Transient Redirection of SVZ Stem Cells to Oligodendrogenesis by FGFR3 Activation Promotes Remyelination.

ABSTRACT: Stimulating oligodendrocyte (OL) production from endogenous progenitor cells is an important strategy for myelin repair and functional restoration after disease or injury-induced demyelination. Subventricular zone (SVZ) stem cells are multipotential, generating neurons and oligodendroglia. The factors that regulate the fate of these stem cells are poorly defined. In this study, we show that genetically increasing fibroblast growth factor receptor-3 (FGFR3) activity in adult SVZ stem cells transiently and dramatically redirects their differentiation from the neuronal to the oligodendroglial lineage after pathological demyelination. The increased SVZ-derived oligodendrogenesis leads to improved OL regeneration and myelin repair, not only in the corpus callosum (a normal destination for SVZ-d
