Fig. 3 The endometrial effects of different interventions on morphology and ultrastructure. — (A) Representative images of uterine cavities in the HA-GEL transplantation and huMSCs/HA-GEL transplantation groups (the dotted area and the red arrow mark the endometrial area). (B) Representative images of endometrial thickness for ultrasound detection in the HA-GEL transplantation and huMSCs/HA-GEL transplantation groups (the red arrow marks the endometrial echo; the blue area marks the largest cross section of the endometrium). (C) Comparisons of endometrial thickness between the HA-GEL transplantation group and the huMSCs/HA-GEL transplantation group. (D) Representative images of ultrastructural changes in the HA-GEL transplantation and huMSCs/HA-GEL transplantation groups (the left panel shows the surface of epithelial cells; the right panel shows the intercellular changes). ^##P < 0.01 versus 2 months post–HA-GEL, and the results shown are the mean ± SEM of three technical replicates from each animal.
