摘要: Vascular endothelial growth factor (VEGF) is a potent cell mitogen involved in normal and abnormal angiogenesis. VEGF mRNA protein are abundant distal epithelium of midtrimester human fetal lung. In the present study, we identified immunoreactivity for KDR, major VEGF-specific receptor, lung epithelial cells tissue, suggesting possible autocrine or paracrine regulatory role pulmonary differentiation. Addition exogenous to explants resulted increased volume density lumen tissues, both morphometric parameters tissue Cellular proliferation demonstrated by bromodeoxyuridine uptake was prominent airway VEGF-treated explants. also surfactant (SP) A mRNA, SP-C SP-A levels compared with controls. However, SP-B were unaffected treatment. [(3)H]choline incorporation into total phosphatidylcholine treatment, but disaturated not affected VEGF. Based on these observations, conclude that may be an important developing
