From: Very small embryonic-like stem cells (VSELs) in adult mouse uterine perimetrium and myometrium
Immuno-localization of PCNA after treatment with progesterone (a–b) and (c–d) follicle stimulating hormone. PCNA expression was observed in both P and FSH treated mouse perimetrium but was more in P treated sections compared to after FSH treatment. Cells in both perimetrium and myometrium showed positive expression. Note the development of small blood vessels (asterix) lined by a single layer of endothelial cells at peri- and myometrium junction. Excessive non-specific brown color in A is because of endogenous mouse Ig staining since PCNA antibody is monoclonal antibody being used on mouse sections. Scale bar represents 20 μm
