Abstract
Mitochondrial transfer (MT) is a biological process that allows a donor cell to horizontally share its own mitochondria with a recipient cell. Mitochondria are highly dynamic membrane-bound sub-cellular organelles prominently involved in the regulation of the cell energy balance, calcium homeostasis, and apoptotic machinery activation. They physiologically undergo fusion and fission processes in response to the cell requirement, with a continuous morphological re-arrangement. This structural and functional plasticity is at the basis of the MT, described in tissue regeneration, cardiac and neurological diseases, as well as in cancer. Here, the MT has been observed in the tumor micro-environment (TME) from the adipose-derived stem cells (ASCs) to the cancer cells, eventually reverting the lack of the mitochondria respiration function, or enhancing their motility and drug resistance. In this chapter, we outline some key protocols for evaluating this exciting phenomenon of MT. These methodological and technical approaches are very important, considering all the limitations that scientists constantly face, especially in this field of the research.
