Cell-cell communication during collective migration.
Cell motility plays a critical role in many biological and medical processes, including wound healing, morphogenesis, and cancer metastasis (1). Often, this movement is guided by external chemical cues in the form of chemoattractant gradients. These cues consist of diffusive chemoattractant molecules that bind to surface receptors on the cell membrane and activate intracellular signaling pathwa...
متن کاملNeighborly relations during collective migration.
The collective migration of sheets, cohorts, chains or streams of cells contributes to embryogenesis, tissue remodeling and repair as well as to cancer invasion. The functional coordination between neighboring cells is at the heart of collective migration, during which cells migrate with a similar speed in an identical direction. Far from being the result of the simultaneous migration of isolat...
متن کاملPhysical forces during collective cell migration
Fundamental biological processes including morphogenesis, tissue repair and tumour metastasis require collective cell motions1–3, and to drive these motions cells exert traction forces on their surroundings4. Current understanding emphasizes that these traction forces arise mainly in ‘leader cells’ at the front edge of the advancing cell sheet5–9. Our data are contrary to that assumption and sh...
متن کاملTousled-like kinase regulates cytokine-mediated communication between cooperating cell types during collective border cell migration
Collective cell migration is emerging as a major contributor to normal development and disease. Collective movement of border cells in the Drosophila ovary requires cooperation between two distinct cell types: four to six migratory cells surrounding two immotile cells called polar cells. Polar cells secrete a cytokine, Unpaired (Upd), which activates JAK/STAT signaling in neighboring cells, sti...
متن کاملNonautonomous contact guidance signaling during collective cell migration.
Directed migration of groups of cells is a critical aspect of tissue morphogenesis that ensures proper tissue organization and, consequently, function. Cells moving in groups, unlike single cells, must coordinate their migratory behavior to maintain tissue integrity. During directed migration, cells are guided by a combination of mechanical and chemical cues presented by neighboring cells and t...
