RBFOX3 and stroke disorder: Our result is different from other reports [30,31], but is partly consistent with a previous study, which demonstrated that EPO increased the number of BrdU+/NeuN+ double-labeled cells in the ischemic hemisphere 14 days after stroke, whereas there were only a few BrdU+/GFAP+ positive cells, suggesting that EPO promoted progenitor differentiation towards a neuronal lineage [32].
