Fig. 4From: Human bone marrow mesenchymal stem cell-derived extracellular vesicles attenuate neuroinflammation evoked by focal brain injury in ratsExtracellular vesicles (EVs) derived from human bone marrow mesenchymal cells (hBM-MSCs) enter the ipsilateral hemisphere of focal injured rats after intra-arterial infusion. Representative images of EVs labeled with PKH26 visible in the different regions of ipsilateral hemisphere of graft recipients 24 h after EV transplantation (a-c). Scale bar 10 μmBack to article page
