Abstract

The invention discloses application and a method for promoting adipose-derived mesenchymal stem cell proliferation and chondrogenic differentiation by b-D-Glucopyranoside. The method comprises the following steps: S1, acquiring primary adipose-derived mesenchymal stem cells; S2, culturing the primary adipose-derived mesenchymal stem cells in vitro; S3, promoting proliferation: digesting second-generation full adipose-derived mesenchymal stem cell with 0.25% trypsin, when the cells grow and the fusion degree reaches 80%, adding 10ng/mL eucommia ulmoides glycoside into the basic culture medium, and continuously culturing in a 5% CO2 incubator at 37 DEG C for 24 hours; S4, promoting chondrogenic differentiation: taking second-generation full adipose-derived mesenchymal stem cells, digesting the adipose-derived mesenchymal stem cell with 0.25% trypsin, adding 10 ng/mL of b-D-Glucopyranoside, 10 ng/mL of TGF-beta3, 100 nmol/L of dexamethasone, 1% of ITS-G, 50 [mu] g/mL of vitamin C and 40 [mu] g/mL of proline into a basic culture medium, changing the liquid once every 2 days, and continuously performingculturing for 14 days. According to the method, proliferation and chondrogenic differentiation of the adipose-derived stem cells are promoted, meanwhile, the cost can be reduced, and the safety is good.

Description

technical field [0001] The invention belongs to the technical field of stem cells, and in particular relates to the application and method of Eucommia glucoside for promoting the proliferation and chondrogenic differentiation of adipose mesenchymal stem cells. Background technique [0002] In recent years, with the in-depth research on adipose-derived mesenchymal stem cells, its prospects in the treatment of knee osteoarthritis have become more prominent. Promoting the proliferation of adipose-derived mesenchymal stem cells and improving their chondrogenic differentiation ability has always been a research hotspot and difficulty. In previous studies, some chemical substances and cytokines were often used to promote the proliferation and chondrogenic differentiation of adipose-derived mesenchymal stem cells, but they could not be widely used in clinical practice due to high price and safety issues. Contents of the invention [0003] Aiming at the above-mentioned problems e...
