VSELs survive ovariectomy in uterine endometrium. Left panel: Atrophied endometrium after bilateral ovariectomy showed the presence of small spherical cells (VSELs, arrows). Right panel: Minimal PCNA expression was noted in ovariectomized uterine sections in small spherical cells in the epithelial layer (upper panel). OCT-4 expression was noted in both the cytoplasm and nuclei of small spherical cells (lower panel) [68]. Scale: 20 μm
