SMC‐specific Jak2 deficiency improved the reaction of pulmonary blood vessels to hypoxic condition. RVSP (A), RV/(LV + S) ratio (B), PAT/PT ratio (C), mean systemic arterial BP (D), ejection fraction (E), fractional shortening (F) and body weight change ratio (G) in Jak2‐C and Jak2‐CKO mice after exposure to normoxic (n = 8 per group) or hypoxic (n = 10 per group) conditions for 28 days. The data are represented as the mean ± SEM. **P < .01. RVSP, right ventricular systolic pressure; RV/ (LV+S), the right ventricle/left ventricle plus septum; PAT/PT, pulmonary acceleration time/pulmonary ejection time
