[Culture of human blood vessel endothelial cells--a simple and inexpensive culture method].

The purpose of this review is to introduce a simple and inexpensive culture method for human umbilical blood vessel endothelial cells. The medium used is MCDB-104 supplemented with 10% fetal bovine serum, 70 ng/ml endothelial cell growth factor from new-born bovine brains, 10 ng/ml murine epidermal growth factor, and 100 micrograms/ml heparin. The culture dishes are coated with gelatin. Under these conditions, endothelial cells from human vessels were grown with doubling times of 18-22 hrs and reached saturation densities of 8-12 x 10(4) cells/cm2. To determine the lifespan of the endothelial cells, the cells were serially subcultivated weekly at an inoculum size of 1,000 cells/cm2. Human endothelial cells from umbilical vein and artery were grown for 21 to 37 passages with 55 to 125 population doublings. This culture method seems to be useful for studying cell proliferation and functions of human endothelial cells.
