Ovary 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 < 0.01
