Mitogenic stimulation of mouse lymphocytes results in two sequential intracellular
alkalinizations. The first shift of intracellular p H from 7.18 to 7.35 coincides with early
biochemical events following mitogenic stimulation. The second alkalinization begins 12
hours after stimulation and rises in parallel with the rate of thymidine incorporation. The
results suggest that intracellular alkalinization following stimulation may play a key role in
the enhancement of cellular activation and mitogenesis.
