A sizable fraction of cell signaling is carried in extracellular vesicles, membrane-wrapped packages of molecules. In the course of investigating cell signaling, researchers have noted that some fraction of these vesicles are in fact mitochondria. Cells can readily ingest mitochondria, just as they do other vesicles, and put the mitochondria to work. Mitochondria are organelles descended from ancient symbiotic bacteria, primarily responsible for generating chemical energy store molecules to power cell processes, but also deeply integrated into a wide range of cellular mechanisms beyond this. Mitochondria have their own DNA, replicate like bacteria, and are cleared when …
