because previous studies have strongly suggested that in acute tge diarrhea the epithelium is composed of relatively undifferentiated crypt-type cells , we speculate that high-affinity d-glucose carriers are lacking in normal crypt epithelial cells and that they are incorporated into brush-border membranes of jejunal enterocytes as the cells differentiate in the course of their migration from crypt to villus .
