In this study, we intravenously administrated the young mitochondria into aged mice to evaluate whether energy production increase in aged tissues or age-related behaviors improved after the mitochondrial transplantation. The results showed that heterozygous mitochondrial DNA of both aged and young mouse coexisted in tissues of aged mice after mitochondrial administration, and meanwhile, ATP content in tissues increased while reactive oxygen species (ROS) level reduced. Besides, the mitotherapy significantly improved cognitive and motor performance of aged mice. Our study, at the first report in aged animals, not only provides a useful approach to study mitochondrial function associated with aging, but also a new insight into anti-aging through mitotherapy. Use of a Handheld Skin Printer Improves Regeneration of Burn Injuries https://www.fightaging.org/archives/2020/03/use-of-a-handheld-skin-printer-improves-regeneration-of-burn-injuries/ Miniaturizing bioprinters to allow finely controlled printing directly onto (or into) the body is an important logistical advance in this part of the tissue engineering field. It allows for a much more efficient approach to building up new tissue where needed, such as injured skin. Researchers here demonstrate that their implementation of a handheld skin printer accelerates regeneration of severe burn injuries in animal models, suggesting they are a fair way along the road to having something that can be converted into a ...
