Stroke induces a multilineage response from adult SVZ. Nestin-CreERT2 :YFP mice were used to fate map nestin+ derivatives following stroke [12]. (A) Confocal images of YFP+ cells that populate the ischemic striatum by 2-weeks following 60 min transient MCAO. Phenotypic fate mapping was performed using markers for migrating neuroblasts (DCX), oligodendrocyte lineage (Olig2) and astrocytes (GFAP). Scale bars = 100 μm (YFP only and YFP/GFAP images), 20 μm (YFP/DCX and YFP/Olig2 images). (B) At 6-weeks post-MCAO, the relative distribution of YFP+ cells within the ischemic brain parenchyma includes approximately 45% astrocytes, 20% oligodendrocyte progenitors (OPCs), 20% neuroblasts and 5% postmitotic neurons.
