Izpisua Belmonte and colleagues published work in the journal Nature last year reporting that they had been able to integrate human stem cells into early - stage mouse embryos so that the human stem cells began the first stages of differentiation — they appeared to begin the process of generating precursors of the body's various tissues and organs.
