    Abstract
    The variation in migration rates of cells within the small intestinal epithelium was studied over a 24-hr period at 3-hr intervals (migration of cells was studied independently for the crypts and the villi using the changing distributions of [3H]TdR labelled cells as an indicator of cell migration). Clear changes in the rates of cell movement were observed during a 24-hr period for both crypt and villus epithelium. The rates of cell migration in these two compartments did not correlate well with the exception of samples taken at 18.00 hours. At this time of day there appeared to be no cell movement at all in either crypts or villi. There was not a good correlation between the migration velocity throughout the day and the changes in the number of mitoses. It is proposed that mitotic rates do not directly govern migration rates but that the converse may be true. Further, the lack of correlation between crypt and villus migration rates at any time of day suggest that the mechanisms controlling all movement in these two regions of small intestinal epithelium may be different.
