Pulmonary histology. Lungs from Hif1a^+/+ (a and c) and Hif1a^+/+ (b and d) mice exposed to 21% (a and b) or 10% (c and d) _O for 3 weeks were formalin-fixed, paraffin-embedded, sectioned, and stained with hematoxylin and eosin for videomicroscopy. Each field shows a representative pulmonary arteriole. ×400.
