KRT8 (A-C) and KRT7 (D-F) immunostaining in an intact human fetal reproductive tract grown for 4 weeks in an untreated ovariectomized female athymic mouse host. The specimens come from 13-week (A-C & F [AC121]) and 14-week fetuses (D-E [AC159]). In truly stratified epithelium (presumptive exocervix and vagina) the basal epithelial cells (arrowheads) are unstained. KRT7 & KRT8 is expressed in single layered epithelium or apical epithelial cells of multilayered epithelia. Vg. Plate=vaginal plate.
