Establishment exosome sustain-released system with fibrin on Ta surface. (A) the morphology of exosomes on Ta surface observed by SEM; (B) the exosomes adsorption on Ta surface with different exosome concentration; (C) the morphology of fibrin on Ta surface observed by SEM; (D) the uptake of exosome (green) by BMSCs(blue) observed by LCSM; (E) the semi-quantitative analysis of exosomes in BMSCs; (F) the morphology of fibrin and exosome on Ta surface observed by SEM; (G) the exosome release on Ta surface with fibrin. (a. p < 0.05, compare with 0; b. p < 0.05, compare with 0.1 μg/μL; c. p < 0.05, compare with 0.5 μg/μL; ns. no significances).
