investigation of the variations in the index of labeled mitoses throughout 90 hours after a single injection to mice of 3h-thymidine at 01 or at 13 o'clock ( the periods of the maximal and minimal labeling index in the circadian rhythm of cell proliferation ) showed that the cell population which had completed synchronously the mitotic cycle during the first day of experiment also plays the main role in the formation of the peak rhythms in the mitotic index in the following days .
