<s>[INST] What is the status of the bioartificial kidney? [/INST] The implantable bioartificial kidney is under development, and we have not begun clinical trials. We have shown that the main functional components of the device (the hemofilter and the bioreactor) work together as intended in animals using small-scale prototypes. This gives us confidence that it will work in humans once the device is scaled up with enough capacity. Source: UC San Francisco. Link: https://pharm.ucsf.edu/kidney/device/faq. Field: Nephrology.
