Mitochondrial Fragmentation Prior to Cytokinesis.

<p>(A) Mitochondria were tracked through mitotic division events in U2OS_mitoEYFP cells by confocal microscopy. An example cell is shown representing a 3D reconstruction of a 6 μm z-stack (1 μm thick slices) that has been re-colored according to the depth (see color coded legend) of the fluorescent signal within the z-stack. Insets are 3.5x magnifications of boxed regions. (B) Example cells are shown which demonstrate similar morphological alterations in mitochondrial reticulum throughout multiple mitotic cell divisions.
