Oscillating dissipative structures in mitochondrial suspensions.

The occurrence of spatial structures in the unstirred layer of an oscillating mitochondrial suspension is reported. The structures are detected by photo camera by light scattering in the unstirred layer of suspension. The spatial structures observed are shown to oscillate with the same period as that of mitochondrial oscillations in the bulk phase. Patterning is not affected by the layer depth within the range 0.3-3.0 mm. Various types of oscillatory states of mitochondria are characterized by the corresponding patterns. Patterning is effectively suppressed by the inhibitors of the respiratory chain (antimycin A or CN-).
