Nine-year-old Hassan can now enjoy a normal life after undergoing a first-of-its-kind surgery to replace most of the skin on his body. He has epidermolysis bullosa, a rare genetic skin disease that causes blisters and skin erosion.

By age 7, most of Hassan's body was raw with blisters, and he had lost most of his skin. This graphic shows how researchers decided on experimental gene therapy to treat his skin disease.

Using the boy's stem cells and transferring a healthy version of the gene that is normally defective in epidermolysis bullosa patients, the researchers were able to "grow" sheets of skin that could be transplanted onto his body.

The entire procedure involved doctors, researchers, pediatricians and plastic surgeons at hospitals and research facilities in Germany and Italy. The skin was prepared in Italy and transplanted in Germany.

Here is the grown skin: fibrin-cultured epidermal sheets. Fibrin substrate is used for burn victims.

Now, Hassan can go to school and play sports like a regular kid. He receives routine followups at the hospital to make sure that the treatment he received two years ago remains stable.
