Artificial Kidney to Liberate Patients from Dialysis

An artificial kidney, also known as a bioartificial kidney or a kidney assist device, is a medical device or technology designed to replicate some or all of the essential functions of a natural human kidney. The primary function of the kidneys is to filter waste products and excess fluids from the blood, maintaining the body’s overall balance of electrolytes and fluids.

Artificial kidneys aim to provide a solution for individuals with kidney failure, particularly those on dialysis or awaiting kidney transplants. These devices typically involve a combination of filtration and cellular components to mimic the functions of a real kidney. There are various approaches to developing artificial kidneys, including implantable devices, wearable devices, and bioengineered tissues, each with the goal of improving the quality of life and health outcomes for individuals with kidney disease. Researchers and scientists continue to work on advancements in this field to offer more effective and accessible treatments for kidney failure.

Artificial Kidney Significant Findings

Researchers at the University of California San Francisco are developing a novel approach to treat kidney failure. This approach has the potential to liberate individuals from the necessity of dialysis or the use of immune-suppressing drugs post-transplant.

In a groundbreaking experiment, they demonstrated that kidney cells, enclosed within an implantable device known as a bioreactor, can thrive within a pig’s body and replicate several vital kidney functions. Remarkably, this device operates inconspicuously, akin to a pacemaker, without provoking the recipient’s immune system into defensive mode.

These significant findings, which were unveiled in a study published in Nature Communications on August 29, 2023, mark a notable advancement for The Kidney Project. The initiative is jointly led by UCSF’s Shuvo Roy, Ph.D. (technical director), and Vanderbilt University Medical Center’s William H. Fissell, M.D. (medical director).

In the future, scientists have plans to populate the bioreactor with various kidney cells responsible for crucial functions such as maintaining the body’s fluid balance and releasing hormones to regulate blood pressure. They will then combine it with a device designed to filter waste from the blood.

Moving forward with The Kidney Project, the team closely monitored both the kidney cells and the animals that received them for a duration of seven days after the transplantation. Encouragingly, both the cells and the animals showed positive outcomes. The next phase involves conducting trials lasting for a month, as mandated by the U.S. Food and Drug Administration (FDA), initially in animals and eventually in humans.

“We needed to demonstrate that a fully functional bioreactor can function without the need for immunosuppressive drugs, and we successfully achieved that,” explained Roy. “We encountered no complications, and we are now ready to progress further, aiming to replicate the entire range of kidney functions on a human scale.”
