Dr. Juan Carlos Izpisua Belmonte, a developmental biologist at the Salk Institute for Biological Studies in La Jolla, California, and his colleagues have stumbled across a previously unknown variety of pluripotent stem cell. Named region-selective pluripotent stem cells (rsPSCs), these cells grow more quickly and stably than other pluripotent cells, and can grow in animal embryos. Additionally, these rsPSCs can be more easily edited at the gene level than other cells. This combination could lead to a method that allows scientists to create animals with human organs. Organs that could be used to better test drugs for safety and efficacy, and possibly even be used for transplants.
