The аpоptоtic index fоr а group of dividing cells is cаlculated as follows: Figure 1 shows the AI for a culture of fibroblast cells as a function of the surrounding concentration in parts per million (ppm) of a cell toxin. One thousand actively dividing fibroblast cells in culture were studied. Figure 2 shows the distribution of the cells in each of the stages of the dividing cell cycle. Electron micrographs were taken of the fibroblasts in culture. Figure 3 shows an example of cells in each of the 4 stages of the dividing cell cycle. Although the cells are not arranged in the sequence of the cell cycle, each stage is shown only once.
