First U.S. Patients Treated With CRISPR As Human Gene-Editing Trials Get Underway
The powerful gene-editing technique called CRISPR has been in the news a lot. And not all the news has been good: A Chinese scientist stunned the world last year when he announced he had used CRISPR to create genetically modified babies.
But scientists have long hoped CRISPR â€” a technology that allows scientists to make very precise modifications to DNA â€” could eventually help cure many diseases. And now scientists are taking tangible first steps to make that dream a reality.
For example, NPR has learned that a U.S. CRISPR study that had been approved for cancer at the University of Pennsylvania in Philadelphia has finally started. A university spokesman on Monday confirmed for the first time that two patients had been treated using CRISPR....
