The possibility that FGF10, via PPAR-γ signaling, can drive reinforcement of the lipogenic phenotype at the expense of the myogenic phenotype raises the potential that FGF10-based therapies could be beneficial in combating idiopathic pulmonary fibrosis (IPF) and/or COVID-19 related pulmonary fibrosis. Here, FGF10 is linked to idiopathic pulmonary fibrosis.
