Mitochondrial Transplantation Boosts Cardiac Arrest Recovery in Rats

Researchers at the Feinstein Institutes for Medical Research have achieved a 91% survival rate in rats after cardiac arrest by transplanting mitochondria into the ischemic brains of rats. Mitochondria, which produce energy through aerobic respiration, can no longer produce energy when blood flow and oxygen delivery stop. The study demonstrates the potential for mitochondrial transplantation in tissue protection and recovery, with improvements in rapid recovery of arterial lactate, glucose levels, cerebral microcirculation, neurological function, and decreased lung injury.
