Different permeability and recruitment ability of HDLECs compared to HUVECs. A. Diagram of permeability assays of endothelail cells. B. Higher permeability was found in HDLECs. C. Less expression of PDGF-BB in HDLECs compared to HUVECs. D. Diagram of recruitment ability of endothelial cells by measuring the migrated SMCs in co-culture system. E. More SMCs were migrated across the membrane in co-culture system with HUVECs. All data are presented as mean ± SE from three different experiments with duplicate. *, P < 0.05; **, P < 0.01 versus HUVECs.
