OCT-4 expression after treatment with follicle stimulating hormone to bilaterally ovariectomized mice. a, b, c, d. OCT-4 expression was noted prominently in the cytoplasm of epithelial cells whereas small spherical cells expressed nuclear OCT-4. Stromal cells also expressed cytoplasmic OCT-4. Large numbers of spherical stem cells expressing OCT-4 were observed in the glands however the glandular epithelial cells remained negative.
