ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between hypoxia and the apoptosis of corpus cavernosum smooth muscle cells (CCSMC) in SD rats.</p><p><b>METHODS</b>CCSMCs were cultured in vitro and identified by immunohistochemistry, and then underwent hypoxia interference at the concentration of 1% O2 for 12, 24, 48 and 72 hours, with normal oxygen concentration as the control. Flow cytometry was used to determine the cycles and apoptosis of the cells.</p><p><b>RESULTS</b>The cultured CCSMCs grew well, positive for anti-smooth muscle alpha-actin monoclonal antibody immunohistochemical staining. Flow cytometry showed that the number of CCSMCs in G0/G1 was gradually increased within 48 hours and then decreased, just opposite to the proportion of the S phase cells. But no regular change was found in the proportion of the cells in the G2/M phase.</p><p><b>CONCLUSION</b>Hypoxia promotes the apoptosis of CCSMCs in a time-dependent manner, to the maximum at 48 hours, and then cell lysis may occur, but with no further apoptosis.</p>
