Californian scientists test a unique artificial kidney

The prototype organ can mimic haemodialysis.

Scientists at the University of California, San Francisco, recently tested a prototype of an artificial kidney completely identical to a real kidney. After an organ transplant, patients no longer have to depend on medication to artificially suppress the immune system or thin their blood.

The kidney contains a hemofilter to purify the blood as well as a bioreactor that controls metabolism. Furthermore, the organ dutifully regulates water volume, protects cells from immune system attacks, and performs other vital tasks.

Currently, the scientists are preparing for in-depth preclinical trials. After completing them, they intend to test the artificial organ in humans.
