Human iCell® endothelial cells are now available for use in vascular-targeted drug discovery, tissue regeneration, and other life science research. iCell endothelial cells are derived from human induced pluripotent stem (iPS) cells, actively proliferate, are capable of arranging themselves into tubular formations, and exhibit biochemical properties of normal human endothelial cells. Because they are human cells, they may better recapitulate human biology and may be better predictors of drug candidate responses than current cell models. iCell endothelial cells are manufactured in industrial quantities with more than 95% purity.
