Being under the cloud of needing regular dialysis is a pretty miserable cross to bear. I have a couple of friends and relatives who undergo this, so I have seen it "up close" to some degree. The kidney is the organ that essentially purifies the blood, removing or processing substances that would otherwise rather quickly allow us to die.
Thanks to the efforts of Vanderbilt University Medical Center nephrologist and Associate Professor of Medicine Dr. William H. Fissell IV, we are now looking a combination of living cells and nanotechnology than promise to be small enough to reside in the body and do the work of a failing kidney.
Fissell and his team use live kidney cells that will grow on and around the microchip filters. The goal is for these cells to mimic the natural actions of the kidney.
