Fig. 3: Measurements of the blood vessel luminal area and wall thickness.

a H&E staining of ovarian sections. Arrow, blood vessel. Scale bar: 1.5 mm. b The number of blood vessels within the ovaries of different groups appeared to be similar. c The luminal area of the blood vessels was increased in the NTx group compared to the normal group but was restored in the Tx group. d The same pattern was also observed for wall thickness. However, the number of blood vessels within the ovarian tissues remained relatively constant. *vs. the normal group (P < 0.05). # vs. the NTx group (P < 0.05). Nor normal group, NTx non-transplantation group, Tx transplantation group.
