...recent years, the curative promises of embryonic stem cells and therapeutic cloning methods have outshone other research, but these techniques are still too new and unproven to yield safe and effective treatments for patients. Atala's strategy has been to use already existing cells to create more practical solutions - for replacing everything from diseased heart muscle to worn out cartilage and failing kidney cells. "Every cell in your body is programmed to do a job, and our job is to put these cells in the right environment in the lab so they know what to do," he says...
...most remarkable feats of modern science - pulsing blood vessels, beating heart valves, and delicate, swollen human bladders. For nearly two decades, Atala has been perfecting the science of regenerating human tissues - essentially, the science of building new body parts. "The concept is to use the body's own cells to make new tissues and organs for patients who need them," he says. "We have had so many advances in various fields of science - cell biology, materials science, and stem cell biology - and all of them are coming together now to allow us to go one step further in the field...
...most cases, that cell comes right from whatever organ is ailing, and, in the ultimate feat of personalized medicine, from the ailing organ of the patient himself. Furthest along in development are regenerated human bladders, which are already being tested in early human trials and which Atala has thoughtfully designed in small, medium and large sizes. Not far behind on the organ assembly line are heart valves and blood vessels. Atala began with the bladder not only because of his training as a pediatric urologist, but also because bladder cells are among the many that can be grown outside...

...their mission also depends on improving security and development in their zone. They've seen how fragile their hold is on the region and know what idleness breeds. A car bomb thought to be made there killed 40 people in Fallujah during a funeral procession in May, and a cell of bomb makers was cut down by Iraqi police in Sinaa as recently as August. They say they are in a race against time. "Al-Qaeda is very weak, but all of Fallujah is still afraid," said Al Fallujy, the Sinaa mukhtar. "We've got an opportunity here," said Chief...
