Background: It has been suggested that the initial differentiation of endothelial and hematopoietic cells during embryogenesis occurs from a common progenitor, called hemangioblast (hB). We hypothesized that these cells with dual hematopoietic/endothelial potential could be used in future regenerative medicine.
Methods: We used the two-step differentiation technology to generate bipotential blast cells from human embryonic stem cells (hES).
