  • Engineering the perfect baby

    MIT Technology Review - 03/05/2015

    Tilly predicted that the whole end-to-end technology—cells to stem cells, stem cells to sperm or egg and then to offspring—would end up being worked out first in animals, such as cattle, either by his lab or by companies such as eGenesis, the spin-off from the Church lab working on livestock. But he isn’t sure what the next step should be with edited human eggs. You wouldn’t “willy nilly” want to fertilize one, he said. You’d be making a potential human being. And doing that would raise questions he’s not sure he can answer. He told me, “‘Can you do it?’ is one thing. If you can, then the most important questions come up. ‘Would you do it? Why would you want to do it? What is the purpose?’ As scientists we want to know if it’s feasible, but then we get into the bigger questions, and it’s not a science question, it’s a society question.”
