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.

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.
The cells that survived eventually formed a human/pig embryo, which were then injected into female pigs and allowed to develop for around a month.
