesendoderm cell ingression and, consequently, the positioning of these cells along the forming anterior-posterior body axis after gastrulation. Finally, we found that Hoxb genes control the timing of mesendoderm ingression by regulating cellular bleb formation and cell surface fluctuations in the ingressing cells. Collectively, our findings suggest that Hoxb genes interconnect the temporal and spatial pattern of cell behaviors during zebrafish gastrulation by controlling cell surface fluctuations."}],"external_id":{"isi":["001525252300001"],"pmid":["40576478"]},"OA_type":"hybrid","OA_place":"publisher","file_date_updated":"2025-07-23T08:43:01Z","publication_identifier":{"eissn":["1477-9129"],"issn":["0950-1991"]},"title":"Hoxb genes determine the timing of cell ingression by regulating cell surface fluctuations during zebrafish gastrulation","oa":1,"year":"2025","citation":{"apa":"Moriyama, Y., Mitsui, T., &#38; Heisenberg, C.-P.

Across animals, two principal modes exist: complete (holoblastic) and incomplete (meroblastic) cleavage. While holoblastic cleavage resembles conventional cytokinesis both in vitro and in vivo, the mechanisms underlying meroblastic cleavage have remained poorly understood. Using zebrafish embryos as a model, we show that meroblastic cleavage proceeds through a distinct two-step mechanism. The process begins with the assembly and contraction of a large, arc-shaped actomyosin cable. However, this contractile event alone is insufficient to complete division. A second phase, driven by cadherin-mediated membrane adhesion, is required to invaginate the furrow ridge. Strikingly, this transition depends on mechanical uncoupling of the contractile cable from the surrounding cortex. We demonstrate that such uncoupling arises from an active nematic instability, which both enhances contractility along the cable and generates actin depletion zones that relieve lateral connections. Together, these findings reveal that meroblastic cleavage is governed not by a single actomyosin-based event but by a sequential interplay between cytoskeletal contraction and cadherin-dependent adhesion, highlighting a mechanism fundamentally distinct from canonical cytokinesis."}],"external_id":{"biorxivid":["2025.10.15.682552"]}},{"file":[{"creator":"dernst","relation":"main_file","content_type":"application/pdf","file_size":5195262,"file_name":"2024_DevelopmentalCell_Hoermayer.pdf","file_id":"17452","checksum":"22b374fb50a40d380b7686c84258d271","access_level":"open_access","date_created":"2024-08-20T11:22:16Z","date_updated":"2024-08-20T11:22:16Z","success":1}],"ec_funded":1,"intvolume":"        59","citation":{"ieee":"L.

Nonetheless, the mechanism(s) determining division plane orientation remain elusive. Here, we studied tissue healing after laser-assisted wounding in roots of Arabidopsis thaliana and uncovered how mechanical forces stabilize and reorient the microtubule cytoskeleton for the orientation of cell division. We identified that root tissue functions as an interconnected cell matrix, with a radial gradient of tissue extendibility causing predictable tissue deformation after wounding. This deformation causes instant redirection of expansion in the surrounding cells and reorientation of microtubule arrays, ultimately predicting cell division orientation. Microtubules are destabilized under low tension, whereas stretching of cells, either through wounding or external aspiration, immediately induces their polymerization. The higher microtubule abundance in the stretched cell parts leads to the reorientation of microtubule arrays and, ultimately, informs cell division planes. This provides a long-sought mechanism for flexible re-arrangement of cell divisions by mechanical forces for tissue reconstruction and plant architecture."}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"doi":"10.1016/j.devcel.2024.03.009","date_published":"2024-05-20T00:00:00Z","_id":"15301","date_updated":"2025-09-04T13:32:08Z","status":"public","related_material":{"link":[{"description":"News on ISTA website","url":"https://ista.ac.at/en/news/how-plants-heal-wounds/","relation":"press_release"}]},"type":"journal_article","volume":59,"issue":"10","oa_version":"Published Version","article_processing_charge":"Yes (via OA deal)","fulldoi":"https://doi.org/10.1016/j.devcel.2024.03.009","month":"05","quality_controlled":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","corr_author":"1","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"page":"1333-1344.e4","date_created":"2024-04-08T12:07:57Z","author":[{"orcid":"0000-0001-8295-2926","last_name":"Hörmayer","id":"2EEE7A2A-F248-11E8-B48F-1D18A9856A87","full_name":"Hörmayer, Lukas","first_name":"Lukas"},{"last_name":"Montesinos López","id":"310A8E3E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9179-6099","first_name":"Juan C","full_name":"Montesinos López, Juan C"},{"last_name":"Trozzi","first_name":"N","full_name":"Trozzi, N"},{"last_name":"Spona","id":"b52391fb-f636-11ee-939c-8a8c47552e8a","first_name":"Leonhard","full_name":"Spona, Leonhard"},{"full_name":"Yoshida, Saiko","first_name":"Saiko","id":"2E46069C-F248-11E8-B48F-1D18A9856A87","last_name":"Yoshida"},{"id":"44E59624-F248-11E8-B48F-1D18A9856A87","last_name":"Marhavá","full_name":"Marhavá, Petra","first_name":"Petra"},{"orcid":"0000-0002-5223-3346","id":"2F1E1758-F248-11E8-B48F-1D18A9856A87","last_name":"Caballero Mancebo","full_name":"Caballero Mancebo, Silvia","first_name":"Silvia"},{"id":"38F4F166-F248-11E8-B48F-1D18A9856A87","last_name":"Benková","orcid":"0000-0002-8510-9739","full_name":"Benková, Eva","first_name":"Eva"},{"first_name":"Carl-Philipp J","full_name":"Heisenberg, Carl-Philipp J","last_name":"Heisenberg","id":"39427864-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0912-4566"},{"last_name":"Dagdas","first_name":"Y","full_name":"Dagdas, Y"},{"full_name":"Majda, M","first_name":"M","last_name":"Majda"},{"full_name":"Friml, Jiří","first_name":"Jiří","last_name":"Friml","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87"}],"has_accepted_license":"1","project":[{"call_identifier":"H2020","grant_number":"742985","name":"Tracing Evolution of Auxin Transport and Polarity in Plants","_id":"261099A6-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","grant_number":"P29988","name":"RNA-directed DNA methylation in plant development","_id":"262EF96E-B435-11E9-9278-68D0E5697425"}],"isi":1,"acknowledgement":"We are thankful to Simon Gilroy, Alexander Jones, and Lieven De Veylder for sharing published material.

