Abstract

The invention discloses a neural stem cell induction differentiation medium and a neural stem cell induction differentiation method. Specifically, the neural stem cell induction differentiation mediumcomprises a basic medium and additives. The basic medium is a DMEM / F12 medium. The additives include 1-5mM glutamine, a 2-8microM GSK-3 inhibitor, a 2-10microM BMP inhibitor, a 2-10microM ALK inhibitor, 0.5%-2% of a cell culture additive and 0.5%-2% of a double-antibody. The neural stem cell induction differentiation medium provided by the invention has the characteristics of clear and simple components, high differentiation efficiency, short differentiation time, no animal-derived component, no need for animal-derived cells to serve as the feeder layer during differentiation, no need to formEB, and no need for repeated replacement of the culture solution components in differentiation, and can acquire a large number of high purity neural stem cells within a short time.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a neural stem cell induction differentiation medium and a neural stem cell induction differentiation method. Background technique [0002] In 2006 and 2007, Japanese scholar Shinya Yamanaka successfully introduced four transcription factors (Oct4, Sox2, Klf4 and c-Myc) into mice respectively (Takahashi and Yamanaka., 2006). and human (Takahashi et al., 2007) skin fibroblasts were reprogrammed into induced pluripotent stem cells (Induced Pluripotent Stem Cells, iPSCs), and thus won the 2012 Nobel Prize in Medicine and Physiology. hiPS cells (human induced pluripotent stem cells) have all the differentiation capabilities of hES cells (human embryonic stem cells) and have no ethical issues. They will completely replace hES cells in the near future and become the most important cell source for regenerative medicine. [0003] Neuroscience research includes the whole process of it...
