hAECs facilitated endometrial recovery in the IUA mouse model. A IHC staining of vWF reflected the MVD of the endometrium. The microvessels, which were vWF-positive, are indicated by arrows in the figure. MVD was reduced in the IUA group and increased in the hAEC-treated group. B IHC staining showed that the expression of VEGF was higher in the hAEC-treated group than in the IUA group. C The expression of PCNA decreased in the IUA group and reached almost normal levels in the hAEC-treated group. a–c, scale bar = 100 μm; d–f, scale bar = 50 μm
