Effect of U0126 or rapamycin on VIP-induced follicle development. Four-day-old rat ovaries were cultured with (i) 10−7 mol/L VIP, (ii)VIP plus 10−8 mol/L U0126, or (iii) VIP + 8.75×10−8 mol/L rapamycin for three days. (A) HE stained ovaries of different groups: control (a), VIP (b), VIP + U0126 (c), VIP + Rapa (d). (B and C) The numbers of early-growing follicles and primordial follicles were counted, and their ratio was calculated. Scale bar: 50 μm. Values are mean ± s.d. of at least three experiments. (*P < 0.05 compared with the VIP group, & P < 0.05 compared with the VIP + U0126 group, # P < 0.05 compared with the VIP + Rapa group).
