The effect of EPO on vWF-staining vascular structure in the injured cortex and ipsilateral hippocampus 90 days after TBI (a, b). EPO treatment significantly increased vasculature (brown-stained vessels, arrows as example) in the injured brain after TBI compared to the saline-treated group (a). The number of vWF-stained vasculature is shown in (b). Data represent mean ± SD. Scale bar = 50 μm (a). N (rats/group) = 7 (Saline); 8 (EPO-6 h); 8 (EPO-24 h).
