When the first baby born using a controversial procedure that meant he had three genetic parents was born back in 2016, it made headlines. The baby boy inherited most of his DNA from his mother and father, but he also had a tiny amount from a third person.
The idea was to avoid having the baby inherit a fatal illness. His mother carried genes for a disease in her mitochondria. Swapping these with genes from a donor—a third genetic parent—could prevent the baby from developing it. The strategy seemed to work. Now clinics in other countries, including the UK, Greece, and Ukraine, are offering the same treatment. It was made legal in Australia last year.
Complex gene therapies are starting to hit the market but all have faced the same reality: a tepid reception from the healthcare system and a cloudy path to profitability.
With their primary goal to advance scientific knowledge, most scientists are not trained or incentivized to think through the societal implications of the technologies they are developing. Even in genomic medicine, which is geared toward benefiting future patients, time and...
Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ring of cells.
