Abstract

The invention provides a preparation containing endometrium mesenchymal cell exosome, and relates to the technical field of biological stem cells. The preparation comprises, by volume, 5 parts of endometrium mesenchymal cell exosome and 95 parts of matrix solution. The matrix solution comprises 95-99 parts of multiple electrolytes injection liquid and 1-5 parts of medicinal human blood albumin, and endometrium mesenchymal cell exosome is derived from starvation culture of autologous endometrium mesenchymal cells, and the time of the starvation culture is 12-24 hours. The autologous endometriummesenchymal cells are extracted from the mesenchymal stem cells in a human endometrium and cultured by using a normal culture method. The culture time is 48-72 hours. The invention provides a medicine which is safe, effective and convenient to use for treating diseases such as endometrial damage and the like.

Description

Technical field [0001] The invention relates to the technical field of biological stem cells, in particular to a preparation containing autologous endometrial mesenchymal stem cell exosomes. Background technique [0002] The uterus is very important to a woman's life, but once the endometrium is damaged, it will cause a series of consequences. The existing endometrium is difficult to repair and the treatment time is long, which brings great troubles to many women. [0003] Mesenchymal Stem Cells (MSC) Mesenchymal Stem Cells are pluripotent stem cells, which have multiple functions such as multidirectional differentiation, hematopoietic support and promotion of stem cell implantation, and immune regulation. They are mainly found in the endometrium, fat and bone marrow. in. [0004] Therefore, how to enable mesenchymal stem cells to be used to treat endometrial injury has become an urgent problem for those skilled in the art. Summary of the invention [0005] The technical problem to ...
