Supplementary table 1.

Average body weight and the number of posterior communicating arteries (PcommAs) per animal in the wt and Nfkb1-ko male and female mice. Data are shown as mean ± SEM. P values are derived from Student’s t-test; *** p < 0.001 in comparison to the wt female animals.

Gender	Genotype	Body weight, g	PcommAs per animal
Male	Nfkb1-wt	34.5 ± 0.6	1.3 ± 0.2
	Nfkb1-ko	35.4 ± 0.7	1.4 ± 0.1
Female	Nfkb1-wt	26.1 ± 0.6	1.5 ± 0.1
	Nfkb1-ko	23.4 ± 0.3***	1.3 ± 0.2
