Artificial organ a stationary power supply or other stationary resources such as filters or chemical processing units. (Periodic rapid recharging of batteries, refilling of chemicals, and/or cleaning/replacing of filters would exclude a device from being called an artificial organ.) Thus, a dialysis machine, while a very successful and critically important life support device that almost completely replaces the duties of a kidney, is not an artificial organ. Constructing and installing artificial organs, an extremely research-intensive and expensive process initially, may entail many years of ongoing maintenance services not needed by a natural organ.: The use of any artificial organ by humans is
Regeneration in humans spinal nerves. Researchers, from University of Edinburgh, have succeeded in regenerating a living organ. Regenerated organ is closely resembled with juvenile thymus in terms of architecture and gene expression profile. The thymus gland is one of the first organs to degenerate in normal healthy individuals. Between the years 2005 and 2008 four women with vaginal hypoplasia due to Müllerian agenesis were given regenerated vaginas. Up to eight years after the transplants all organs have normal function and structure. Regeneration in humans Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast
