We study if migration in vivo in such three-dimensionally confined environments requires changes in the mechanical properties of the surrounding cells using embryonic Drosophila melanogaster hemocytes, also called macrophages, as a model. We find that macrophage invasion into the germband through transient separation of the apposing ectoderm and mesoderm requires cell deformations and reductions in apical tension in the ectoderm. Interestingly, the genetic pathway governing these mechanical shifts acts downstream of the only known tumor necrosis factor superfamily member in Drosophila, Eiger, and its receptor, Grindelwald. Eiger-Grindelwald signaling reduces levels of active Myosin in the germband ectodermal cortex through the localization of a Crumbs complex component, Patj (Pals-1-associated tight junction protein). We therefore elucidate a distinct molecular pathway that controls tissue tension and demonstrate the importance of such regulation for invasive migration in vivo."}],"oa_version":"Published Version","ec_funded":1,"oa":1,"author":[{"last_name":"Ratheesh","orcid":"0000-0001-7190-0776","full_name":"Ratheesh, Aparna","first_name":"Aparna","id":"2F064CFE-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Biebl","first_name":"Julia","full_name":"Biebl, Julia","id":"3CCBB46E-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Smutny, Michael","first_name":"Michael","last_name":"Smutny"},{"last_name":"Veselá","first_name":"Jana","full_name":"Veselá, Jana","id":"433253EE-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Papusheva, Ekaterina","first_name":"Ekaterina","id":"41DB591E-F248-11E8-B48F-1D18A9856A87","last_name":"Papusheva"},{"last_name":"Krens","id":"2B819732-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-4761-5996","full_name":"Krens, Gabriel","first_name":"Gabriel"},{"id":"3F99E422-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9735-5315","full_name":"Kaufmann, Walter","first_name":"Walter","last_name":"Kaufmann"},{"orcid":"0000-0002-1819-198X","first_name":"Attila","full_name":"György, Attila","id":"3BCEDBE0-F248-11E8-B48F-1D18A9856A87","last_name":"György"},{"last_name":"Casano","id":"3DBA3F4E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6009-6804","full_name":"Casano, Alessandra M","first_name":"Alessandra M"},{"last_name":"Siekhaus","id":"3D224B9E-F248-11E8-B48F-1D18A9856A87","full_name":"Siekhaus, Daria E","first_name":"Daria E","orcid":"0000-0001-8323-8353"}],"ddc":["570"],"date_updated":"2026-06-18T18:37:46Z","language":[{"iso":"eng"}],"department":[{"_id":"DaSi"},{"_id":"CaHe"},{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"MiSi"}],"date_created":"2018-12-11T11:45:44Z","acknowledged_ssus":[{"_id":"SSU"}],"publisher":"Elsevier","article_type":"original","isi":1,"intvolume":"        45","corr_author":"1","page":"331 - 346","external_id":{"isi":["000432461400009"],"pmid":["29738712"]},"citation":{"mla":"Ratheesh, Aparna, et al. “Drosophila TNF Modulates Tissue Tension in the Embryo to Facilitate Macrophage Invasive Migration.” <i>Developmental Cell</i>, vol. 45, no. 3, Elsevier, 2018, pp. 331–46, doi:<a href=\"https://doi.org/10.1016/j.devcel.2018.04.002\">10.1016/j.devcel.2018.04.002</a>.","chicago":"Ratheesh, Aparna, Julia Bicher, Michael Smutny, Jana Veselá, Ekaterina Papusheva, Gabriel Krens, Walter Kaufmann, Attila György, Alessandra M Casano, and Daria E Siekhaus. “Drosophila TNF Modulates Tissue Tension in the Embryo to Facilitate Macrophage Invasive Migration.” <i>Developmental Cell</i>.

The Arabidopsis root is a widely used model for developmental, physiological and cell biological studies. Live imaging greatly aids these efforts, but the horizontal sample position and continuous root tip displacement present significant difficulties. Here, we develop a confocal microscope setup for vertical sample mounting and integrated directional illumination. We present TipTracker – a custom software for automatic tracking of diverse moving objects usable on various microscope setups. Combined, this enables observation of root tips growing along the natural gravity vector over prolonged periods of time, as well as the ability to induce rapid gravity or light stimulation. We also track migrating cells in the developing zebrafish embryo, demonstrating the utility of this system in the acquisition of high-resolution data sets of dynamic samples. We provide detailed descriptions of the tools enabling the easy implementation on other microscopes.","lang":"eng"}],"scopus_import":"1","title":"Live tracking of moving samples in confocal microscopy for vertically grown roots","_id":"946","article_number":"e26792","year":"2017","file":[{"relation":"main_file","date_created":"2018-12-12T10:17:57Z","content_type":"application/pdf","creator":"system","access_level":"open_access","file_size":19581847,"file_id":"5315","file_name":"IST-2017-847-v1+1_elife-26792-v2.pdf","checksum":"9af3398cb0d81f99d79016a616df22e9","date_updated":"2020-07-14T12:48:15Z"}],"acknowledgement":"Funding: Marie Curie Actions (FP7/2007-2013 no 291734) to Daniel von Wangenheim; Austrian Science Fund (M 2128-B21) to Matyáš Fendrych; Austrian Science Fund (FWF01_I1774S) to Eva Benková; European Research Council (FP7/2007-2013 no 282300) to Jiří Friml. \r\nThe authors are grateful to the Miba Machine Shop at IST Austria for their contribution to the microscope setup and to Yvonne Kemper for reading, understanding and correcting the manuscript.\r\n#BioimagingFacility","date_published":"2017-06-19T00:00:00Z","type":"journal_article","related_material":{"record":[{"status":"public","id":"5566","relation":"popular_science"}]},"status":"public","acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"Bio"}],"publisher":"eLife Sciences Publications","date_created":"2018-12-11T11:49:21Z","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"intvolume":"         6","pubrep_id":"847","isi":1,"citation":{"apa":"von Wangenheim, D., Hauschild, R., Fendrych, M., Barone, V., Benková, E., &#38; Friml, J.

Mother cells inheriting old poles are phenotypically distinct and display increased drug efflux activity relative to daughters. Consequently, we find systematic and long-lived growth differences between mother and daughter cells in the presence of subinhibitory drug concentrations. A simple model for biased partitioning predicts a population structure of long-lived and highly heterogeneous phenotypes.

How monolayers cooperate with the penetrating cells to support their transit is poorly understood. We studied dendritic cell (DC) entry into lymphatic capillaries as a model system for transendothelial migration. We find that the chemokine CCL21, which is the decisive guidance cue for intravasation, mainly localizes in the trans-Golgi network and intracellular vesicles of lymphatic endothelial cells. Upon DC transmigration, these Golgi deposits disperse and CCL21 becomes extracellularly enriched at the sites of endothelial cell-cell junctions. When we reconstitute the transmigration process in vitro, we find that secretion of CCL21-positive vesicles is triggered by a DC contact-induced calcium signal, and selective calcium chelation in lymphatic endothelium attenuates transmigration. Altogether, our data demonstrate a chemokine-mediated feedback between DCs and lymphatic endothelium, which facilitates transendothelial migration.","lang":"eng"}],"publist_id":"7052","oa":1,"ec_funded":1,"ddc":["570"],"author":[{"last_name":"Vaahtomeri","first_name":"Kari","full_name":"Vaahtomeri, Kari","orcid":"0000-0001-7829-3518","id":"368EE576-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Brown","id":"3DAB9AFC-F248-11E8-B48F-1D18A9856A87","first_name":"Markus","full_name":"Brown, Markus"},{"last_name":"Hauschild","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","full_name":"Hauschild, Robert","first_name":"Robert","orcid":"0000-0001-9843-3522"},{"id":"4C7D837E-F248-11E8-B48F-1D18A9856A87","first_name":"Ingrid","full_name":"De Vries, Ingrid","last_name":"De Vries"},{"id":"3B1B77E4-F248-11E8-B48F-1D18A9856A87","full_name":"Leithner, Alexander F","first_name":"Alexander F","orcid":"0000-0002-1073-744X","last_name":"Leithner"},{"orcid":"0000-0001-8599-1226","full_name":"Mehling, Matthias","first_name":"Matthias","id":"3C23B994-F248-11E8-B48F-1D18A9856A87","last_name":"Mehling"},{"first_name":"Walter","full_name":"Kaufmann, Walter","orcid":"0000-0001-9735-5315","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","last_name":"Kaufmann"},{"id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179","first_name":"Michael K","full_name":"Sixt, Michael K","last_name":"Sixt"}],"date_updated":"2025-09-10T14:27:34Z","department":[{"_id":"MiSi"},{"_id":"Bio"},{"_id":"EM-Fac"}],"language":[{"iso":"eng"}],"publisher":"Cell Press","date_created":"2018-12-11T11:47:50Z","tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"},"intvolume":"        19","isi":1,"pubrep_id":"900","fulldoi":"https://doi.org/10.1016/j.celrep.2017.04.027","citation":{"ama":"Vaahtomeri K, Brown M, Hauschild R, et al.

