Fig. 1From: Exosomes derived from atorvastatin-pretreated MSC accelerate diabetic wound repair by enhancing angiogenesis via AKT/eNOS pathwayThe characterization of BMSC-derived exosomes. a The morphology of Exos and ATV-Exos was examined by TEM. b The specific surface markers (Alix, TSG101, CD81) of Exos and ATV-Exos were assessed by Western blotting. c The diameter and particle concentration of Exos and ATV-Exos were detected via NTA. d The uptake verification of Exos and ATV-Exos by HUVEC via laser scanning confocal microscopy. Exosomes, cytoskeleton, and cell nucleus were stained red, green, and blue, respectivelyBack to article page
