Aging also inhibited (subventricular zone) SVZ cell proliferation by decreasing both the number of astrocyte-like type-B (prominin-1+/epidermal growth factor receptor (EGFR)+/nestin+/glial fibrillary acidic protein (GFAP)+ cells) and type-C cells (prominin-1+/EGFR+/nestin−/Mash1+ cells), and not affecting apoptosis, 1 day after stroke. This evidence concerns the gene GFAP and stroke disorder.
