Acute spinal cord injury is associated with mitochondrial dysfunction in mouse urothelium.

Aim: To characterize the effects of acute spinal cord injury (SCI) on mitochondrial morphology and function in bladder urothelium and to test the therapeutic efficacy of early treatment with the mitochondrially targeted antioxidant, MitoTempo.

Methods: We used a mouse model of acute SCI by spinal cord transection between the T8-T9 vertebrae with or without MitoTempo delivery at the time of injury followed by tissue processing at 3 days after SCI. Control, SCI, and SCI-MitoTempo-treated mice were compared in all experimental conditions.
