We evaluated the role of the key pulmonary morphogenetic gene fibroblast growth factor-10 (Fgf10) in murine nitrofen-induced primary lung hypoplasia, which is evident before the time of diaphragm closure. In situ hybridization and competitive RT-PCR revealed a profound disturbance in the temporospatial pattern as well as a 10-fold decrease in mRNA expression level of Fgf10 but not of the inducible inhibitor murine Sprouty2 (mSpry2) after nitrofen treatment. Exogenous FGF-10 increased branching not only of control lungs [13% (right) and 27% (left); P < 0.01] but also of nitrofen-exposed lungs [23% (right) and 77% (left); P < 0.01]. Expression of mSpry2 increased 10-fold with FGF-10 in both nitrofen-treated and control lungs, indicating intact downstream FGF signaling mechanisms after nitrofen treatment. We conclude that nitrofen inhibits Fgf10 expression, which is essential for lung growth and branching. Exogenous FGF-10 not only stimulates FGF signaling, marked by increased mSpry2 expression, in both nitrofen-treated and control lungs but also substantially rescues nitrofen-induced lung hypoplasia in culture.
