Figure 2: Examples of crypt widths of individual colons from the TRANS. TRANS/AOM, AOM and control groups. Note that the AOM and control groups show similar crypt morphology whereas the majority of the crypts of the TRANS and TRANS/AOM groups show much larger crypt widths than the two former groups. Occasionally, aberrant crypt foci (ACF) were observed in AOM treated mice (arrow). Many crypts in the TRANS and TRANS/AOM remind of ACF (arrow heads).
