Sub-zero non-freezing of vascularized composite allografts in a rodent partial hindlimb model. Cryobiology 2024; 116:104950. [PMID: 39134131 PMCID: PMC11404353 DOI: 10.1016/j.cryobiol.2024.104950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 07/09/2024] [Accepted: 08/08/2024] [Indexed: 08/21/2024]
Abstract
Ischemia is a major limiting factor in Vascularized Composite Allotransplantation (VCA) as irreversible muscular injury can occur after as early as 4-6 h of static cold storage (SCS). Organ preservation technologies have led to the development of storage protocols extending rat liver ex vivo preservation up to 4 days. Development of such a protocol for VCAs has the added challenge of inherent ice nucleating factors of the graft, therefore, this study focused on developing a robust protocol for VCA supercooling. Rodent partial hindlimbs underwent subnormothermic machine perfusion (SNMP) with several loading solutions, followed by a storage solution with cryoprotective agents (CPA) developed for VCAs. Storage occurred in suspended animation for 24h and VCAs were recovered using SNMP with modified Steen. This study shows a robust VCA supercooling preservation protocol in a rodent model. Further optimization is expected to allow for its application in a transplantation model, which would be a breakthrough in the field of VCA preservation.

Prolonged Cold Ischemia Time in Mouse Heart Transplantation Using Supercooling Preservation. Transplantation 2020; 104:1879-1889.

Abstract
BACKGROUND Supercooling preservation techniques store a donor organ below 0°C without freezing. This has great advantages in inhibiting metabolism and preserving the organ in comparison to conventional preservation at 4°C. We developed a novel supercooling technique using a liquid cooling apparatus and novel preservation and perfusion solutions. The purpose of this study was to evaluate the preservation effect of our supercooling preservation technique in a mouse heart transplantation model. METHODS Syngeneic heterotopic heart transplantation was performed in 3 groups of mice: (1) the nonpreservation group, in which the cardiac grafts were transplanted immediately after retrieval; (2) the conventional University of Wisconsin (UW) group, in which the cardiac grafts were stored in UW solution at 4°C for different periods of time; and (3) the supercooling group, in which the cardiac grafts were stored in a novel supercooling preservation solution at -8°C for different periods of time. The maximal preservation time was investigated. Twenty-four-hour sample data were collected and analyzed to compare supercooling preservation to conventional UW preservation. RESULTS Our technique yielded a stable -8°C supercooling state. Cardiac graft revival was successfully achieved after supercooling preservation for 144 hours, and long-term survival was observed after supercooling preservation for 96 hours. Posttransplant outcomes, including myocardial ischemia-reperfusion injury, oxidative stress-related damage, and myocardial cell apoptosis, were improved in comparison to conventional 4°C UW preservation. CONCLUSIONS Supercooling heart preservation at -8°C greatly prolonged the preservation time and improved the posttransplant outcomes in comparison to conventional 4°C UW preservation. Supercooling preservation is a promising technique for organ preservation.
