Keratin 6 immunohistochemistry of human fetal female reproductive tract development. (A & B) Sagittal sections of the human fetal female reproductive tract at 12 weeks of gestation. Note KRT6 expression in epithelia of the bladder, urethra and basal cells of the vaginal plate. (C) Sagittal section of the human fetal female reproductive tract at 14 weeks of gestation. KRT6 is expressed in stratified epithelia of the cervix, vagina and vaginal plate. (D) Sagittal section of the human fetal female reproductive tract at 18 weeks of gestation. KRT6 is seen in epithelia of the cervical canal, fornix and vagina, but not in the uterine corpus. (E) Sagittal section of the human fetal female reproductive tract at 21 weeks of gestation. (G) Note prominent KRT6 expression in vaginal epithelium and patchy KRT6 expression in the uterine corpus (F).
