Segregation is driven by differential tissue surface tensions generated by cell types through controlling cell-cell contact formation by regulating adhesion and actomyosin contractility-based cellular cortical tensions. We use vertebrate tissue cell types and zebrafish germ layer progenitors as in vitro models of 3-dimensional heterotypic segregation and developed a quantitative analysis of their dynamics based on 3D time-lapse microscopy. We show that general inhibition of actomyosin contractility by the Rho kinase inhibitor Y27632 delays segregation. Cell type-specific inhibition of non-muscle myosin2 activity by overexpression of myosin assembly inhibitor S100A4 reduces tissue surface tension, manifested in decreased compaction during aggregation and inverted geometry observed during segregation. The same is observed when we express a constitutively active Rho kinase isoform to ubiquitously keep actomyosin contractility high at cell-cell and cell-medium interfaces and thus overriding the interface-specific regulation of cortical tensions. Tissue surface tension regulation can become an effective tool in tissue engineering.}, year = {2023}, eissn = {2399-3642}, orcid-numbers = {Méhes, Előd/0000-0003-2697-907X; Varga, Máté/0000-0003-4289-1705; Biri-Kovács, Beáta/0000-0001-5803-9969; Nyitray, László/0000-0003-4717-5994; Heisenberg, Carl-Philipp/0000-0002-0912-4566; Vicsek, Tamás/0000-0003-1431-2884} } @article{MTMT:33767422, title = {Emergence of synchronised rotations in dense active matter with disorder}, url = {https://m2.mtmt.hu/api/publication/33767422}, author = {Vahabli, D. and Vicsek, Tamás}, doi = {10.1038/s42005-023-01173-5}, journal-iso = {COMM PHYS}, journal = {COMMUNICATIONS PHYSICS}, volume = {6}, unique-id = {33767422}, issn = {2399-3650}, year = {2023}, eissn = {2399-3650}, orcid-numbers = {Vicsek, Tamás/0000-0003-1431-2884} } @article{MTMT:32337574, title = {Anomalous diffusion in the citation time series of scientific publications}, url = {https://m2.mtmt.hu/api/publication/32337574}, author = {Zamani, Maryam and Aghion, Erez and Pollner, Péter and Vicsek, Tamás and Kantz, Holger}, doi = {10.1088/2632-072X/ac24f1}, journal-iso = {J PHYS COMPLEX}, journal = {JOURNAL OF PHYSICS - COMPLEXITY}, volume = {2}, unique-id = {32337574}, issn = {2632-072X}, year = {2021}, orcid-numbers = {Zamani, Maryam/0000-0003-0120-573X; Pollner, Péter/0000-0003-0464-4893; Vicsek, Tamás/0000-0003-1431-2884; Kantz, Holger/0000-0001-6921-6094} } @misc{MTMT:31657027, title = {Synergistic Benefits of Group Search in Rats - tudományos video abstract}, url = {https://m2.mtmt.hu/api/publication/31657027}, author = {Molnár, Attila Dávid and Jurkovics, Milán and Máté, Nagy and Horicsányi, Attila and Kubinyi, Enikő and Iain, D.Couzin and Vásárhelyi, Gábor and Andrea, Flack and Vicsek, Tamás}, unique-id = {31657027}, abstract = {Locating unpredictable but essential resources is a task that all mobile animals have to perform in order to survive and reproduce. Research on search strategies has focused largely on independent individuals [1, 2, 3], but many organisms display collective behaviors, including during group search and foraging [4, 5, 6]. One classical experimental search task, informing studies of navigation, memory, and learning, is the location of a reward in a confined, complex maze setting [7, 8]. Rats (Rattus norvegicus) have been paradigmatic in psychological and biological studies [9, 10], but despite rats being highly social [11, 12], their group search behavior has not been investigated. Here, we explore the decision making of rats searching individually, or in groups, for a reward in a complex maze environment. Using automated video tracking, we find that rats exhibit—even when alone—a partially systematic search, leading to a continuous increase in their chance of finding the reward because of increased attraction to unexplored regions. When searching together, however, synergistic group advantages arise through integration of individual exploratory and social behavior. The superior search performances result from a strategy that represents a hierarchy of influential preferences in response to social and asocial cues. Furthermore, we present a computational model to compare the essential factors that influence how collective search operates and to validate that the collective search strategy increases the search efficiency of individuals in groups. This strategy can serve as direct inspiration for designing computational search algorithms and systems, such as autonomous robot groups, to explore areas inaccessible to humans.}, year = {2020}, orcid-numbers = {Kubinyi, Enikő/0000-0002-4468-9845; Vásárhelyi, Gábor/0000-0002-5797-2340; Vicsek, Tamás/0000-0003-1431-2884} } @article{MTMT:31610613, title = {Synergistic Benefits of Group Search in Rats}, url = {https://m2.mtmt.hu/api/publication/31610613}, author = {Nagy, Máté and Horicsányi, Attila and Kubinyi, Enikő and Couzin, Iain D. and Vásárhelyi, Gábor and Flack, Andrea and Vicsek, Tamás}, doi = {10.1016/j.cub.2020.08.079}, journal-iso = {CURR BIOL}, journal = {CURRENT BIOLOGY}, volume = {30}, unique-id = {31610613}, issn = {0960-9822}, year = {2020}, eissn = {1879-0445}, pages = {4733-4738.e4}, orcid-numbers = {Nagy, Máté/0000-0001-8817-087X; Kubinyi, Enikő/0000-0002-4468-9845; Vásárhelyi, Gábor/0000-0002-5797-2340; Vicsek, Tamás/0000-0003-1431-2884} }
