Small Extracellular Vesicles Secreted by iPSC-Derived MSCs Ameliorate Pulmonary Inflammation and Lung Injury Induced by Sepsis through Delivery of miR-125b-5p

Figure 3

iMSC-sEV ameliorated AMs inflammatory response and inhibited the NF-κB signaling pathway activation induced by LPS in vitro. (a) Pro-inflammatory cytokines IL-1β, TNF-α, and IL-6 levels in the supernatant of AMs treated with iMSC-sEV. (b) Representative western blot and quantitative analysis of p-p65 and p65 in recipient AMs treated with iMSC-sEV. (c) Detection of the uptake effects of AMs on PKH-67-labelled iMSC-sEV by means of fluorescent microscopy. Data presented as mean ± SD. , compared within two groups. n = 3 per group.
