Building an Implantable Artificial Kidney
Abstract:
A collaborative, multidisciplinary group of labs is working to create the first implantable artificial kidney. The prototype, revealed last week, is compact, no larger than a soup can. It not only filters toxins out of the bloodstream but also uses human kidney cells to perform other vital functions, such as regulating blood pressure and producing vitamin D.
"Dialysis is not only time-consuming, but it's also debilitating. Many patients don't feel good, because it's not doing all the functions of a normal, healthy kidney," says bioengineer Shuvo Roy, whose lab at the University of California, San Francisco produced the new device and is already testing it in animals. "The kidney doesn't just filter toxins. It also has metabolic functions and hormonal functions, and dialysis doesn't capture these abilities."