Gradients can either be soluble or immobilized to tissues as demonstrated for the haptotactic migration of dendritic cells (DCs) toward higher concentrations of immobilized chemokine CCL21. To elucidate how gradient characteristics govern cellular response patterns, we here introduce an in vitro system allowing to track migratory responses of DCs to precisely controlled immobilized gradients of CCL21. We find that haptotactic sensing depends on the absolute CCL21 concentration and local steepness of the gradient, consistent with a scenario where DC directionality is governed by the signal-to-noise ratio of CCL21 binding to the receptor CCR7. We find that the conditions for optimal DC guidance are perfectly provided by the CCL21 gradients we measure in vivo. Furthermore, we find that CCR7 signal termination by the G-protein-coupled receptor kinase 6 (GRK6) is crucial for haptotactic but dispensable for chemotactic CCL21 gradient sensing in vitro and confirm those observations in vivo. These findings suggest that stable, tissue-bound CCL21 gradients as sustainable “roads” ensure optimal guidance in vivo."}],"publist_id":"7050","publication_status":"published","project":[{"_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme","call_identifier":"FP7","grant_number":"291734"},{"call_identifier":"FWF","grant_number":"Y 564-B12","_id":"25A8E5EA-B435-11E9-9278-68D0E5697425","name":"Cytoskeletal force generation and force transduction of migrating leukocytes"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","article_processing_charge":"No","publication_identifier":{"issn":["09609822"]},"month":"05","quality_controlled":"1","_id":"674","year":"2017","date_published":"2017-05-09T00:00:00Z","type":"journal_article","status":"public","scopus_import":"1","title":"Dendritic cells interpret haptotactic chemokine gradients in a manner governed by signal to noise ratio and dependent on GRK6","intvolume":"        27","isi":1,"citation":{"ista":"Schwarz J, Bierbaum V, Vaahtomeri K, Hauschild R, Brown M, de Vries I, Leithner AF, Reversat A, Merrin J, Tarrant T, Bollenbach MT, Sixt MK. 2017.

In vitro reconstitution studies suggest that the structure and the dynamics of actin networks respond to mechanical forces. We demonstrate that lamellipodial actin of migrating cells responds to mechanical load when membrane tension is modulated. In a steady state, migrating cell filaments assume the canonical dendritic geometry, defined by Arp2/3-generated 70° branch points. Increased tension triggers a dense network with a broadened range of angles, whereas decreased tension causes a shift to a sparse configuration dominated by filaments growing perpendicularly to the plasma membrane. We show that these responses emerge from the geometry of branched actin: when load per filament decreases, elongation speed increases and perpendicular filaments gradually outcompete others because they polymerize the shortest distance to the membrane, where they are protected from capping. This network-intrinsic geometrical adaptation mechanism tunes protrusive force in response to mechanical load."}],"publist_id":"6951","publication":"Cell","volume":171,"issue":"1","doi":"10.1016/j.cell.2017.07.051","day":"21","publication_identifier":{"issn":["0092-8674"]},"article_processing_charge":"No","quality_controlled":"1","month":"09","project":[{"grant_number":"LS13-029","name":"Modeling of Polarization and Motility of Leukocytes in Three-Dimensional Environments","_id":"25AD6156-B435-11E9-9278-68D0E5697425"},{"name":"Cytoskeletal force generation and force transduction of migrating leukocytes","_id":"25A603A2-B435-11E9-9278-68D0E5697425","grant_number":"281556","call_identifier":"FP7"}],"publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2017-09-21T00:00:00Z","status":"public","type":"journal_article","year":"2017","_id":"727","scopus_import":"1","title":"Load adaptation of lamellipodial actin networks"},{"author":[{"last_name":"Von Wangenheim","id":"49E91952-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6862-1247","first_name":"Daniel","full_name":"Von Wangenheim, Daniel"},{"id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9843-3522","first_name":"Robert","full_name":"Hauschild, Robert","last_name":"Hauschild"},{"last_name":"Friml","orcid":"0000-0002-8302-7596","full_name":"Friml, Jirí","first_name":"Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87"}],"ddc":["580"],"ec_funded":1,"oa":1,"department":[{"_id":"JiFr"},{"_id":"Bio"}],"language":[{"iso":"eng"}],"date_updated":"2026-08-12T14:11:08Z","date_created":"2018-12-11T11:50:01Z","acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"Bio"}],"publisher":"MyJove Corporation","external_id":{"isi":["000397847200041"]},"citation":{"ieee":"D. von Wangenheim, R.

