Abstract

The application belongs to the technical field of cell culture medium, and in particular relates to a serum-free medium for adipose-derived mesenchymal stem cells and a preparation method thereof, as well as an application of a serum-free medium for adipose-derived mesenchymal stem cells. Wherein, the serum-free medium of adipose-derived mesenchymal stem cells includes basal medium and supplements; wherein, the basal medium comprises DMEM / F12 medium; the supplements include transferrin, recombinant human insulin, fibroblast Cell Growth Factor, Fibronectin, Astragaloside IV, Codonopsis Extract and Aloe Vera Extract. The serum-free medium of this application is used to cultivate adipose-derived mesenchymal stem cells. Through the synergistic effect of various components, it can not only promote the growth and proliferation of adipose-derived stem cells, but also reduce cell damage and improve the survival rate of cells, thereby improving the adipose-derived stem cells. In vitro expansion capability. Moreover, there is no heterologous pollution, no potential safety hazards causing rejection, and the performance of the culture medium is stable and the quality is reliable.

Description

technical field [0001] The application belongs to the technical field of cell culture medium, and in particular relates to a serum-free medium for adipose-derived mesenchymal stem cells and a preparation method thereof, as well as an application of a serum-free medium for adipose-derived mesenchymal stem cells. Background technique [0002] Stem cells are a type of pluripotent cells with self-renewal and multi-directional differentiation capabilities. Mesenchymal stem cells are an important member of the stem cell family, derived from the mesoderm in the early stage of development, and can differentiate into fat, bone, cartilage, muscle, tendon, ligament, nerve, liver, cardiac muscle, Various tissue cells such as endothelium are ideal seed cells for regenerative medicine. Mesenchymal stem cells exist in bone marrow, umbilical cord blood and umbilical cord tissue, placental tissue, adipose tissue and other tissues. When cultured in vitro, it is easy to adhere to the wall an...
