Fig. 6: PRL and apoptosis of NPCs in vivo

a TUNEL staining and staining of cleaved caspase 3 in the NP in vivo. b Semi-quantification of apoptotic index and quantification of cleaved caspase 3 staining on days 7 and 14 after initial puncture. Scar bar = 50 μm. ^*P < 0.05 vs. the control group, ^#P < 0.05 vs. the vehicle group
