ESCs have the characteristic properties
of a stem cell: self-renewal and differentiation. These parent stem
cells, ESCs, give rise to progenitor cells, which are intermediate stem
cells that lose potency. Progenitor stem cells are committed to
differentiating along a particular cell developmental pathway.
ESCs will eventually produce endothelial cells (ECs), which create the
thin-walled endothelium that lines the inner surface of blood vessels
and lymphatic vessels.
