From: Very small embryonic-like stem cells (VSELs) in adult mouse uterine perimetrium and myometrium
Bilaterally ovariectomized mouse uterine sections after H&E staining and expression of PCNA and OCT-4. a Myometrium and perimetrium surrounding the inner endometrium were clearly visualized. They comprised of two distinct layers including outer perimetrium and the inner myometrium. b At higher magnification, myometrium comprised rounded cells (arrow) as well as sparsely distributed stromal cells. c No expression of PCNA was observed whereas (d) Nuclear OCT-4A expression (arrow) was clearly evident in both perimetrium and myometrium in atrophied uterine sections. Scale bar represents 20 μm
