Abstract

The invention discloses a culture medium for culturing neural stem cells on the basis of peripheral blood mononuclear cells. The culture medium comprises components as follows: a DMEM/F12 culture medium and a neurobasal medium in a volume ratio being 1:0.8-1.2 as well as an adenylate cyclase activator, a serum substitute, L-ascorbic acid, an L-glutamine derivative, an ALK inhibitor, a GSK-3 inhibitor, an ALK-2,3,6,AMPK inhibitor and an ALK-4,5,7 inhibitor. The invention further discloses a method for culturing the neural stem cells on the basis of the peripheral blood mononuclear cells. With adoption of the culture medium, the neural stem cells can be obtained from the peripheral blood mononuclear cells as the raw material through directional differentiation culture, materials are taken conveniently and free of quantitative restriction, and moral controversy can be avoided.

Description

technical field [0001] The invention belongs to the technical field of neural stem cell culture, and in particular relates to a culture medium and a culture method of neural stem cells. Background technique [0002] Neural stem cells (NSCs) are a kind of mother cells with division potential and self-renewal ability, which can produce various types of cells in nervous tissue through asymmetric division, including neurons, oligodendrocytes and astrocytes. The use of transdifferentiation technology can achieve NSCs proliferation, self-renewal and multidirectional differentiation in vitro. However, a small amount of NSCs isolated from the human body (such as the central nervous system) can be differentiated into corresponding NSCs under the influence of the microenvironment in the body after being transplanted into the human body through proliferation to a certain concentration and standard, so that the damaged nerve function can be repaired. , and the implanted NSCs can migrat...
