Another major obstacle to clinical use of cultured endothelial cells is the potential of immune rejection when the cells are injected into a patient. To address this risk, one approach would be to create a large, genetically diverse bank of human embryonic stem cells that, on demand, could be converted into endothelial cells that are compatible with specific patients.
"Given the success rate our group has shown in generating human embryonic stem cells from donated normal and diseased embryos, this new approach has broad implications not only for regenerative medicine, but also for the study of genetic diseases of the vasculature," states Dr. Zev Rosenwaks, who is director and physician-in-chief of the Ronald O. Perelman and Claudia Cohen Center for Reproductive Medicine as well as the director of the Tri-Institutional Stem Cell Initiative Derivation Unit at Weill Cornell Medical College.
The new endothelial cell culture is currently being validated in ongoing research at Weill Cornell using a number of stem cell "lines," or "families" of stem cells. "Employing a highly sophisticated derivation technology, we have been able to generate 11 normal and diseased human embryonic cell lines from discarded embryos at the Tri-Institute Derivation Unit at Weill Cornell," states Dr. Nikica Zaninovic, an assistant professor at the Department of Reproductive of Medicine who is spearheading the human embryonic stem cell derivation effort. Using the new differentiation methods, several of these new embryonic stem cell lines have been turned into vascular cells.
Testing in humans is the next major step in verifying the ability of this breakthrough cell-based approach to restore blood supp
