Figure 9. Inhibition of α adrenoceptor and β 2 adrenoceptor attenuated the elevation of the proportion of EPCs in peripheral circulation.

Figure 9

Cells from peripheral blood were lysed and analyzed with flow cytometry. Cells were sequentially gated based on CD45 (A), CD34 and KDR expression (C). Circulating EPCs were defined as CD45-/CD34+/KDR+ cells. A gate was used to select the total CD45- cell population (A). Corresponding flow cytometric analysis was used to detect CD34+/KDR+ cells in the gated CD45- cell population. Co-treatment of either phentolamine or I127 with NE significantly attenuated the increases of EPCs in peripheral circulation, but Metoprolol didn't (B, *P<0.05 compared with the model group.). Representative flow cytometric analysis of EPCs (CD34/Flk-1 cells) were showed in part C.
