The adult spinal cord harbors a population of GFAP-positive progenitors with limited self-renewal potential

Adult neural stem cells (aNSCs) of the forebrain are GFAP-expressing cells that are intercalated within ependymal cells of the subventricular zone (SVZ). Cells showing NSCs characteristics in vitro can also be isolated from the periaqueductal region in the adult spinal cord (SC), but contradicting results exist concerning their glial versus ependymal identity. We used an induci- ble transgenic mouse line (hGFAP-CreERT2) to conditionally label GFAP-expressing cells in the adult SVZ and SC periaque- duct, and directly and systematically compared their self-renewal and multipotential properties in vitro. We demonstrate that a population of GFAP1 cells that share the morphology and the antigeni…
