The 50/10 Oxygen-Induced Retinopathy Model Serves as a Hyperoxia and Hypoxia Model of Bronchopulmonary Dysplasia

Alveolar changes observed by hematoxylin and eosin staining, prolonged and stronger α-SMA expression and augmented collagen accumulation resemble the histopathology of BPD, suggesting that the rat 50/10 OIR model is suitable for use in BPD research.
