Immuno-localization of proliferation marker PCNA after treatment with estradiol (a-c). PCNA expression was also noted after estrogen treatment in cells present in both the perimetrium and myometrium. Single cells lining the perimetrium were prominent and expressed PCNA. Small blood capillaries were observed at the junction of peri- and myometrium (lacking in atrophied endometrium, Fig. 1). 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
