Microcolony Survival Assay for Cells of Mouse Intestinal Mucosa Exposed to Radiation

Abstract

SummaryA microcolony technique for assaying the survival of small proportions of the clonogenic cells of the mucosa of the small intestine of mice is described. The radiosensitivity of intestinal crypt cells measured by the technique is the same as that measured by a macrocolony method. However, the microcolony technique has the special advantage of being useful for assaying cell survival after whole-body radiation.
