Semaphorin3a Increases Focal Adhesion Formation To Shift The Relationship Between Cell Migration And Substratum Concentration Through A Rock-Dependent Mechanism, Frances V. Compere, Scott Gehler
Celebration of Learning
Cell migration is essential for many life processes, including wound healing, embryonic development and cancer metastasis. Cells move across a surface by interacting and forming adhesions with the molecules in their environment, specifically the extracellular matrix. Past studies have shown that there is an optimal level of cell-substratum adhesive strength that allows for the most cell migration and spreading (DiMilla et al., 1993; Gaudet et al., 2003). The mechanism by which this works is not well understood, however. Semaphorin 3A (Sema3A) has been shown to increase the expression of integrin receptors, which help mediate the formation of the adhesions between ...
