Treatment of Infertility by Collagen Scaffold Loaded With Umbilical Cord Derived Mesenchyma Stem Cells

Before considering whether patients meet the inclusion criteria, they are diagnosed as intrauterine adhesions with at least one unsuccessful hysteroscopic surgery. And after that there will be history taking, physical examination, ultrasound examination and hysteroscopy examination. If they agree to participate, they will receive separation of adhesions by hysteroscopy surgery and endometrial biopsies, then a collagen scaffold loaded with UC-MSCs will be transplanted into the uterine cavity. The procedure was performed after taking 6 mg/day × 10 days Progynova, continuous administration of the same dosage Progynova for 30 days and 60mg of progesterone were injected on the 30th day post-operation. Postoperative observation including ultrasound examination once a month for 3 times and hysteroscopy after 3 months.
