Aging also inhibited migration of neuroblasts (DCX+ cells), as indicated by an accumulation of neuroblasts at migratory zones 14 days after injury; consistently, aged mice presented a smaller number of differentiated interneurons (NeuN+/BrdU+ and GAD67+ cells) in the peri-infarct cortical area 14 days after stroke. Here, RBFOX3 is linked to stroke disorder.
