Kinetics of cell replication of the uterine cervix. II. Parabasal cell production in atypical epithelium.
The rate of cell division during a 6-hour period of time was determined in cervices from 31 mice, 16 having normal epithelium, 8 with atypical epithelium and 7 with invasive carcinoma. Cervical atypias and carcinoma were induced by local application of benzo(a)pyrene (BP) and mitosis was arrested with vincrotal number of cells in all layers as well as the proportion of dividing cells in the parabasal layer were significantly greater in atypias and invasin cell production in that layer.
