Fig. 7From: Downregulation of TTF1 in the rat hypothalamic ARC or AVPV nucleus inhibits Kiss1 and GnRH expression, leading to puberty delayOvary development phenotypes associated with TTF1 expression. Pathological assessment of follicular development was performed by H&E staining in the ARC-infected group a and the AVPV-infected group c. b The number of corpora lutea (CL) in the ARC-infected group was measured at PND35 and PND42. d The number of CL in the AVPV-infected group was detected at PND35 and PND42. Scale bars, 500 μm a and c. The data are presented as the mean ± S.E.M. *P < 0.05, **P < 0.01Back to article page
