MSC-EVs increase neuronal and vessel densities 1 week after HI. Neuronal (A), vessel (B), and oligodendrocyte (C) densities were analyzed via immunohistochemistry for NeuN, CD31, and Olig2, respectively. Analysis was carried out in stitched large scale confocal images of the striatum obtained from brain sections of 16-day-old C57BL/6 mice that were exposed to HI on postnatal day 9. Vehicle (0.9% NaCl, Veh) and MSC-EVs were administered i.p. 24, 72, and 120 h after HI. White squares in large scale representative images (scale bar: 500 μm) indicate the location of high resolution images (scale bar: 50 μm) shown below. Cellular densities were quantified by unbiased automated software-based object detection. *p < 0.05, n = 12/group.
