Fig. 3From: The alveolar epithelial cells are involved in pulmonary vascular remodeling and constriction of hypoxic pulmonary hypertensionEffects of hypoxia on proliferation of PASMCs and AASMCs. a and b Hypoxia promoted the proliferation of PASMCs, c and d Hypoxia had no significant effect on the proliferation of AASMCs. Direct cell counting was performed in a and c, MTT assay was performed in b and d. The growth of PASMCs or AASMCs under 21% O2 (control) was set as 100% and the proliferation of treated cells was calculated as a percentage of them. n = 8, Data are means ± S.D. #P < 0.05 or ##P < 0.01 vs. 21% O2,*P < 0.05 or **P < 0.01 vs. 21% O2Back to article page
