Outcomes
Primary Outcome Measures
Incidence of different Adverse Events of transplantation of mesenchymal cells from human embryonic stem cells
Adverse events (AE), severe adverse events (SAE), and treatment-related adverse events (TEAE) occurred within 48 weeks after surgery.
Secondary Outcome Measures
Normal recovery rate of endometrial thickness
Normal recovery rate of endometrial thickness at 1 and 2 months after surgery will be measured (effective rate = endometrium > 6mm after surgery/all participants ×100%).
recurrence rate of intrauterine adhesions
Recurrence rate of intrauterine adhesions (defined as patients with recurrence of intrauterine adhesions reviewed by hysteroscopy at 1 month/total patients ×100%) will be measured.
Intrauterine adhesions score
Intrauterine adhesions score will be measured according to the American Fertility Society in 1988 diagnostic criteria for intrauterine adhesions.The scores range from 1 to 12. Higher scores mean a worse outcome.
The endometrial biopsies for CD31
Immunohistochemical results of CD31 during the two endometrial biopsies will be measured.
Menstrual volume change
Menstrual volume change will be assessed according to menstrual blood loss chart.
Clinical pregnancy rate
Clinical pregnancy rate, abortion rate, live birth rate, and sustained pregnancy rate (defined as live pregnancy over 12 weeks) will be assessed.
The endometrial biopsies for estrogen
Estrogen receptor levels during the two endometrial biopsies will be measured.
The endometrial biopsies for Ki67
Ki67 expression levels during the two endometrial biopsies will be measured.
