Mitochondria constantly undergo fission and fusion events. These dynamical processes regulate mitochondrial morphology and are essential for cell physiology. We propose an elastocapillary mechanical instability as a mechanism for mitochondrial fission. We induce mitochondrial fission by rupturing the cell’s plasma membrane with a micropipette. We present a stability analysis that successfully explains the observed fission wavelength and the role of mitochondrial morphology in the occurrence of fission events.
