Rigidity Sensing at the Leading Edge through αvβ3 Integrins and RPTPα
Biophysical Journal, pp. 1804-1809, 2006.
Cells require optimal substrate stiffness for normal function and differentiation. The mechanisms for sensing matrix rigidity and durotaxis, however, are not clear. Here we showed that control, Shp2 −/− , integrin β 1 −/− , and talin1 −/− cell lines all spread to a threefold greater area on fibronectin (FN)-coated rigid polyacrylamide sur...More
