Scientists have created the world’s first human-sheep chimera – which has the body of a sheep and half-human organs.
The sheep have 15 per cent human cells and 85 per cent animal cells –
and their evolution brings the prospect of animal organs being
transplanted into humans one step closer.
Professor Esmail Zanjani, of the University of Nevada, has
spent seven years and Â£5million perfecting the technique, which
involves injecting adult human cells into a sheep’s foetus.
