A HYBRID human-pig embryo has been injected into a sow’s womb as scientists push the ethical boundaries of science in the hope that they can create lifesaving donor organs.
Scientists from the Salk Institute – a biological research organisation in California – have taken cells from pigs and people to create an embryo that was then inserted into a female pig.
As part of initial experiments, several different types of human cells were inserted into pig embryos in petri dishes to determine which cells were the best match for the pig embryo.
The human cells which worked best with the pigs’ were infant ones which have the potential to develop into all adult cell types – known as a pluripotent cell.