Differences in cell adhesion and cortex tension are commonly thought to drive cell sorting by regulating tissue surface tension (TST). However, the role that differential TST plays in cell segregation within the developing embryo is as yet unclear. Here, we have analyzed the role of differential TST for germ layer progenitor cell segregation during zebrafish gastrulation. Contrary to previous observations that differential TST drives germ layer progenitor cell segregation in vitro, we show that germ layers display indistinguishable TST within the gastrulating embryo, arguing against differential TST driving germ layer progenitor cell segregation in vivo. We further show that the osmolarity of the interstitial fluid (IF) is an important factor that influences germ layer TST in vivo, and that lower osmolarity of the IF compared with standard cell culture medium can explain why germ layers display differential TST in culture but not in vivo. Finally, we show that directed migration of mesendoderm progenitors is required for germ layer progenitor cell segregation and germ layer formation.","lang":"eng"}],"publist_id":"7047","pmid":1,"publication_status":"published","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","has_accepted_license":"1","article_processing_charge":"No","publication_identifier":{"issn":["0950-1991"]},"month":"05","quality_controlled":"1","_id":"676","file":[{"access_level":"open_access","file_size":8194516,"file_name":"2017_Development_Krens.pdf","file_id":"6905","checksum":"bc25125fb664706cdf180e061429f91d","date_updated":"2020-07-14T12:47:39Z","creator":"dernst","date_created":"2019-09-24T06:56:22Z","content_type":"application/pdf","relation":"main_file"}],"year":"2017","date_published":"2017-05-15T00:00:00Z","type":"journal_article","related_material":{"record":[{"id":"961","status":"public","relation":"dissertation_contains"},{"relation":"dissertation_contains","status":"public","id":"50"}]},"status":"public","scopus_import":"1","title":"Interstitial fluid osmolarity modulates the action of differential tissue surface tension in progenitor cell segregation during gastrulation","intvolume":"       144","article_type":"original","isi":1,"citation":{"ieee":"G.

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.","lang":"eng"}],"publist_id":"7074","oa_version":"Submitted Version","day":"27","doi":"10.1038/ncb3492","publication":"Nature Cell Biology","volume":19,"month":"03","quality_controlled":"1","article_processing_charge":"No","publication_identifier":{"issn":["1465-7392"]},"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","pmid":1,"publication_status":"published","project":[{"grant_number":"306589","call_identifier":"FP7","name":"Decoding the complexity of turbulence at its origin","_id":"25152F3A-B435-11E9-9278-68D0E5697425"},{"name":"Control of Epithelial Cell Layer Spreading in Zebrafish","_id":"252ABD0A-B435-11E9-9278-68D0E5697425","grant_number":"I930-B20","call_identifier":"FWF"}],"related_material":{"record":[{"status":"public","id":"8350","relation":"dissertation_contains"},{"status":"public","id":"50","relation":"dissertation_contains"}]},"type":"journal_article","status":"public","date_published":"2017-03-27T00:00:00Z","main_file_link":[{"url":"https://europepmc.org/articles/pmc5635970","open_access":"1"}],"_id":"661","year":"2017","title":"Friction forces position the neural anlage","scopus_import":"1"},{"title":"A microfluidic device for measuring cell migration towards substrate bound and soluble chemokine gradients","scopus_import":"1","article_number":"36440","_id":"1154","year":"2016","file":[{"creator":"system","access_level":"open_access","file_name":"IST-2017-744-v1+1_srep36440.pdf","date_updated":"2018-12-12T10:09:32Z","file_id":"4756","file_size":2353456,"relation":"main_file","content_type":"application/pdf","date_created":"2018-12-12T10:09:32Z"}],"type":"journal_article","status":"public","date_published":"2016-11-07T00:00:00Z","acknowledgement":"This work was supported by the Swiss National Science Foundation (Ambizione fellowship; PZ00P3-154733 to M.M.), the Swiss Multiple Sclerosis Society (research support to M.M.), a fellowship from the Boehringer Ingelheim Fonds (BIF) to J.S., the European Research Council (grant ERC GA 281556) and a START award from the Austrian Science Foundation (FWF) to M.S. #BioimagingFacility","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","project":[{"call_identifier":"FP7","grant_number":"281556","_id":"25A603A2-B435-11E9-9278-68D0E5697425","name":"Cytoskeletal force generation and force transduction of migrating leukocytes"},{"call_identifier":"FWF","grant_number":"Y 564-B12","_id":"25A8E5EA-B435-11E9-9278-68D0E5697425","name":"Cytoskeletal force generation and force transduction of migrating