Keeping donated livers usable longer using improved supercooling

Enhanced supercooling for extending non-freezing preservation in preclinical porcine and human donor livers

NIH-funded research Sylvatica Biotech, INC. · NIH-11193544

This project uses an improved supercooling method to keep donated livers viable for longer so more people who need liver transplants can get better-matched organs.

What this research studies

From a patient's perspective, the team is developing a way to cool donor livers below 0°C without forming damaging ice, a process called supercooling. They will test the method in the lab on porcine livers and on human donor livers using vascular flush and controlled cooling to maintain a non-freezing, metastable state. The researchers will monitor markers of liver viability and survival after different storage times to see how long function can be preserved. If the method is safe and reproducible, it could move toward clinical testing and allow livers to be stored for days instead of hours.

Who could benefit from this research

Good fit: People with end-stage liver disease who are listed for or being evaluated for liver transplantation would be the eventual beneficiaries and candidates for future clinical trials.

Not a fit: Patients who are not transplant candidates because of severe comorbidities, active infection, or other contraindications to transplant may not benefit from this work.

Why it matters

Potential benefit: This could increase the time donor livers stay usable from hours to days, allowing better matching, longer transport, and potentially fewer deaths on the waitlist.

How similar studies have performed: Preclinical studies, including prior work by this group, have shown promising results with supercooling to extend liver preservation for multiple days, but broader validation and translation to clinical use remain needed.
