Problems solved by technology

The existing umbilical cord mesenchymal stem cells have been widely used in a large number of animal models and clinical studies, but the therapeutic effects on rheumatoid arthritis are uneven. The key lies in the difficulty of controlling the activity of umbilical cord mesenchymal stem cells. The mesenchymal stem cells in the preservation medium of the injection are prone to adhesion, aggregation, and poor stability, which affects the curative effect of the existing human umbilical cord mesenchymal stem cell injection in anti-rheumatoid arthritis

Abstract

The invention provides an anti-rheumatoid arthritis human umbilical cord mesenchymal stem cell injection and a preparation method thereof. Every 100ml of the umbilical cord mesenchymal stem cell injection comprises: 4-6*10<5> human umbilical cord mesenchymal stem cells, 2-4g of human serum albumin, 10-30mg of Chinese yam polysaccharide, 60-90mg of compound amino acid, 0.5-0.6g of sodium chloride,0.5-0.6g of sodium gluconate, 0.3-0.4g of sodium acetate, 0.03-0.04g of potassium chloride and 0.03-0.04g of magnesium chloride. The human umbilical cord mesenchymal stem cell injection special for resisting rheumatoid arthritis prepared by the invention can effectively maintain the activity of umbilical cord mesenchymal stem cells, has good stability, also can effectively stop inflammatory mediator release, alleviates inflammatory cell infiltration degree, significantly reduces pannus number, and has good repair effect on rheumatoid arthritis bone and cartilage damage, thus having broad application prospects.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to an anti-rheumatoid arthritis human umbilical cord mesenchymal stem cell injection and a preparation method thereof. Background technique [0002] Current clinical studies have shown that mesenchymal stem cells can not only reduce the incidence of arthritis and reduce the severity of experimental arthritis through immune regulation, but also repair the bone and cartilage damage that occurs in rheumatoid arthritis, which indicates that It has broad prospects for the treatment of rheumatoid arthritis. Since the successful isolation of mesenchymal stem cells from human umbilical cord Wharton's jelly in 2003, the umbilical cord has become another biological tissue rich in mesenchymal stem cells after bone marrow and fat. It has the advantages of low immunogenicity and low immunogenicity, and has the conditions for industrialization and clinical use. The existing umbilical cord m...
