摘要
Human endothelial cells derived from umbilical vein could besubcultured and survive 25 passage (double time 20～25 hours, 60～75 cumula-tive population doublings). An observation was performed with light mi-croscopy, electron microscopy and immunofluorescence microscopy using specificantiserum against factor Ⅷrelated antigen. It identified that the cultured cellswere endothelial cells. Medium RPMI-1640 supplemented with 20% humanserum, endothelial cell growth factor 200μg/ml, heparin 100μg/ml and gelatincoated flasks were very important conditions for long-term culture of humanendothelial cell.
