Cell behaviors regulated by guidance cues in collective migration of border cells
Border cells perform a collective, invasive, and directed migration during Drosophila melanogaster oogenesis. Two receptor tyrosine kinases (RTKs), the platelet-derived growth factor/vascular endothelial growth factor-related receptor (PVR) and the epidermal growth factor receptor (EGFR), are important for reading guidance cues, but how these cues steer migration is not well understood. During ...
متن کاملCollective guidance of collective cell migration.
Some cells migrate and find their way as solitary entities. However, during development of multicellular animals and possibly during tumor dissemination, cells often move as groups, associated tightly or loosely. Recent advances in live imaging have aided examination of such 'multicellular cell biology'. Here, I propose a model for how a group of cells can process and react to guidance informat...
متن کاملQuantitative 3D analysis of complex single border cell behaviors in coordinated collective cell migration
Understanding the mechanisms of collective cell migration is crucial for cancer metastasis, wound healing and many developmental processes. Imaging a migrating cluster in vivo is feasible, but the quantification of individual cell behaviours remains challenging. We have developed an image analysis toolkit, CCMToolKit, to quantify the Drosophila border cell system. In addition to chaotic motion,...
متن کاملMultiscale Cues Drive Collective Cell Migration
To investigate complex biophysical relationships driving directed cell migration, we developed a biomimetic platform that allows perturbation of microscale geometric constraints with concomitant nanoscale contact guidance architectures. This permits us to elucidate the influence, and parse out the relative contribution, of multiscale features, and define how these physical inputs are jointly pr...
متن کاملS20-02 Collective migration of border cells in Drosophila
Primordial germ cell (PGC) migration in zebrafish is directed by the chemokine SDF-1a that activates its receptor CXCR4b. Guided PGC migration in zebrafish thus serves as a model for chemokinedirected cell migration, a process that is relevant for a wide range of events in development, homeostasis and disease. We show that during their migration PGCs generate bleb-like protrusions that are powe...
