Scientists successfully used stem cell and gene therapy to replace 80% of the skin of a 7-year-old boy affected by an incurable genetic skin disease, they report Wednesday in Nature.

Why this matters: This is the first time researchers have been able to regenerate virtually the entire epidermis and also provides a blueprint for other stem cell and gene therapies. And, while the scientists cautioned more testing is needed to see if this could be used for the roughly 500,000 people worldwide with different forms of this particular disease, they said this experiment was a success.
