Abstract

The invention discloses a mesenchymal stem cell preparation for treating knee osteoarthritis and a research method thereof. The research method comprises the following steps: preparing a platelet lysate, separating and culturing human umbilical cord MSCs, transplanting the human umbilical cord MSCs and evaluating the curative effect. The invention has the beneficial effects that the activity of prepared cells is ensured, the survival quantity of the cells can be used for experimental research, part of the cells are prevented from remaining in a culture bottle, the accuracy of cell counting is improved, the MSCs treatment is confirmed to be capable of obviously improving the pain of a patient suffering from knee osteoarthritis, and the effect is superior to that of a traditional hyaluronic acid treatment method; according to experimental data, the optimal treatment frequency can be selected, and a scientific basis is provided for treating knee osteoarthritis by using human umbilical cord mesenchymal stem cells in future.

Description

technical field [0001] The invention relates to a research method for a mesenchymal stem cell preparation, in particular to a mesenchymal stem cell preparation for treating knee osteoarthritis and a research method thereof, belonging to the technical field of chemical medicine. Background technique [0002] Osteoarthritis is a chronic bone and joint disease that seriously endangers human health. Cell therapy for osteoarthritis has developed rapidly in recent years and has attracted widespread attention. Umbilical cord-derived mesenchymal stem cells for osteoarthritis have both Mesenchymal stem cells are easy to expand and differentiate, have the advantages of anti-inflammation and recruitment, and have the advantages of cell rejuvenation, large amount of acquisition, no ethical issues, no pain in the process of sampling, high proliferation characteristics, pluripotent differentiation characteristics, and low immunogenicity , No tumorigenicity and other characteristics, it is...