However, how these cortical flows interact with adjacent cytoplasmic components, changing their form and localization, and how this affects cytoplasmic organization and cell shape remains unclear. Here we show that in ascidian oocytes, the cooperative activities of cortical actomyosin flows and deformation of the adjacent mitochondria-rich myoplasm drive oocyte cytoplasmic reorganization and shape changes following fertilization. We show that vegetal-directed cortical actomyosin flows, established upon oocyte fertilization, lead to both the accumulation of cortical actin at the vegetal pole of the zygote and compression and local buckling of the adjacent elastic solid-like myoplasm layer due to friction forces generated at their interface. Once cortical flows have ceased, the multiple myoplasm buckles resolve into one larger buckle, which again drives the formation of the contraction pole—a protuberance of the zygote’s vegetal pole where maternal mRNAs accumulate. Thus, our findings reveal a mechanism where cortical actomyosin network flows determine cytoplasmic reorganization and cell shape by deforming adjacent cytoplasmic components through friction forces.","lang":"eng"}],"oa":1,"file_date_updated":"2024-07-16T12:12:43Z","publication_identifier":{"eissn":["1745-2481"],"issn":["1745-2473"]},"title":"Friction forces determine cytoplasmic reorganization and shape changes of ascidian oocytes upon fertilization"},{"dataavailabilitystatement":"All original microscopy data any additional information reported in this paper is available from the lead contact upon request.

Dynamic reorganization of adhesion receptors and the actomyosin cell cortex in space and time plays a central role in cell-cell contact formation and maturation. Nevertheless, how this process is mechanistically achieved when new contacts are formed remains unclear. Here, by building a biomimetic assay composed of progenitor cells adhering to supported lipid bilayers functionalized with E-cadherin ectodomains, we show that cortical F-actin flows, driven by the depletion of myosin-2 at the cell contact center, mediate the dynamic reorganization of adhesion receptors and cell cortex at the contact. E-cadherin-dependent downregulation of the small GTPase RhoA at the forming contact leads to both a depletion of myosin-2 and a decrease of F-actin at the contact center. At the contact rim, in contrast, myosin-2 becomes enriched by the retraction of bleb-like protrusions, resulting in a cortical tension gradient from the contact rim to its center. This tension gradient, in turn, triggers centrifugal F-actin flows, leading to further accumulation of F-actin at the contact rim and the progressive redistribution of E-cadherin from the contact center to the rim. Eventually, this combination of actomyosin downregulation and flows at the contact determines the characteristic molecular organization, with E-cadherin and F-actin accumulating at the contact rim, where they are needed to mechanically link the contractile cortices of the adhering cells.","lang":"eng"}],"external_id":{"pmid":["38134934"],"isi":["001154500400001"]},"publication_identifier":{"issn":["0960-9822"],"eissn":["1879-0445"]},"title":"Adhesion-induced cortical flows pattern E-cadherin-mediated cell contacts","file_date_updated":"2024-01-16T10:53:31Z","oa":1,"year":"2024","citation":{"mla":"Arslan, Feyza N., et al. “Adhesion-Induced Cortical Flows Pattern E-Cadherin-Mediated Cell Contacts.” <i>Current Biology</i>, vol. 34, no. 1, Elsevier, 2024, p. 171–182.e8, doi:<a href=\"https://doi.org/10.1016/j.cub.2023.11.067\">10.1016/j.cub.2023.11.067</a>.","ama":"Arslan FN, Hannezo EB, Merrin J, Loose M, Heisenberg C-PJ.
