On April 4 , 2006 , it was announced that a team of biologists at the Wake Forest University School Of Medicine , led by Professor Anthony Atala , had created the world's first lab-grown organ, a bladder, and Transplanted it into a human. Seven people between the ages four and 19, received transplants. The bladders were grown from the patients' own Cellular Tissue , so there was no risk of Transplant Rejection . DEVELOPMENT On January 30 , 1999 , scientists announced that a lab-grown bladder had been successfully transplanted into dogs. These artificial bladders worked well for almost a year in the dogs. In 2000 , a new procedure for creating artificial bladders for humans was developed. This procedure is called an orthotopic neobladder procedure. This procedure involves shaping a part (usually 35 to 40 inches) of a patient's Small Intestine to form a new bladder. PROCEDURE First a CT Scan of the patient is taken, to determine the shape of the bladder that must be created. Next a tissue sample is taken from the patient's bladder. These cells are grown (this part of the process usually takes 4 weeks), and then layered onto a Biodegradable " Scaffold " in the shape that the required bladder is to take. Finally, the transplant procedure takes place. The entire bladder along with the biodegradable "scaffold" is transplanted. Over time, the biodegradable "scaffold" will degrade within the patient's body. EXTERNAL LINKS
