Effects of DEX on the differentiation of stem Leydig cells. Seminiferous tubules were cultured in the LIM in the presence of DEX alone or with RU38486 or RU38486 alone for 21 days, medium testosterone (T) levels were measured (n = 4–8). Panel: (a) DEX (0–100 nM); (b) DEX alone or with RU38486 or RU38486 alone. D100 = DEX 100 nM and R = RU38486 1 μM. The data were presented as the mean ± SEM. Identical letters showed no significant difference between two groups at P < 0.05
