(A) Histogram of vessel density computed by vascular segment diameter expressed as a percentage of total vessels in the outer cortex, (B) middle cortex, (C) and inner cortex. Values (mean ± SEM) that differ significantly from those of the uni-nephrectomized kidney group are represented by **p < 0.01.
