Figure 7 Early EPCs and Not OECs Augment Angiogenesis in a Paracrine Fashion

(A) A transwell apparatus was used to assess the paracrine effects of different EPCs. (B) Early EPCs, still exerted a dose-dependent proangiogenic effect when placed in transwells (TW) (p = 0.01 by analysis of variance). (C) The OECs did not exert proangiogenic effects when placed in transwells (p = 0.3 by analysis of variance). Data expressed as the mean ± SEM. *p < 0.05 versus control. CTRL = control; other abbreviations as in Figure 3.
