Scientists have created a human-pig hybrid in a milestone study that raises the prospect of being able to grow human organs inside animals for use in transplants. This is an important first step.”The study has reignited ethical concerns that have threatened to overshadow the field’s clinical promise. Scientists created the first rat-mouse chimeras a decade ago, but until now have struggled to combine human cells with those of a large mammal. 'Chimera' monkeys created in lab by combining several embryos into one Read moreSimilarly, the human cells could be engineered to prevent them contributing to the chimera brain. [This field of work] could provide a platform for human cells to do that.”
