This is a beginning though we need to use Chimpanzees. There is really good reason to conjecture that humanity is already a Boar Chimp Chimera that then successfully bred back to preserve the additional DNA.
So obviously such a hybrid can be used to produce usable organs. What ever you think of the overall ethical model, until we can produce organs directly, these strategies must be explored.
The science generated will also be important..
- Chimera piglets contained DNA from both pigs and cynomolgus monkeys
- They died within a week of being born at a laboratory in Beijing, China
- Scientists claimed the research aimed to find a way of growing human organs
