| Abstract: | The generation time of cells in the basal layer of the squamous epithelium of the forestomach was 55 hr. No cells were detected in the Go phase. The cells which had to become differentiated were located in the basal layer during 41 hr after division (maturing phase), and then migrated to the spinous layer. The basal layer consisted of two subpopulations: cells in the mitotic cycle (57 per cent of the basal cells) and maturing cells (43 per cent of the basal cells). The duration of the cell's life in the differentiated state was determined. It is emphasized that the ascertainment of the time of the maturing phase is important for a correct analysis of the dynamics of renewing cell populations. |
