[{"abstract":[{"lang":"eng","text":"Interstitial fluid (IF) accumulation between embryonic cells is thought to be important for embryo patterning and morphogenesis. Here, we identify a positive mechanical feedback loop between cell migration and IF relocalization and find that it promotes embryonic axis formation during zebrafish gastrulation. We show that anterior axial mesendoderm (prechordal plate [ppl]) cells, moving in between the yolk cell and deep cell tissue to extend the embryonic axis, compress the overlying deep cell layer, thereby causing IF to flow from the deep cell layer to the boundary between the yolk cell and the deep cell layer, directly ahead of the advancing ppl. This IF relocalization, in turn, facilitates ppl cell protrusion formation and migration by opening up the space into which the ppl moves and, thereby, the ability of the ppl to trigger IF relocalization by pushing against the overlying deep cell layer. Thus, embryonic axis formation relies on a hydraulic feedback loop between cell migration and IF relocalization."}],"license":"https://creativecommons.org/licenses/by/4.0/","acknowledged_ssus":[{"_id":"PreCl"},{"_id":"Bio"}],"volume":58,"quality_controlled":"1","external_id":{"pmid":["36931269"],"isi":["000982111800001"]},"department":[{"_id":"CaHe"},{"_id":"Bio"}],"date_created":"2023-04-16T22:01:07Z","language":[{"iso":"eng"}],"corr_author":"1","publication_status":"published","file":[{"checksum":"c80ca2ebc241232aacdb5aa4b4c80957","content_type":"application/pdf","date_updated":"2023-04-17T07:41:25Z","creator":"dernst","file_name":"2023_DevelopmentalCell_Huljev.pdf","file_id":"12842","date_created":"2023-04-17T07:41:25Z","file_size":7925886,"access_level":"open_access","relation":"main_file","success":1}],"acknowledgement":"We thank Andrea Pauli (IMP) and Edouard Hannezo (ISTA) for fruitful discussions and support with the SPIM experiments; the Heisenberg group, and especially Feyza Nur Arslan and Alexandra Schauer, for discussions and feedback; Michaela Jović (ISTA) for help with the quantitative real-time PCR protocol; the bioimaging and zebrafish facilities of ISTA for continuous support; Stephan Preibisch (Janelia Research Campus) for support with the SPIM data analysis; and Nobuhiro Nakamura (Tokyo Institute of Technology) for sharing α1-Na+/K+-ATPase antibody.

Cytoskeletal rearrangements are thought to constitute the main drivers of cytoplasmic flows and reorganization. In contrast, remarkably little is known about how dynamic changes in size and shape of cell organelles affect cytoplasmic organization. Here, we show that within the maturing zebrafish oocyte, the surface localization of exocytosis-competent cortical granules (Cgs) upon germinal vesicle breakdown (GVBD) is achieved by the combined activities of yolk granule (Yg) fusion and microtubule aster formation and translocation. We find that Cgs are moved towards the oocyte surface through radially outward cytoplasmic flows induced by Ygs fusing and compacting towards the oocyte center in response to GVBD. We further show that vesicles decorated with the small Rab GTPase Rab11, a master regulator of vesicular trafficking and exocytosis, accumulate together with Cgs at the oocyte surface. This accumulation is achieved by Rab11-positive vesicles being transported by acentrosomal microtubule asters, the formation of which is induced by the release of CyclinB/Cdk1 upon GVBD, and which display a net movement towards the oocyte surface by preferentially binding to the oocyte actin cortex. We finally demonstrate that the decoration of Cgs by Rab11 at the oocyte surface is needed for Cg exocytosis and subsequent chorion elevation, a process central in egg activation. Collectively, these findings unravel a yet unrecognized role of organelle fusion, functioning together with cytoskeletal rearrangements, in orchestrating cytoplasmic organization during oocyte maturation."}],"volume":21,"quality_controlled":"1","date_created":"2023-07-16T22:01:09Z","external_id":{"pmid":["37289834"],"isi":["001003199100005"]},"department":[{"_id":"CaHe"}],"corr_author":"1","language":[{"iso":"eng"}],"publication_status":"published","pmid":1,"acknowledgement":"This work was supported by funding from the European Union (European Research Council Advanced grant 742573) to C.-P.H.

