Cell migration
Videos
Cell migration is the movement of cells, either individually or as a group. It is a central process in the development and maintenance of multicellular organisms: tissue formation during embryonic dev

(A) Dynamic microtubules are necessary for tail retraction and are distributed at the rear end in a migrating cell. Green, highly dynamic microtubules; yellow, moderately dynamic microtubules and red, stable microtubules. (B) Stable microtubules act as struts and prevent tail retraction and thereby inhibit cell migration.

Integrin
Videos
Integrins are transmembrane receptors that help cell–cell and cell–extracellular matrix adhesion. Upon ligand binding, integrins activate signal transduction pathways that mediate cellular signals suc
Cell migration
…rather than a bubble-like structure (or bleb) at its front. For a cell to move, it is necessary to bring a fresh supply of "feet" (proteins called integrins, which attach a cell to the surface on which it is crawling) to the front. It is likely that these feet are endocytosed toward the rear of the cell and…
