The regulation of cell proliferation and differentiation in intestinal epithelium. II. A quantitative histochemical and autoradiographic study after low doses of X-irradiation

To investigate the biochemical mechanisms involved in the regulation of cell proliferation and differentiation the intestinal epithelium has been chosen because of the regular distribution of proliferative-, non-dividing maturing- and functional cells along the crypt and villus. The effect of low doses of irradiation (50-400 R) which selectively...
