Abstract

The invention belongs to the technical field of cell culture media, and particularly relates to a serum-free culture medium for adipose-derived stem cells, and a preparation method and application of the serum-free culture medium for the adipose-derived stem cells, wherein the serum-free culture medium for the adipose-derived stem cells comprises a basic culture medium and additives, wherein the basic culture medium comprises a DMEM / F12 culture medium; and the additives comprise transferrin, recombinant human insulin, fibroblast growth factors, fibronectin, astragaloside, a codonopsis pilosula extract and an aloe extract. The serum-free culture medium disclosed by the invention is used for culturing the adipose-derived stem cells; through the synergistic effect of all the components, growth and proliferation of the adipose-derived stem cells can be promoted; cell damage can be reduced; the survival rate of the cells can be increased; and therefore, the in-vitro amplification capacity of the adipose-derived stem cells is improved. Moreover, heterologous pollution is avoided; potential safety hazards causing rejection reaction do not exist; and the culture medium is stable in performance and reliable in quality.

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...
