Collective Cell Migration


Project Description

Collective cell migration (CCM) can be described as a large scale coordinated movement of cells that are in close proximity with each other. It is a phenomenon that is observed not only in physiological processes such as that found in embryogenesis and wound healing, but also in pathophysiological processes such as cancer metastasis. Some of the factors influencing this concerted process include cell–cell adhesion, cell–substrate interaction and mechanical cues such as geometrical constraints among others. Here, we study CCM arising from geometrical constraints, formation of suspended epithelial bridges and mechanisms involved in wound closure.
