Extensive Fusion of Mitochondria in Spinal Cord Motor Neurons
Figure 3
Time course of the fusion of individual mitochondria.
A living neurite (28 div) with mitochondria containing photoconverted mitoKaede was imaged over several hours. The appearance of green fluorescing mitoKaede within individual red fluorescing mitochondria (labeled i- iii) during 4 hours of observation is seen. The arrow indicates the location of a mitochondrion that had entered the field of view before the first image was taken. By 20 hours, the red fluorescent protein was distributed throughout the mitochondria under observation. Scale bars correspond to 5 microns.
