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. At higher magnification, nuclear PCNA expression was clearly visualized in cells lodged in the perimetrium. Few single cells along the outer lining were also PCNA positive (arrow). Progesterone treatment resulted in higher expression of PCNA compared to FSH treatment. Whereas cells in the myometrium showed nuclear to cytoplasmic expression of PCNA. Scale bar represents 20 μm
