A normothermic machine perfusion method for a pancreas is provided. First, a perfusate contained in a venous reservoir may be oxygenated such that a ratio of oxygen to carbon dioxide in the oxygenated perfusate is approximately 90%/10%. A first portion of the oxygenated perfusate may be pumped from the venous reservoir, through a dialysis filter, and back to the venous reservoir. A dialysate comprising a salt and glucose may be infused into the first portion of the oxygenated perfusate as the first portion is pumped through the dialysis filter. A concentration of glucose in the dialysate may be less than 8 mmol/L. A second portion of the oxygenated perfusate may be pumped through an arterial filter and through a pancreas graft. Venous outflow from the pancreas graft may then be pumped to the venous reservoir.

Methods are provided for preparing and treating graft tissue, such as a solid organ, for example a lung, comprising contacting the graft tissue with protective amounts of a heparanase inhibitor prior to and/or after transplantation of the graft tissue. Graft tissue, such as lung tissue prepared by the method also are provided. Methods are provided for transplanting graft tissue, such as a solid organ, for example a lung, comprising contacting the graft tissue with protective amounts of a heparanase inhibitor prior to and/or after transplantation of the graft tissue.

A system for the hypothermic transport of biological samples, such as tissues, organs, or body fluids. The system includes a self-purging preservation apparatus to suspend a sample in preservation fluid and perfuse a tissue with preservation fluid. The self-purging preservation apparatus is placed in an insulated transport container having a cooling medium. When assembled, the system allows for transport of biological samples for extended periods of time at a stable temperature.

A method of preserving a donor organ for transplantation may include flushing the donor organ with flush solution comprising itaconate and storing the flushed donor organ. The flush solution may comprise dimethyl itaconate (DI) in an amount greater than or equal to 0.1 mM and less than or equal to 0.75 mM. Following removal from storage, the donor organ may be perfused using an ex vivo organ perfusion (EVOP) process. The perfusate may also include itaconate.
