Intrauterine adhesions (IUA) is a group of diseases caused by endometrial injury leading to occlusion of the uterine cavity and serious abnormality of the uterine cavity morphology, which causes primary or secondary infertility by affecting embryo implantation. At present, the poor effectiveness of clinical treatment methods has made the thin endometrium after intrauterine adhesions an urgent problem to be solved in the clinical field of assisted reproduction. Stem cells with multi-directional differentiation potential provide a new idea for the treatment of cervical adhesions. However, due to limitations such as stem cell extraction, technical conditions, and ethical issues, clinical application cannot be widely carried out. Exosomes are vesicle structures produced by paracrine secretion of cells, containing abundant proteins, RNA, etc., and mediating information exchange between cells. Recent studies have found that stem cells play a role in tissue repair mainly through paracrine, and stem cell-derived exosomes have similar functions to stem cells. Human cord mesenchymal stem cells were selected as an intervention for this clinical study because of their wide source, easy access, and low immunogenicity. Therefore, in this clinical study, the investigator will evaluate the clinical safety and efficacy of infusing human umbilical cord mesenchymal stem cell exosomes into the uterine cavity for the treatment of thin endometrium after intrauterine adhesions.
