Pigs to People

A pig

In his usual understated and modest way, the media-savvy scientist/entrepreneur Craig Venter planted a seed that grew into a thoroughly misleading headline in the San Jose Mercury News:

Synthetic biologist aims to create pig with human lungs

Not exactly. The pig would have pig lungs, but with some tweaks that would reduce at least the initial rejection of the organ by a human recipient’s immune system. Sounded good, though!

Previous reports indicated that Venter’s Synthetic Genomics is working on this project with Lung Biotechnology Inc, a subsidiary of United Therapeutics, which is run by the noted transhumanist Martine Rothblatt. This is what Venter was quoted as saying at SynBioBeta 2014:

“We are re-engineering the pig, changing its genetic code. If we succeed with rewriting the pig genome, we will have replacement organs for those who need them.”

That is not actually a novel idea. Lord Robert Winston, best known as a British fertility expert, explained the rationale to the London Telegraph in September 2008:

“Pigs’ organs are the right size for human transplantation, and they work similarly to human organs. Of course this raises a moral problem, but it is much more ethical to use a pig to save a human life than to use it for relatively unnecessary meat eating.”

Winston was frustrated by British and EU regulations (“bureaucracy” and undefined “red tape“), and moved his company Atazoa to Missouri to continue the work. He was confident in 2008 that “we can produce transplantable organs within two or three years … Within 10 years we think they could be available for hospitals.” The goal was “humanised hearts, lungs or livers” and the process would be to modify sperm and breed the pigs to order.
