Figure 1.

FOXL2^OE mice displayed thin uterus and stratified uterine epithelium. The representative uterine images of Pgr^cre (A–C) and FOXL2^OE mice (D–F) at PND21 (A and D), 3 M (B and E), and 8 M (C and F). The uteri were much thinner in FOXL2^OE mice compared with Pgr^cre mice at 3 M and 6 M. Basal cell marker, P63, staining in the uterus of Pgr^cre (G–I) and FOXL2^OE mice (J–O) at PND21 (G, J, and M), 3 M (H, K, and N), and 6 M (I, L, and O). P63 positive basal cells in the uterus indicate epithelium stratification. They were found at the basal side of some luminal epithelium (J–L) and some glandular cells (M–O) in the FOXL2^oe uterus. PND: postnatal day; M: months old. Arrow indicates stratified epithelium. N = 3 for each genotype and age group. Arrow in A–F refers one uterine horn. Arrow in J–O indicates stratified epithelium.
