Abstract
This invention relates to a method for amplifying neural stem cells in vitro by 3-dimensional culture. The method comprises: selecting microcarrier with 3-dimensional environment, pre-treating, coating the microcarrier with 40-60 ng/mL alkaline fibroblast growth factor, 40-60 ng/mL epidermal growth factor, and B27 DMEM/F12 neural stem cell serum-free culture medium, adding 1X105-1X106 neural stem cells into the culture bottle, taking out the microcarrier grown with neural stem cells, removing the microcarrier, and rinsing cells to obtain neural stem cells. The porous microcarrier can enlarge the culture area. The alkaline fibroblast growth factor and epidermal growth factor can promote cell multiple fission and improve cell microenvironment, which is advantageous for multiple fission of neural stem cells.
