Scientists have now genetically-altered pigs in the most number of ways to date, bringing us closer to the possibility of successful xenotransplantation -- the process of transplanting animal organs into humans.
The total number of modified genes in these pigs is 60, making their organs more like humans' so that the body's immune system is less likely to reject. While many would assume a member of the ape family may be more closely linked, a pig's organs are actually the most similar in size and system to a human's.
While a controversial issue, largely with vegans and vegetarians, this is a vital step forward for science. While alternative stem cell research has its own set of issues as well, both of these routes will be studied as more humans are put on wait lists for vital organs.
