1 Novel mechanisms in murine nitrofen-induced pulmonary hypoplasia: FGF-10 rescue in culture. nitrofen fibroblast growth factor 10 Mus musculus
2 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. nitrofen fibroblast growth factor 10 Mus musculus
3 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. nitrofen fibroblast growth factor 10 Mus musculus
4 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. nitrofen fibroblast growth factor 10 Mus musculus
5 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]. nitrofen fibroblast growth factor 10 Mus musculus
6 We conclude that nitrofen inhibits Fgf10 expression, which is essential for lung growth and branching. nitrofen fibroblast growth factor 10 Mus musculus
7 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. nitrofen fibroblast growth factor 10 Mus musculus
8 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. nitrofen fibroblast growth factor 10 Mus musculus
9 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. nitrofen fibroblast growth factor 10 Mus musculus
