Beschreibung
Zusammenfassung:	The invention relates to a spinal cord OLIG2 nerve progenitor cell induction and self-renewal culture system, an induction method and application. The culture system comprises a basic culture medium, an induced differentiation factor and an in-vitro maintenance factor, wherein the induced differentiation factor and the in-vitro maintenance factor are combined with the basic culture medium for use; the induced differentiation factor at least comprises a 0.01-50 microns of GSK3 inhibitor, a 0.01-500 microns of TGF beta inhibitor and a 0.01-500 microns of BMP inhibitor; and the in-vitro maintenance factor comprises a 0.01-50 microns of GSK3 inhibitor, a 0.01-500 microns of TGF beta inhibitor, 0.01-5000 ng/mL of Sonic Hedgehog, a 0.01-20 microns of Smoothened agonist, a 0.01-500ng/mL of LEGF family growth factor, a 0.01-500 ng/mL of FGF family growth factor, a 0.01-500 microns of BMP inhibitor, a 0.01-50 microns of JAK1/2 inhibitor, a 0.01-10000nM of Src kinase inhibitor and a 0.01-50 microns of RetinoicAcid.
