Bilaterally ovariectomized mouse uterine sections after H&E staining. a-d The cells lining the luminal epithelium and the glands as well as the stromal cells are atrophied in nature with minimal pink stained cytoplasm and high nucleo-cytoplasmic ratio. A careful examination shows the presence of small spherical cells (arrow) and also slightly bigger spherical cells (broken circle). In the luminal epithelium, these small spherical cells are located along the basal region of epithelial cells. Scale bar 20 μm
