Fig. 1

a PRP-Exos under transmission electron microscopy scanning has a typical “tea tray” morphology. Scale bar = 200 nm. b Nanoparticle tracking analysis detected the average particle size of exosomes. c Western blot identified platelet-rich plasma (PRP) and PRP-Exos surface signature molecules (CD9, CD63, and CD81) and platelet source signature molecules (CD41). d Identification of characteristic expression of TSPCs by immunofluorescence staining. Scale bar = 200 μm. e PKH67 staining to identify the endocytosis of PRP-Exos by TSPCs. Scale bar = 40 μm.
