title: Migrating colonic crypt epithelial cells: primary targets for transformation.
abstract: It is widely believed that stem cells are the relevant target cells for colonic cell transformation. Evidence is presented that a proliferative transit daughter cell acquiring a mutant adenomatous polyposis coli gene during upward migration from the crypt base can develop retention abnormalities and permanence in the crypt, thus qualifying as a transformed clone which is retained in the colonic epithelium.
