Abstract:
This study was aimed to look for the potential application of human umbilical plasma (HUP) in the culture of human umbilical vein endothelial cells (HUVECs). The effect of HUP concentration in cell culture medium on cell proliferation activity and cell cycle was studied. HUVECs were obtained by digesting the umbilical cord with 0.25% trypsin mixed with the equal volume of 0.1% collagenase II, then were identified by morphology and factor VIII immunohistochemistry under phase contrast microscopy. The cells cultured after 7 days showed the typical cobblestone morphology with factor VIII immunohistochemical staining positive. The study showed that the groups of 20% (HUP), 15% HUP+20% Fetal Bovine Serum (FBS) and 20% HUP+20%FBS enhanced cell proliferation activity significantly when compared with the control group (20% FBS without HUP). On the contrary, 30% HUP+20% FBS caused cell cycle arrest, which significantly hindered the proliferation of HUVECs. The study proved that although HUP might not be able to completely replace the role of vascular endothelial growth factor in cell culture, as a supplement ingredient, it was an ideal candidate to replace FBS in culture medium.
