People die waiting for replacement hearts, lungs and kidneys. Could genetically modified pigs be the solution to a worldwide shortage of organ donors?

We meet the teams that have had impressive recent successes transplanting pig organs into people. We鈥檒l explore the huge leaps of genetic engineering that are making 'xenotransplantation' possible and ask if it鈥檚 even ethical to try.

In the studio with Marnie Chesterton, Dr Graham Easton guides us through the science of getting pig organs to work in human bodies.

We also hear from transplant surgeon Dr Devagourou Velayoudam and Professor Nadey Hakim, on how these breakthroughs might benefit India and Nigeria, and other countries which don鈥檛 have the same medical and research resources of the US.
