Cerebrovascular anatomy and basic physiology is unchanged in KLF2-deficient and KLF2 overexpressing mice. A: India ink staining of brains from KLF2-deficient (K2−/−), control, and KLF2 overexpressing (K2tg) mice. Representative results shown (n = 4 to 5/group). B: assessment of mean arterial blood pressure (BP), heart rate (HR), pH, pCO2, and pO2 in K2−/−, K2tg, and control mice (n = 4 to 5/group). P = nonsignificant for statistical comparisons between all groups. Bpm, beats/min.
