KDR and Stroke: Regarding EPCs populations, we observed that CD34+ and CD34+/KDR+/CD45− cells increased after stroke compared to controls (p < 0.001 and p = 0.005, respectively) and were elevated during the follow-up (3–6 months) compared to controls (p < 0.001 and p = 0.028, respectively; Figures 3F,G) despite a decrease in CD34+/KDR+/CD45− cells compared to pre-IRT levels (p = 0.004; Figure 3G).
