Protective effects of TCs in ARDS mouse models. a HE staining of mice lung tissue in lungs of control mice (Control), ARDS mice (LPS), ARDS mice treated with TCs supernatant (LPS/TC), and ARDS mice treated with miR-21a-3p inhibited TCs supernatant [LPS/TC (miR-21 inhibited)]. b The mRNA expression of inflammatory cytokines in mice lungs in the above four groups. *P < 0.05 vs Control, ^#P < 0.05 vs LPS, **P < 0.05 vs LPS/TCs, n = 6. IL-1β interleukin-1β, IL-6 interleukin-6, TNF-α tumour necrosis factor-α
