- the neural differentiation medium was replaced every other day, and the amount of the change was half of the original medium.
- an in vitro fraction of the induced neural stem cells was obtained.
- the expression of Tuj, Map2, Dcx, TH, GABA, Glutamine and GFAP proteins in in vitro differentiation of induced neural stem cells obtained by immunofluorescence detection is shown in Fig. 6.
- TH, GABA, Glutamine and GFAP proteins are markers of different types of neurons and glial cells, respectively, thereby being able to detect Tuj, Map2, Dcx, TH, GABA, in vitro differentiation of induced neural stem cells,
- the expression of Glutamine and GFAP proteins can be used to identify different types of neurons and glial cells obtained by in vitro differentiation of induced neural stem cells, thereby confirming the in vitro differentiation ability of iNSC.
