Figure 5: Grafted cells were detected by immunochemistry against human antigens. (A) Human specific nuclei antigen expression was negative in recipient ovaries without hAECs transplantation. (B) Human nuclei antigen was not detected in some recipient ovaries 2 month following hAECs transplantation. (C, D) Human nuclei antigen was expressed in antral follicles in recipient ovaries 2 months after hAECs transplantation. (E) Human FSHR was not detected in recipient ovaries without hAECs transplantation. (F) Human FSHR was not detected in some recipient ovaries 2 months following hAECs transplantation. (G, H) Human FSHR were detected in recipient ovaries 2 months following hAECs transplantation. Arrows indicated human antigens expression in granulosa cells around the ovum, while the other granulosa cells were negative control. Scale bars=100 μm.
