Nevertheless, this study shows that this method of treatment—replacing part of an organ with genetically corrected stem cells grown in a lab—is feasible. Researchers are currently working on a phase one clinical trial to try it on other people with this specific condition, but future research will help determine if it can help patients with other life-threatening skin problems. If successful, De Luca said in a press conference, it could prove to be a better option than transplants from donors, which carry the risk that the new host's body will violently reject the foreign cells. Many organ recipients spend the rest of their lives on drugs that suppress the immune system—a dangerous price to pay for a new body part, no matter how badly it's needed. Edited stem cells offer the tantalizing alternative of an organ that is made from the patient's own body, but with dangerous imperfections removed. Here's to hoping that the treatment is ready for prime time soon.
