SELP and Stroke: Importantly, coomassie brilliant blue staining and Western Blot results showed PLTs membrane-related surface proteins including CD62p and CD41 were still displayed in RGD-PLT@PLGA-FE nanoparticles (Fig. 1F and G) and no significantly difference among the three groups (Fig. 1H and I), warranting further investigation for their targeting and therapeutic role in stroke.
