German researchers to breed pigs for human heart transplants

Plan based on simpler version of US-engineered animal used last month in world's first pig-to-human transplant

German scientists plan to clone and then breed this year genetically modified pigs to serve as heart donors for humans, based on a simpler version of a US-engineered animal used last month in the world's first pig-to-human transplant.

Eckhard Wolf, a scientist at Ludwig-Maximilians University (LMU) in Munich, said his team aimed to have the new species, modified from the Auckland Island breed, ready for transplant trials by 2025.
