Macroscopic visualization of tumors in <i>Hltf</i>-deleted colon.

Abstract

Alcian blue (1%) was topically applied to longitudinally opened colons from two different Hltf-deleted mice to highlight the borders of the individual tumors against the normal epithelium of the colon (upper panel) and each other (lower panel). The heterogeneity of the tumor burden in the distal colon/rectum is well demarcated by the Alcian blue stain.</p
