Abstract

The invention relates to the field of stem cells, provides a culture medium for promoting osteogenic differentiation of mesenchymal stem cells, and is used for solving the problem of low efficiency ofdifferentiation of stem cells into bone cells. The culture medium for promoting osteogenic differentiation of mesenchymal stem cells provided by the invention comprises 8-12 [mu] g / ml of insulin, 0.05-0.2 [mu] g / ml of transferrin, 0.05-0.2 ng / ml of BMP-4, 5-8 ng / ml of FGF-2, 1-3 ng / ml of growth hormone, 100-150 [mu] g / ml of glutathione, 1-3 mM of L-glutamine, 40-50 [mu] M of beta-mercaptoethanol,1-3 mM of sodium pyruvate, 0.05-0.15 mM of non-essential amino acid, 2-10 [mu] M of nano ferric oxide and the balance of a DMEM culture medium. No biological serum is added into the culture medium, and meanwhile, nano oxide is introduced, so that mesenchymal stem cells can be remarkably promoted to differentiate into bone cells.

Description

technical field [0001] The invention relates to the technical field, in particular to a culture medium for promoting osteogenic differentiation of mesenchymal stem cells. Background technique [0002] Stem cells are a kind of cell type with self-renewal ability and multi-directional differentiation potential. It is the first cell in a series of processes from proliferation, migration, differentiation to maturity of new human cells. Research on stem cells has become one of the most challenging and attractive fields in biology. Stem cells can be divided into embryonic stem cells and adult stem cells according to their sources. Mesenchymal stem cells (MSCs, mesenehymal stem cells) are one of the adult stem cells. As a class of adult stem cells with self-renewal ability, mesenchymal stem cells can differentiate into a variety of cell tissue types. It can not only differentiate into a variety of mesenchymal-derived cell lineages, such as adipocytes, osteoblasts, chondrocytes, ...
