The effect of mMSCs overexpressing TGFβ1 on the differentiation of CD4⁺ T cells in the lungs of ARDS mice at 7 days after mMSCs transplantation. a–d The differentiation of Th17 and Treg in the lungs of LPS-induced ARDS mice was detected by flow cytometry (n = 3, *p < 0.05 compared with the control group; ^#p < 0.05 compared with the ARDS group; ^δp < 0.05 compared with the LPS + mBM-MSC-NC group). e Representative flow cytometry analysis was shown for each treatment group. ARDS, acute respiratory distress syndrome; mMSCs, mouse mesenchymal stem cells; NC, normal control
