Summary. The present review summarizes knowledge accumulated during the last decade concerning in vitro endothelial differentiation from embryonic stem (ES) cells. There is now growing evidence that ES cells may provide a powerful model system to determine the cellular and molecular mechanisms of vascular development. ES cells differentiate into the endothelial lineage by successive maturation steps recapitulating in vivo events observed in the embryo. Further maturation of ES-derived embryoid bodies either in three dimensional gels or in confrontation cultures with tumor spheroids can also provide a model of physiological or tumoral angiogenesis. The data obtained from experimental in vitro differentiation of genetically modified mouse ES cells highlight the potential and the complementarity of this model system to in vivo gene knock out studies. We also consider and discuss some of the potential applications of ES cell technology in vascular biology for future directions in basic research and medicine, by manipulation of differentiation and the generation of cell populations for analysis and transplantation for therapeutic use.
