Abstract

The invention discloses an isolated culture method of human adipose mesenchymal stem cells. The isolated culture method initiatively uses a biopsy needle to create a digestive cavity, and not only removes parenchyma cells (including envelope, connective tissues and the like) on the surface of an adipose tissue block while opening an access (i.e., an entrance of the digestive cavity) by using the biopsy needle, but also enables the digestive cavity to be completely formed in the adipose tissue block, so that enzyme digestive juice is utilized to the utmost extent in the subsequent digestion process, and the pollution caused in the digestion process is tactfully avoided; furthermore, a digestion effect is good, and the problems of dyspepsia and excessive digestion are solved. After the isolated culture method is adopted, the adipose mesenchymal stem cells which are high in purity, motility rate and activity and very low in pollution risk can be obtained, and the cells cultured by the method are good in cell differentiation and high in cell viability, so that the isolated culture method has a greater promotion significance.

Description

technical field

[0001] The invention relates to the technical field of cell culture, in particular to a method for separating and culturing human adipose-derived mesenchymal stem cells. Background technique

[0002] Adipose-derived mesenchymal stem cells are a typical adult stem cell. It has the potential to differentiate into mature adipocytes, chondrocytes, bone cells, tenocytes and skeletal muscle cells. These traits, and their developmental plasticity, have attracted much attention. Adipose-derived mesenchymal stem cells can be used in the field of regenerative medicine to replace and repair degenerated and necrotic tissue cells. Studies have shown that adipose-derived mesenchymal stem cells can differentiate into chondrocytes through the induction of transforming growth factors under serum-free culture conditions. In contrast, adipose-derived mesenchymal stem cells can be differentiated into osteoblasts by adding fatty acids and dexamethasone in the presence of serum...
