From the article: “A key part of the team’s experiments was to transplant healthy mitochondria from skeletal muscle cells into cardiomyocytes of a different breed (nonautologous) to focus on questions specifically related to cell bioenergetics. The studies confirmed that cellular bioenergetics improves in the host cells two days after transplantation, but this supercharged state diminishes later on… This study showed for the first time, that it is possible to control cell bioenergetics by changing the content of the mitochondria in a cardiomyocyte,”
