Fig. (2) Quantification of the number and the length of capillaries. The results, repeated three times, are expressed as the capillary length (Fig. 2A) and capillary number (Fig. 2B) as described in the Methods section. In Fig. (2A), compared to control all other columns show p<0.001; compared to eplerenone alone both aldosterone and aldosterone + eplerenone also show p<0.001. In Fig. (2B), compared to control, aldosterone alone, eplerenone alone or aldosterone + eplerenone = p<0.003; eplerenone vs aldosterone = p<0.003; eplerenone vs aldosterone + eplerenone = p<0.021.
