After decades of research, pigs could be considered as organ donors for human beings.
A team of Harvard scientists engineered pig tissue so that it could not be rejected by the human body using a technology known as Crispr where a bacterially derived protein to cut-away a particular gene is replaced or repaired by another molecule introduced at the same time.
George Church, a professor of Genetics at Harvard Medical School, says the study was driven by the need to create a steady supply of human organs for transplant by growing them in pigs.
