Chimerism Research Hits Milestone with Hybrid Human-Pig Embryo

Professor Juan Carlos Izpisua Belmonte at La Jolla’s Salk Institute for Biological Studies, and his team of researchers, have successfully introduced pluripotent human stem cells into pig blastocysts that then developed into a viable embryo. The stem cells took up residence in the spaces that would indicate development of human-compatible organs including the heart, liver, and kidneys. Current regulations prevent the scientists from allowing the embryo to continue to develop, but this research offers promise in the quest to one day eliminate organ transplantation waiting lists.
