The ability to grow the cells of one species within an organism of a different species offers scientists a powerful tool for research and medicine, yet developing such capabilities has been a formidable challenge. US and Chinese researchers, led by Professor Juan Carlos Izpisua Belmonte from the Salk Institute for Biological Sciences, have now come one step closer towards this goal by realising the integration of human cells into animal tissue.
