| Outline of Final Research Achievements |
NG2 cells are oligodendrocyte progenitor cells in the adult brain, but they differentiate into astrocytes(AS) as well in the embryonic ventral telencephalon.
In order to analyze the molecular mechanism of NG2 cells differentiation into AS, we analyzed NG2 cell differentiation in Nkx2.1 KO mice that is an essential transcription factor for ventral telencephalic development. We found that differentiation of NG2 cells into AS was not changed in Nkx2.1 KO mice. Moreover, we performed slice transplant assay to identify the AS generating NG2 cells. We found that cells in lateral ganglionic eminence (LGE) that is located dorsal to Nkx2.1-expressing area are the source of NG2-derived AS. We are now analyzing the molecular mechanisms that regulate AS generation from LGE-derived NG2 cells.
