ABSTRACT

Objective:

To determine the molecular weight and p urity of porcine platelet-derived growth factor (pPDGF) and to investigate its effect on DNA synthesis of human umbilical vein endothelial cells. Metho ds In the present experiment, the high performance liquid chromatograph y was used and the molecular weight and purity of pPDGF were studied. Human umbi lical vein endothelial cells was cultured and effects of pPDGF on DNA synthesis of endothelial cells was observed by 3H-TdR incorporation in vitro.

Results:

The findings of high performance liquid chromatography showed that the molecular weight of pPDGF was 29 120 and the purity was 89.46%, a nd pPDGF significantly promoted DNA synthesis of quiescent endothelial cells wit h a maximal response at a concentration of 40 ng/ml at 48 h.

Conclusion:

The molecular weight of pPDGF is 29 120, and it can promote DNA synthes is of cultured human umbilical vein endothelial cells.
