Figure 1. Internal diameters and spontaneous tone in GM feed arteries and arterioles are similar for young and old mice .

Figure 1

Resting diameter (A) and maximal diameter (B) decreased as vessel branch order increased for both age groups (FA>1A>2A.3A). Spontaneous tone (C; see Methods) increased with vessel branch order. Summary data are means ± SEM, n = 6 per age group. # P < 0.05, main effect of age. Δ P < 0.05, main effect of vessel branch order; * P < 0.05, old vs. young mice for designated branch order.
