Staurosporine promotes endothelial cell assembly and FAK phosphorylation during in vitro angiogenesis.

In the present study, we report that staurosporine, a known PKC inhibitor, enhanced in vitro angiogenesis. Endothelial cells plated in a three-dimensional matrix formed cords and enclosed structures within 4-6 hours. The cells in cord structures became elongated during the subsequent incubation.
