Perfluorocarbon for organ preservation before transplantation

Area of Science:

• Biomedical Engineering
• Organ Transplantation
• Biomaterials Science

Background:

• Perfluorocarbons (PFCs) are oxygen carriers with high oxygen solubility and effective release.
• PFCs have been explored for their potential in medical applications, including organ preservation.

Purpose of the Study:

• To evaluate the efficacy of the two-layer method (TLM) using PFCs for pancreas preservation.
• To assess the impact of TLM on organ viability, graft survival, and islet isolation.

Main Methods:

• The two-layer method (TLM) combines University of Wisconsin (UW) solution with PFCs and oxygen for organ preservation.
• Pancreata were preserved using TLM, allowing for oxygenation via PFC and substrate supply via UW solution.
• Canine models were used to assess the repair of warm ischemic injury and graft survival post-transplantation.

Main Results:

• TLM-preserved pancreata generated adenosine triphosphate during storage, prolonging preservation.
• TLM demonstrated repair and resuscitation of warm ischemic injury in canine pancreata.
• Improved pancreas graft survival and enhanced islet yields were observed after transplantation.

Conclusions:

• The TLM is a promising method for pancreas preservation, improving outcomes in transplantation and islet isolation.
• TLM shows benefits for preserving other challenging organs, including the heart and small bowel.
