Development of polycythemia in mice subjected to chronic hypoxia. Hematocrits of Hif1a+/+ (open bars) and Hif1a+/– (closed bars) mice exposed to room air or 10% O2 for 1–6 weeks were determined. Results are expressed as mean ± SE (n = 8–10 mice for 0–5 weeks; n = 5–7 mice for 6 weeks). ANOVA with a post hoc Dunnet's test revealed a significant difference between genotypes (P = 0.025).
