[The intracellular significance of pH, its dynamics and possible role in regulating cell functions].
The intracellular and intralysosomal pH were studied on living monolayer cell cultures SPEV (pig embryo kidney), CHC (Chinese hamster's fibroblasts), NGUK-1 (neurinoma of Gasser's gland of rat), and also on primary cell cultures of rat's hepatocytes and chick embryo fibroblasts. In cytoplasm and lysosomes of these cells were found out pH changes during cells cycle and cell cultivation. There was also showed a heterogeneity of different parts of cells and lysosomes, and circahoral pH oscillations were registered. So there was found a spatial and temporal pH mosaity of living cells. The probable role of intracellular pH changes via regulator of cell vital activity is discussed.
