Objective To observe the effects of recombinant sonic hedgehog (rShh) on the proliferation and apoptosis of cultured pulmonary microvascular endothelial cells (PMVECs) after exposure to seawater. Methods After PMVECs were primarily isolated from SD rats and cultured
and then the cells were exposed to seawater (from the South China Sea) and treated with 50
100
200 and 400 ng/ml rShh respectively for 24 h. Apoptotic rate of PMVECs was detected by TUNEL. The proliferation of PMVECs was examined by MTT assay. Results Seawater caused the proliferation of PMVECs inhibited and the apoptotic rate increased. rShh suppressed the inhibited proliferation and inhibited apoptosis of the cells in a dose-dependent manner. Conclusion RShh can promote the proliferation and inhibit the apoptosis of PMVECs exposed to seawater.
