MSCs alleviate acute lung injury by inducing tolerant DCs. a, b The percentage of lung cDCs (CD11c⁺CD11b⁺ DCs) in the DMSO, DAPT, MSC + DMSO, and MSC + DAPT groups. c The expression of MHCII and CD86 in lung cDCs in the DMSO, DAPT, MSC + DMSO, and MSC + DAPT groups. d, e Histopathological features of lung (hematoxylin and eosin staining; magnification, ×200) and lung injury score in the DMSO, DAPT, MSC + DMSO, and MSC + DAPT groups. f The ratio of lung wet weight to body weight (LWW/BW) in the DMSO, DAPT, MSC + DMSO, and MSC + DAPT groups. The data are presented as the mean ± SD. *p < 0.05 vs. the MSC + DMSO group
