GM pigs closing to being human organ donors


US researchers claim the most genetically modified animals in existence have been created to help end a shortage of organs for transplant. 

The scientists announced they have successfully rid 37 pigs of viruses hiding in their DNA, overcoming one of the major barriers to transplanting pig organs to people. 

The team at eGenesis however admits preventing pig organs from being rejected by the human body remains a huge challenge, but experts have said it is a promising and exciting first step.
