Effects of puerarin on number and activity of endothelial progenitor cells from peripheral blood.
OBJECTIVE
To investigate whether puerarin can augment endothelial progenitor cells (EPCs) numbers, promote EPC proliferative, migratory, adhesive, and in vitro vasculogenesis capacity.


METHODS
EPCs were characterized as adherent cells by double staining of DiLDL-uptake and lectin binding under a laser scanning confocal microscope. Expression of KDR, VEGFR-2, and AC133 was detected by flow cytometry. EPCs proliferation, migration and in vitro vasculogenesis were determined with MTT assay, modified Boyden chamber assay, and in vitro vasculogenesis kit, respectively. EPCs adhesive assay was performed by replating those on fibronectin-coated dishes, then adherent cells were counted.


RESULTS
Incubation of isolated human MNCs with puerarin 0.1-3 mmol/L increased the number of EPCs, EPC proliferative, migratory, adhesive, and in vitro vasculogenesis capacity in a concentration- and time-dependent manner, which reached maximum at 3 mmol/L, 24 h (approximately 1-fold increase, P<0.01).


CONCLUSIONS
Puerarin enhanced EPCs functional activity.
