Scientists have said that using hearts from genetically modified pigs to help patients waiting for transplants is a possibility in near future.
In controversial research at the United States national medical research agency NIH, a research group led by Dr Muhammad Mohiuddin transplanted the hearts of genetically engineered pigs into baboons' abdomens and kept one beating for 600 days, Sky News reported.
Professor Chris Mason from University College London said that it is just a matter of 15 or more years now to achieve the ultimate breakthrough in the study.
