To investigate the potential therapeutic effects of NPNT overexpression in the alveolar epithelium on experimental pulmonary fibrosis, we generated mice with conditional overexpression of NPNT specifically in AT2 cells by crossing NPNT‐fl/fl mice with Sftpc‐Cre mice (Figure S2D–F, Supporting Information). The gene discussed is SFTPC; the disease is pulmonary fibrosis.
