Objective to observe the role of platelet-derived growth factor-B (PDGF-B) in the regeneration of peripheral nerve by studying its expression on injured rat sciatic nerves.

Objective: to investigate the effect of platelet derived growth factor (PDGF) and heparin on regulating the transformation of phenotype and collagen synthesis in aorta smooth muscle cell (SMC).

Objective to investigate the intracellular calcium concentration alteration induced by platelet-derived growth factor BB (PDGF-BB) and the mechanism of ion flux in cultured glomerular mesangial cells.
