Fig 1. Immunohistochemical localization of ALDH1B1 in the colon of wild-type and ApcMin mice.

Fig 1

Expression of ALDH1B1 (brown stain) is confined to stem cell region of the normal colon (left panel) from wild-type mice (Apc(+/+)). In contrast, a colon polyp from ApcMin mice showed universal expression in the epithelial cells, with some staining in the stromal cells (right panel). ALDH1B1 expression exhibited cytosolic punctate pattern. (100x)