leukocytes"}],"publication_status":"published","month":"11","quality_controlled":"1","has_accepted_license":"1","article_processing_charge":"No","doi":"10.1038/srep36440","day":"07","volume":6,"publication":"Scientific Reports","file_date_updated":"2018-12-12T10:09:32Z","abstract":[{"text":"Cellular locomotion is a central hallmark of eukaryotic life. It is governed by cell-extrinsic molecular factors, which can either emerge in the soluble phase or as immobilized, often adhesive ligands. To encode for direction, every cue must be present as a spatial or temporal gradient. Here, we developed a microfluidic chamber that allows measurement of cell migration in combined response to surface immobilized and soluble molecular gradients. As a proof of principle we study the response of dendritic cells to their major guidance cues, chemokines. The majority of data on chemokine gradient sensing is based on in vitro studies employing soluble gradients. Despite evidence suggesting that in vivo chemokines are often immobilized to sugar residues, limited information is available how cells respond to immobilized chemokines. We tracked migration of dendritic cells towards immobilized gradients of the chemokine CCL21 and varying superimposed soluble gradients of CCL19. Differential migratory patterns illustrate the potential of our setup to quantitatively study the competitive response to both types of gradients. Beyond chemokines our approach is broadly applicable to alternative systems of chemo- and haptotaxis such as cells migrating along gradients of adhesion receptor ligands vs. any soluble cue. \r\n","lang":"eng"}],"publist_id":"6204","oa_version":"Published Version","ec_funded":1,"oa":1,"author":[{"last_name":"Schwarz","full_name":"Schwarz, Jan","first_name":"Jan","id":"346C1EC6-F248-11E8-B48F-1D18A9856A87"},{"id":"3FD04378-F248-11E8-B48F-1D18A9856A87","full_name":"Bierbaum, Veronika","first_name":"Veronika","last_name":"Bierbaum"},{"last_name":"Merrin","id":"4515C308-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5145-4609","full_name":"Merrin, Jack","first_name":"Jack"},{"full_name":"Frank, Tino","first_name":"Tino","last_name":"Frank"},{"last_name":"Hauschild","orcid":"0000-0001-9843-3522","first_name":"Robert","full_name":"Hauschild, Robert","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Bollenbach","first_name":"Mark Tobias","full_name":"Bollenbach, Mark Tobias","orcid":"0000-0003-4398-476X","id":"3E6DB97A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Tay, Savaş","first_name":"Savaş","last_name":"Tay"},{"last_name":"Sixt","full_name":"Sixt, Michael K","first_name":"Michael K","orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87"},{"id":"3C23B994-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8599-1226","first_name":"Matthias","full_name":"Mehling, Matthias","last_name":"Mehling"}],"ddc":["579"],"department":[{"_id":"MiSi"},{"_id":"NanoFab"},{"_id":"Bio"},{"_id":"ToBo"}],"language":[{"iso":"eng"}],"date_updated":"2025-09-22T09:56:13Z","date_created":"2018-12-11T11:50:27Z","publisher":"Nature Publishing Group","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"pubrep_id":"744","isi":1,"intvolume":"         6","external_id":{"isi":["000387118300001"]},"citation":{"short":"J.

Polymerization requires an initial nucleation step, which is mediated by factors establishing either parallel filaments in the case of filopodia or branched filaments that form the branched lamellipodial network. Branches are considered essential for regular cell motility and are initiated by the Arp2/3 complex, which in turn is activated by nucleation-promoting factors of the WASP and WAVE families. Here we employed rapid amoeboid crawling leukocytes and found that deletion of the WAVE complex eliminated actin branching and thus lamellipodia formation. The cells were left with parallel filaments at the leading edge, which translated, depending on the differentiation status of the cell, into a unipolar pointed cell shape or cells with multiple filopodia. Remarkably, unipolar cells migrated with increased speed and enormous directional persistence, while they were unable to turn towards chemotactic gradients. Cells with multiple filopodia retained chemotactic activity but their migration was progressively impaired with increasing geometrical complexity of the extracellular environment. These findings establish that diversified leading edge protrusions serve as explorative structures while they slow down actual locomotion."}],"publist_id":"5949","project":[{"name":"Cytoskeletal force generation and force transduction of migrating leukocytes","_id":"25A603A2-B435-11E9-9278-68D0E5697425","grant_number":"281556","call_identifier":"FP7"}],"publication_status":"published","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","article_processing_charge":"No","has_accepted_license":"1","quality_controlled":"1","month":"10"}]
