Distribution of TGF-α expression throughout colon crypts in incident sporadic colorectal adenoma cases and controls, MAP II. Cells from the base to the opening of the crypt (proliferative zone to zone of differentiation) are presented on the X axis; Y axis, batch-standardized staining optical density; circles, measures in cases; squares, measures in controls; points, the average of all patients’ hemicrypts at a standardized crypt section or location; smoothed lines, the best fit for the data.
