The cells were homogenized with 10 strokes of a Teflon homogenizer, and the homogenates were centrifuged twice at 750g for 10 min at 4°C. The supernatants were centrifuged at 10,000g for 15 min at 4°C, and the resulting mitochondria pellets were resuspended in buffer A containing 250 mM sucrose and frozen in multiple samples at -80°C. The supernatants of the 10,000g spin were further centrifuged at 100,000g for 1 hour at 4°C, and the resulting supernatants (designated S-100) were divided into samples and frozen at -80°C for further experiments.

On day 2, cells were treated either with staurosporine (added to a final concentration of 1 μM) for 0, 1, 2, 4, and 6 hours, or with etoposide (added to a final concentration of 50 μM) for 0, 2, 3, and 4 hours. The S-100 supernatants and mitochondria from these treated cells were prepared as described in (17).

    • neo and Bcl-2 cells were set up and treated with staurosporine as described in (17). After centrifugation at 600g for 10 min at 4°C, the cell pellets were resuspended in PBS containing 5 μM rhodamine 123 (Sigma) and incubated at 37°C for 15 min. The cell suspension was centrifuged in a microcentrifuge for 30 s, and the pellet was resuspended in 20 μl of PBS, plated onto a 25-mm round glass cover slip coated with poly-D-lysine, and mounted into a perfusion chamber for confocal imaging. The fluorescence images were collected with a Meridian Insight-Point Laser scanning confocal microscope (Meridian Instrument) equipped with a Zeiss Axioplan microscope. The objective lens was a 100x numerical aperture 1.4 PlanApo lens. The aperture size of the pinhole was 10 to 40 μm. Confocal optical sections were estimated to be less than 1 μm in thickness. Cells were excited with the 488-nm line of an argon laser, and emitted fluorescence was detected through a 530/30 band-pass filter with an intensified, cooled charge-coupled-device camera. A typical cell from a population of ̃ 100 was presented.
