Visualization of actin and focal adhesions in a live cell.

Time lapse movie of a cell microinjected with fluorescent actin (left) and expressing fluoresceent paxillin (right).

(from Gardel, et al. Traction stress in focal adhesions correlates biphasically with actin retrograde flow speed. JCB 183:6, 999-1005. 2008. Video 1)
