| Research Abstract |
The motility of cancer cells in 3D matrices is of two types : mesenchymal motility, in which the cells are elongated and amoeboid motility, in which the cells are round. Amoeboid motility is driven by an actomyosin-based contractile force, which is regulated by the Rho/ROCK pathway. Here I show that the motility of elongated cells is regulated by Rac signaling through formation of elongated pseudopodia and cell-substrate adhesion.