Immunological challenge causes LNs to increase more than tenfold in size within a few days. Here, we characterized the biomechanics of LN swelling on the cellular and organ scale. We identified lymphocyte trapping by influx and proliferation as drivers of an outward pressure force, causing fibroblastic reticular cells of the T-zone (TRCs) and their associated conduits to stretch. After an initial phase of relaxation, TRCs sensed the resulting strain through cell matrix adhesions, which coordinated local growth and remodeling of the stromal network. While the expanded TRC network readopted its typical configuration, a massive fibrotic reaction of the organ capsule set in and countered further organ expansion. Thus, different fibroblast populations mechanically control LN swelling in a multitier fashion.","lang":"eng"}],"acknowledged_ssus":[{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"PreCl"},{"_id":"LifeSc"}],"volume":23,"quality_controlled":"1","date_created":"2021-08-06T09:09:11Z","external_id":{"isi":["000822975900002"],"pmid":["35817845"]},"department":[{"_id":"SiHi"},{"_id":"CaHe"},{"_id":"EdHa"},{"_id":"EM-Fac"},{"_id":"Bio"},{"_id":"MiSi"}],"corr_author":"1","language":[{"iso":"eng"}],"publication_status":"published"},{"doi":"10.1016/j.devcel.2020.12.002","article_type":"original","_id":"9006","title":"Cytoplasm's got moves","month":"01","article_processing_charge":"No","citation":{"short":"S.

The structure of the cytoplasm is thought to be highly organized and heterogeneous due to the crowding of its constituents and their effective compartmentalization. In such an environment, the diffusive dynamics of the molecules is very restricted, an effect that is further amplified by clustering and anchoring of molecules. Despite the jammed nature of the cytoplasm at the microscopic scale, large-scale reorganization of cytoplasm is essential for important cellular functions, such as nuclear positioning and cell division. How such mesoscale reorganization of the cytoplasm is achieved, especially for very large cells such as oocytes or syncytial tissues that can span hundreds of micrometers in size, has only begun to be understood.\r\nIn this thesis, I focus on the recent advances in elucidating the molecular, cellular and biophysical principles underlying cytoplasmic organization across different scales, structures and species. First, I outline which of these principles have been identified by reductionist approaches, such as in vitro reconstitution assays, where boundary conditions and components can be modulated at ease. I then describe how the theoretical and experimental framework established in these reduced systems have been applied to their more complex in vivo counterparts, in particular oocytes and embryonic syncytial structures, and discuss how such complex biological systems can initiate symmetry breaking and establish patterning.\r\nSpecifically, I examine an example of large-scale reorganizations taking place in zebrafish embryos, where extensive cytoplasmic streaming leads to the segregation of cytoplasm from yolk granules along the animal-vegetal axis of the embryo. Using biophysical experimentation and theory, I investigate the forces underlying this process, to show that this process does not rely on cortical actin reorganization, as previously thought, but instead on a cell-cycle-dependent bulk actin polymerization wave traveling from the animal to the vegetal pole of the embryo. This wave functions in segregation by both pulling cytoplasm animally and pushing yolk granules vegetally. Cytoplasm pulling is mediated by bulk actin network flows exerting friction forces on the cytoplasm, while yolk granule pushing is achieved by a mechanism closely resembling actin comet formation on yolk granules. This study defines a novel role of bulk actin polymerization waves in embryo polarization via cytoplasmic segregation. Lastly, I describe the cytoplasmic reorganizations taking place during zebrafish oocyte maturation, where the initial segregation of the cytoplasm and yolk granules occurs. Here, I demonstrate a previously uncharacterized wave of microtubule aster formation, traveling the oocyte along the animal-vegetal axis. Further research is required to determine the role of such microtubule structures in cytoplasmic reorganizations therein.\r\nCollectively, these studies provide further evidence for the coupling between cell cytoskeleton and cell cycle machinery, which can underlie a core self-organizing mechanism for orchestrating large-scale reorganizations in a cell-cycle-tunable manner, where the modulations of the force-generating machinery and cytoplasmic mechanics can be harbored to fulfill cellular functions."}],"supervisor":[{"orcid":"0000-0002-0912-4566","full_name":"Heisenberg, Carl-Philipp J","last_name":"Heisenberg","id":"39427864-F248-11E8-B48F-1D18A9856A87","first_name":"Carl-Philipp J"},{"last_name":"Hof","full_name":"Hof, Björn","first_name":"Björn","id":"3A374330-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2057-2754"}],"acknowledged_ssus":[{"_id":"PreCl"},{"_id":"Bio"},{"_id":"EM-Fac"}],"department":[{"_id":"BjHo"},{"_id":"CaHe"}],"date_created":"2020-09-09T11:12:10Z","corr_author":"1","language":[{"iso":"eng"}],"degree_awarded":"PhD","publication_status":"published"},{"volume":177,"quality_controlled":"1","abstract":[{"text":"Segregation of maternal determinants within the oocyte constitutes the first step in embryo patterning.

