RIPK1 and acute respiratory distress syndrome: Notably, we found that the mRNA expression of Xiap, Bax, Ripk1, Casp8 and Casp3 in the lineage‐labelled AECs was significantly reduced after FGF10 treatment compared with PBS‐treated controls (Figure 3B,C), suggesting that FGF10 may attenuate lung injury by regulating apoptosis or pyroptosis in ALI.
