First monkey human embryos reignite debate over hybrid animals
Scientists have successfully grown monkey embryos containing human cells for the first time the latest milestone in a rapidly advancing field that has drawn ethical questions.
In the work, published on 15 April in Cell1, the team injected monkey embryos with human stem cells and watched them develop. They observed human and monkey cells divide and grow together in a dish, with at least 3 embryos surviving to 19 days after fertilization. The overall message is that every embryo contained human cells that proliferate and differentiate to a different extent, says Juan Carlos Izpisua Belmonte, a developmental biologist at the Salk Institute for Biological Studies in La Jolla, California, and one of the researchers who led the work.
