    • A cell delivery system for cell therapy comprising embryonic stem cells-derived cells is provided to prevent cancer or tumor which can be generated by directly transplanting the embryonic stem cells-derived cells in the body and to treat diseases. A cell delivery system for treating vasculitis insufficiency-related diseases comprising blood vessel endothelial cell specialized from embryonic stem cells is formed by inserting the specialized blood vessel endothelial cell to the inside of a cell carrier made of matrigel. The cell carrier is transplanted to the other site within an organism which directly does not contact a disease part. When the cell carrier is transplanted to the organism, the in vivo migration of the blood vessel endothelial cell specialized from the transplanted site is supressed by a carrier and is finally removed from the transplanted site.