However, remarkably little is known about whether and how the interplay between contact formation and fate specification affects development. Here, we identify a positive feedback loop between cell-cell contact duration, morphogen signaling, and mesendoderm cell-fate specification during zebrafish gastrulation. We show that long-lasting cell-cell contacts enhance the competence of prechordal plate (ppl) progenitor cells to respond to Nodal signaling, required for ppl cell-fate specification. We further show that Nodal signaling promotes ppl cell-cell contact duration, generating a positive feedback loop between ppl cell-cell contact duration and cell-fate specification. Finally, by combining mathematical modeling and experimentation, we show that this feedback determines whether anterior axial mesendoderm cells become ppl or, instead, turn into endoderm. Thus, the interdependent activities of cell-cell signaling and contact formation control fate diversification within the developing embryo.","lang":"eng"}],"quality_controlled":"1","volume":43},{"pmid":1,"oa":1,"publication_identifier":{"issn":["1465-7392"]},"main_file_link":[{"url":"https://europepmc.org/articles/pmc5635970","open_access":"1"}],"publication":"Nature Cell Biology","scopus_import":"1","author":[{"full_name":"Smutny, Michael","last_name":"Smutny","first_name":"Michael","id":"3FE6E4E8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-5920-9090"},{"last_name":"Ákos","full_name":"Ákos, Zsuzsa","first_name":"Zsuzsa"},{"first_name":"Silvia","full_name":"Grigolon, Silvia","last_name":"Grigolon"},{"last_name":"Shamipour","full_name":"Shamipour, Shayan","id":"40B34FE2-F248-11E8-B48F-1D18A9856A87","first_name":"Shayan"},{"first_name":"Verena","full_name":"Ruprecht, Verena","last_name":"Ruprecht"},{"orcid":"0000-0001-5199-9940","last_name":"Capek","full_name":"Capek, Daniel","id":"31C42484-F248-11E8-B48F-1D18A9856A87","first_name":"Daniel"},{"id":"3ECECA3A-F248-11E8-B48F-1D18A9856A87","first_name":"Martin","last_name":"Behrndt","full_name":"Behrndt, Martin"},{"last_name":"Papusheva","full_name":"Papusheva, Ekaterina","first_name":"Ekaterina","id":"41DB591E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Masazumi","last_name":"Tada","full_name":"Tada, Masazumi"},{"first_name":"Björn","id":"3A374330-F248-11E8-B48F-1D18A9856A87","last_name":"Hof","full_name":"Hof, Björn","orcid":"0000-0003-2057-2754"},{"last_name":"Vicsek","full_name":"Vicsek, Tamás","first_name":"Tamás"},{"first_name":"Guillaume","last_name":"Salbreux","full_name":"Salbreux, Guillaume"},{"full_name":"Heisenberg, Carl-Philipp J","last_name":"Heisenberg","first_name":"Carl-Philipp J","id":"39427864-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0912-4566"}],"isi":1,"intvolume":"        19","ec_funded":1,"volume":19,"quality_controlled":"1","abstract":[{"lang":"eng","text":"During embryonic development, mechanical forces are essential for cellular rearrangements driving tissue morphogenesis. Here, we show that in the early zebrafish embryo, friction forces are generated at the interface between anterior axial mesoderm (prechordal plate, ppl) progenitors migrating towards the animal pole and neurectoderm progenitors moving in the opposite direction towards the vegetal pole of the embryo. These friction forces lead to global rearrangement of cells within the neurectoderm and determine the position of the neural anlage. Using a combination of experiments and simulations, we show that this process depends on hydrodynamic coupling between neurectoderm and ppl as a result of E-cadherin-mediated adhesion between those tissues. Our data thus establish the emergence of friction forces at the interface between moving tissues as a critical force-generating process shaping the embryo."}],"acknowledged_ssus":[{"_id":"SSU"}],"publication_status":"published","date_created":"2018-12-11T11:47:46Z","department":[{"_id":"CaHe"},{"_id":"BjHo"},{"_id":"Bio"}],"external_id":{"isi":["000397917000009"],"pmid":["28346437"]},"language":[{"iso":"eng"}],"corr_author":"1","status":"public","publisher":"Nature Publishing Group","type":"journal_article","day":"27","project":[{"grant_number":"306589","_id":"25152F3A-B435-11E9-9278-68D0E5697425","name":"Decoding the complexity of turbulence at its origin","call_identifier":"FP7"},{"call_identifier":"FWF","name":"Control of Epithelial Cell Layer Spreading in Zebrafish","_id":"252ABD0A-B435-11E9-9278-68D0E5697425","grant_number":"I930-B20"}],"date_published":"2017-03-27T00:00:00Z","date_updated":"2026-04-28T22:31:01Z","oa_version":"Submitted Version","year":"2017","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","page":"306 - 317","_id":"661","month":"03","title":"Friction forces position the neural anlage","article_processing_charge":"No","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"8350"},{"relation":"dissertation_contains","status":"public","id":"50"}]},"citation":{"apa":"Smutny, M., Ákos, Z., Grigolon, S., Shamipour, S., Ruprecht, V., Capek, D., … Heisenberg, C.-P.
