Tissue localization of CXCL12 protein in human preovulatory follicles. Sections of human follicles were obtained at pre- (A), early (B), and late (C and D) ovulatory phases and immunostained with primary antibodies for CXCL12. Arrows indicate leukocytes expressing CXCL12. Panel D was a magnified image of the box in panel C. Scale bar, 500 μm; Gc, granulosa cell layer; Tc, theca cell layer.
