The degenerative phase was characterized by progressive cell loss, increased nuclear volume, and a lower mitotic index. The cell loss was complete or maximal by twenty-one days. The regenerative phase was characterized by discrete islands of proliferating cells, first seen at twenty-one days. These islands increased in diameter; by twenty-eight days they had fused into a re-epithelialized surface which then became hyperplastic. The apparent doubling time of the regenerating phase was 3.3 days.Article HistoryPublished in print: Apr 1972 FiguresReferencesRelatedDetailsCited ByChanges in epidermal radiosensitivity with time associated with increased colony numbersThe British Journal of Radiology, Vol. 74, No. 881Recommended Articles RSNA Education Exhibits RSNA Case Collection Vol. 103, No. 1 Metrics Altmetric Score PDF download
