Effect of Preterm Birth on Hypoxia-Inducible Factors and Vascular Endothelial Growth Factor in Primate Lungs

Abstract excerpt

Diminished vascular and alveolar development is characteristic of bronchopulmonary dysplasia (BPD). The low fetal O(2) tension promotes angiogenic responses during ontogenesis, while preterm birth interrupts normal lung growth. Most of the angiogenic responses are governed by hypoxia-inducible factors (HIFs), the expressions of which are unknown in the lungs of preterm primates. Lung tissue was harvested from...
