Confocal image (cLSM) of a living PC-12 cell. PC-12 cells are immortal rat (Rattus norvegicus) pheochromocytoma cells and undergo neuron like differentiation after treatment with nerve growth factor. Mitochondria are stained in red (Mitotracker red), the nucleus is seen in blue (DAPI). Microtubules are stained in green (Tubulintracker green). Mitochondria form dense networks in the cells soma and are transported along microtubules via motorproteins into the cells processes to accumulate in synapse like structures.
