Supercooling technique advances preservation of human tissue

“Researchers at UC Berkeley successfully revived human heart tissue after it had been preserved in a subfreezing, supercooled state for 1 to 3 days.  . . . The researchers submerged the heart-on-a-chip in a rigid chamber filled with a common organ preservation solution that had been chilled to minus 3 degrees Celsius. They removed the heart cells from the solution after durations of 24, 48 or 72 hours, and returned them to a warm 37 degrees Celsius.  Examination of the heart tissue confirmed that isochoric supercooling had not altered the structural integrity of the heart tissue, nor did it significantly affect the beat rate or beat waveform.” MORE
