But what about the children who could live with jerry-rigged bladders for decades? This is a question Anthony Atala asked himself as a surgical resident training in pediatric urology. "These children had an 80-year life expectancy," he says. "They are going to have a lot of problems."

The ideal solution, Atala reasoned, was to provide children with new tissue from their bladders, not their intestines. This meant growing a vast amount of new, autologous bladder cells. In 1990, out of...
