Hypothermia (0deg to 4deg C) is a critical component of successful organ cold storage because:

Oxygen is more soluble in cold solutions and provides a continual supply for energy metabolism

There is no way to suppress microbial growth except by cooling and slowing the growth rate

Hypothermia diminishes energy requirements and allows the limited energy reserve to keep the organ alive

It slows metabolism and the enzymic processes that would destroy the cell
