Inter-group differences of the normal follicles after transplantation. A Morphological examination of fresh tissue, blue arrows indicate morphologically intact primary follicles. B Abundant vascular generation observed 4 weeks after transplantation. C Multilevel follicles observed 4 weeks after transplantation, with black arrows indicating secondary follicles and blue arrows indicating primary follicles. D and E Follicles’ development in the tissue after 6 weeks of transplantation, with red arrows indicating normal secondary follicles, yellow arrow indicating apoptotic follicle. F Comparison of the proportions of normal morphological follicles among different groups
