DCX and Stroke: The number of DCX-positive migrating neuroblasts in the lateral ventricle area and hippocampal region of stroke-affected hemispheres significantly increased after treatment with NBE-MSC-MVs compared to that of PBS (Fig. 3A), suggesting that NBE-MSC-MVs potentially promote neurogenesis by neural stem cells in the hippocampus and SVZ, and these cells migrate toward the ischemic boundary after stroke.
