Spheroids of differentiating embryonic stem cells, denoted embryoid bodies, constitute a high-quality model for vascular development, particularly well suited for loss-of-function analysis of genes required for early embryogenesis. This review examines vasculogenesis and angiogenesis in murine embryoid bodies and discusses the promise of stem cellbased models for the study of human vascular development.
Abbreviations used in this paper: 2D, two-dimensional; 3D, three-dimensional; EB, embryoid body; EC, endothelial cell; ESC, embryonic stem cell; HS, heparan sulfate; NDST, N-deacetylase N-sulfotransferase; VEGFR, VEGF receptor.
