TGFB1 and pemphigus foliaceus: In pulmonary fibroblasts, TGF‐β1 could decrease miR‐153 expression, whereas overexpression of miR‐153 attenuated the pro‐fibrogenic activity of TGF‐β1.26 In our present study, hUCMSCs treatment could significantly inhibit TGF‐β1 expression and up‐regulate miR‐153‐3p levels in MGO‐induced PF rats.
