Sequential and morphological analyses of aberrant crypt foci formation in mice of differing susceptibility to azoxymethane-induced colon carcinogenesis

Abstract excerpt

Aberrant crypt foci (ACF), putative preneoplastic lesions, are early morphological changes induced by the colon carcinogen azoxymethane (AOM). Although inbred mice differ markedly in their susceptibility to AOM carcinogenesis, we have previously shown that ACF develop in both resistant and sensitive mouse strains after AOM treatment. The purpose of this study was to examine the sequential development and identify...
