Collective 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 کاملCollective cell migration in development
During embryonic development, tissues undergo major rearrangements that lead to germ layer positioning, patterning, and organ morphogenesis. Often these morphogenetic movements are accomplished by the coordinated and cooperative migration of the constituent cells, referred to as collective cell migration. The molecular and biomechanical mechanisms underlying collective migration of developing t...
متن کاملCollective cell migration in development.
Collective cell migration is a key process during the development of most organisms. It can involve either the migration of closely packed mesenchymal cells that make dynamic contacts with frequently changing neighbour cells, or the migration of epithelial sheets that typically display more stable cell-cell interactions and less frequent changes in neighbours. These collective movements can be ...
متن کاملCell-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 کاملMammary collective cell migration involves transient loss of epithelial features and individual cell migration within the epithelium.
Normal mammary morphogenesis involves transitions between simple and multilayered epithelial organizations. We used electron microscopy and molecular markers to determine whether intercellular junctions and apico-basal polarity were maintained in the multilayered epithelium. We found that multilayered elongating ducts had polarized apical and basal tissue surfaces both in three-dimensional cult...
