Serum-free culture medium for mesenchymal stem cells

Abstract

The invention discloses a serum-free culture medium for mesenchymal stem cells. The serum-free culture medium for the mesenchymal stem cells comprises the following ingredients: fibronectin at the final concentration of 25mu g / ml, basic fibroblast growth factors at the final concentration of 10ng / ml, human epidermal growth factors at the final concentration of 15ng / ml, recombinant human insulin at the final concentration of 1mg / ml, human transferrin at the final concentration of 0.55mg / ml, human blood albumin in a volume ratio of 5 percent, sodium selenite at the final concentration of 0.67mug / ml, L-carnitine at the final concentration of 5mM and resveratrol at the final concentration of 30mu M. When the mesenchymal stem cells are cultured by the serum-free culture medium for the mesenchymal stem cells, animal-derived serum is not contained, so infection risks can be controlled; the L-carnitine and the resveratrol which are added into the serum-free culture medium for the mesenchymalstem cells can effectively improve the growth state of the mesenchymal stem cells; and the growth speed of the mesenchymal stem cells is remarkably improved, and the biological characteristics of themesenchymal stem cells are kept unchanged.

Description

technical field

[0001] The invention relates to the technical field of stem cell culture medium, in particular to a serum-free culture medium for mesenchymal stem cells. Background technique

[0002] Mesenchymal Stem Cells (MSCs) are an important member of the stem cell family, derived from the mesoderm and ectoderm in the early stages of development, and have the characteristics of multi-directional differentiation potential, hematopoietic support and promotion of stem cell implantation, immune regulation and self-replication. And increasingly people's attention. Mesenchymal stem cells are widely present in various tissues throughout the body, cultured and expanded in vitro, and can differentiate into cardiomyocytes, nerve cells, and fat cells under specific conditions. With the in-depth research on the biological characteristics and functions of mesenchymal stem cells by scholars at home and abroad, mesenchymal stem cells can be isolated from various tissues.
