Should we play the Mother Nature game with genetics and life as we know it?
After a nearly year-long ban, on August 4 the NIH said it would soon lift its moratorium and again start accepting grant applications from research labs that want to develop human-animal chimeras. “We thought it was good time to take a deep breath, pause and make sure the ethical frameworks that we have in place allows us to move forward and conduct this research responsibly,” says Carrie Wolinetz, associate director for science policy at NIH.
But it could become an important tool for medical research. Scientists have mixed-and-matched human and animal cells for years, hoping to one day grow replacement human organs or discover genetic pathways of human diseases.
