Discordant roles for FGF ligands in lung branching morphogenesis between human and mouse.

ABSTRACT: Fibroblast growth factor (FGF) signaling plays an important role in lung organogenesis. Over recent decades, FGF signaling in lung development has been extensively studied in animal models. However, little is known about the expression, localization, and functional roles of FGF ligands during human fetal lung development. Therefore, we aimed to determine the expression and function of several FGF ligands and receptors in human lung development. Using in situ hybridization (ISH) and RNA sequencing, we assessed their expression and distribution in native human fetal lung. Human fetal lung explants were treated with recombinant FGF7, FGF9, or FGF10 in air-liquid interface culture. Explants were analyzed grossly to observe differences in branching pattern as well as at the cellular and molecul
