Variability of cell proliferation in the proximal and distal colon of normal rats and rats with dimethylhydrazine induced carcinogenesis

Figure 4 Labelling indices of normal distal colon (ND) and DMH distal colon (DD) for the 5 compartments. ^aP < 0.05, ^bP < 0.0001 when labelling indices in the compartments of DMH distal colons were compared to those found in normal distal colons in the same compartments.
