OCT-4 expression in the stromal compartment after estrogen (a), progesterone (b, c) and FSH (d, e) treatment to bilaterally ovariectomized mice. Small spherical cells with nuclear OCT-4 were observed in the lumen of blood vessels, among the stromal cells and also among the glandular epithelial cells. Note that endothelial cells lining the blood vessels, stromal cells and glandular epithelial cells majorly express cytoplasmic OCT-4. Few bigger sized cells with nuclear OCT-4 are also evident (red arrow). Scale bar 20 μm
