Effect of 8-pCPT-2′-O-Me-cAMP on the migration of EPC on matrix proteins. EPC migration assays on fibronectin (n = 19) (A) or fibrinogen (n = 11) (B) were performed. EPCs were stimulated in suspension with addition of PBS (control) or with 8-pCPT-2′-O-Me-cAMP 100μM. After washing out 8-pCPT-2′-O-Me-cAMP, EPCs were allowed to migrate. Data are presented as mean migrated cells (% of control) plus or minus SEM. * indicates Pless than .05 vs control.
