title: [Number of nucleoli as an index of the proliferative activity of cells in vitro].
abstract: The number of nucleoli in cells is commonly insignificant (from 1 to 2). It may increase under numerous normal (regeneration) and pathological conditions. The data obtained suggest that activation of the nucleoli and the increase in the number cannot be specific characteristics of any pathological condition. Any disorders of tissue proliferative homeostasis will result in a change in the ratio of proliferative and resting cells and increase in the number of nucleoli.
