Small sheets of healthy skin are being grown from scratch at a Stanford University lab, proof that gene therapy can help heal a rare disease that causes great human suffering.

The precious skin represents growing hope for patients who suffer from the incurable blistering disease epidermolysis bullosa and acceleration of the once-beleaguered field of gene therapy, which strives to cure disease by inserting missing genes into sick cells.

It is pink and healthy. Its tougher. It doesnt blister, said patient and research volunteer Monique Roeder, 33, of Cedar City, Utah, who has received grafts of corrected skin cells, each about the size of an iPhone 5, to cover wounds on her arms.

More than 10,000 human diseases are caused by a single gene defect, and epidermolysis bullosa is among the most devastating. Patients lack a critical protein that binds the layers of skin together. Without this protein, the skin tears apart, causing severe pain, infection, disfigurement and in many cases, early death from an aggressive form of skin cancer.

The corrected skin is part of a pipeline of potential gene therapies at Stanfords new Center for Definitive and Curative Medicine, announced last week.

The center, a new joint initiative of Stanford Healthcare, Stanford Childrens Health and the Stanford School of Medicine, is designed to accelerate cellular therapies at the universitys state-of-the-art manufacturing facility on Palo Altos California Avenue. Simultaneously, it is aiming to bring cures to patients faster than before and boost the financial value of Stanfords discoveries before theyre licensed out to biotech companies.

With trials such as these, we are entering a new era in medicine, said Dr. Lloyd B. Minor, dean of the Stanford University School of Medicine.

Gene therapy was dealt a major setback in 1999 when Jesse Gelsinger, an Arizona teenager with a genetic liver disease, had a fatal reaction to the virus that scientists had used to insert a corrective gene.

But current trials are safer, more precise and build on better basic understanding. Stanford is also using gene therapy to target other diseases, such as sickle cell anemia and beta thalassemia, a blood disorder that reduces the production of hemoglobin.

There are several diseases that are miserable and worthy of gene therapy approaches, said associate professor of dermatology Dr. Jean Tang, who co-led the trial with Dr. Peter Marinkovich. But epidermolysis bullosa, she said, is one of the worst of the worst.

It took nearly 20 years for Stanford researchers to bring this gene therapy to Roeder and her fellow patients.

It is very satisfying to be able to finally give patients something that can help them, said Marinkovich. In some cases, wounds that had not healed for five years were successfully healed with the gene therapy.
