| Abstract: | The cell proliferation kinetics of the EMT6/M/AC tumour were determined at two volumes, 6-3 mm3 and 180 mm3, in mice treated with anti-mouse lymphocyte serum, AMLS. Comparison of the growth curve with that obtained in non-AMLS treated animals showed a marked increase in the growth rate at all volumes in the treated group. In contrast, the cell cycle time and the intermitotic phase times were not significantly different in the treated and untreated groups at comparable volumes. The increase in the growth rate in AMLS treated mice was obtained in spite of decreases in both the rate constant for cell production and the growth fraction, and was due to a marked decrease in the rate constant for cell loss. |
