Giel Hendriks discovered that the linking of sugars to the protein aquaporin-2 (AQP2) is necessary for the transport of water channels to the cell surfaces in the kidneys. If the protein is not linked to a sugar, it still forms functional water channels. However, these channels no longer end up at the cell surface where they need to do their work.
Kidneys extract water containing dissolved waste substances from the blood. Each day human kidneys produced about 180 litres of this so-called pro-urine. The excretion of all of this fluid would rapidly result in dehydration and eventual death. Therefore with the help of the water channels, the body returns about 99% of this water from the pro-urine to the kidney tissue. As a result of this a person only loses about 1.5 litres of urine per day.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
