APLN and Stroke: The scanning imaging showed that stroke animals that received apelin-13 treatment had significantly greater recovery of local blood flow compared with the stroke control animals (77.2 ± 3.5% vs. 85.9 ± 0.27% in stroke + vehicle and stroke + apelin-13 groups, respectively; p < .05; n = 10 each group; Figure 5(a) and (b)).
