Fig. 1From: Hypoxic hUCMSC-derived extracellular vesicles attenuate allergic airway inflammation and airway remodeling in chronic asthma miceCharacterization of Nor-EVs and Hypo-EVs. a Transmission electron micrographs of Nor-EVs and Hypo-EVs. Scale bar = 200 nm. b Western blot analysis of TSG101 and HSP60 expression in Nor-EVs and Hypo-EVs (n = 3). Ponceau S staining served as a loading control. c NTA analysis of Nor-EVs and Hypo-EVs revealed that EVs from the two groups exhibit similar size ranges (n = 3). d NTA counted the production of EVs derived from normoxia-cultured hUCMSCs (Nor-MSC) and EVs from hypoxia-treated hUCMSCs (Hypo-MSC) (n = 3). ***P < 0.001Back to article page
