A, basal lumen diameter of pressurized UAs (60 mmHg) from NP, P14 and P18 WT (open symbols, same data as shown in Fig. 3
A) or γ1−/− mice (grey symbols). Symbols are individual values; bars are median values. †
P < 0.05 compared to NP of same genotype, #
P < 0.05 compared to P14 of same genotype, *
P < 0.05 compared to WT at same stage. B, 1–100 nm IbTX‐induced constriction, measured as percentage of diameter after 15 mm KCl‐induced vasoconstriction of pressurized UAs from NP, P14 and P18 γ1−/− mice (grey symbols, n = 4–6). Symbols are mean ± SEM.
