Design and Implementation of a Universal Donor Kidney

Area of Science:

• Biotechnology
• Biomaterials Science
• Nephrology

Background:

• Growing demand for donor kidneys exceeds supply, despite advances in kidney disease treatment.
• Current solutions like stem cell and xenograft technologies face significant scientific hurdles.
• There is a critical need for innovative kidney replacement therapies.

Purpose of the Study:

• To present the design rationale and technological choices for a novel BioArtificial Kidney (BAK).
• To detail progress towards creating an implantable BAK (iBAK).
• To address the organ donor shortage by developing an artificial kidney solution.

Main Methods:

• Development of a hybrid device integrating silicon nanopore membranes with living kidney cells.
• Utilizing cellular components for blood filtration and waste concentration.
• Engineering a system for potential implantation.

Main Results:

• A functional hybrid device capable of filtering blood and concentrating waste into urine has been developed.
• Key design and technology choices have been established.
• Significant progress has been made towards the goal of an implantable BioArtificial Kidney.

Conclusions:

• The developed hybrid device shows promise as a component of an implantable BioArtificial Kidney.
• This approach offers a potential solution to the persistent shortage of donor kidneys.
• Further development is ongoing towards a fully functional iBAK.
