Human Mesenchymal Stem Cells Increase Anti-oxidant Defences in Cells Derived from Patients with Friedreich's Ataxia

Friedreich's ataxia (FRDA) is a progressive neurodegenerative disorder which is, at present, incurable. Oxidative damage and inhibition of mitochondrial function are key determinants of cellular damage in FRDA, since there is greater sensitivity to oxidative stress in cells with frataxin deficiency. In addition, frataxin-deficient cells have an impaired ability to recruit antioxidant defences against endogenous oxidative stress.
