Abstract:Mitochondria are responsible for coordinating cellular energy production in the vast majority
of somatic cells, and every cell type in a specific state can have a distinct metabolic signature. The
metabolic requirements of cells from different tissues changes as they proliferate/differentiate, and cellular
metabolism must match these demands. Proliferating cells, namely cancer cells and stem cells,
tend to prefer glycolysis rather than a more oxidative metabolism. This preference has been exploited for the improvement
of new biotechnological and therapeutic applications. In this review, we describe mitochondrial dynamics and energy metabolism
modulation during nuclear reprogramming of somatic cells, which will be essential for the development and optimization
of new protocols for regenerative medicine, disease modeling and toxicological screens involving patientspecific
reprogrammed cells.
