Fig. 4From: Delayed and repeated intranasal delivery of bone marrow stromal cells increases regeneration and functional recovery after ischemic stroke in miceIntranasally delivered BMSCs migrated to the peri-infarct region of the ischemic brain. A–C Brain sections at the stroke penumbra region were collected and analyzed to examine cell presence of BMSCs delivered intranasally. Hoescht-positive BMSCs (blue) counterstained with Propidium Iodide (PI, red) were detected in the peri-infarct area of the cortex at 6 and 24 h after BMSC delivery at 3 days after stroke. Scale bars = 20 μm. D An illustration of the mouse ischemic brain where the cells were found in the cortexBack to article page
