Expression of syndecan-1 in normal colonic epithelium and colon adenocarcinomas. a, immunohistochemical staining for syndecan-1 in normal colon. b-c, syndecan-1 staining of colon adenocarcinomas is lost in correlation with tumor differentiation status. d, example of a moderately differentiated adenocarcinoma with strong stromal staining for syndecan-1 and moderate staining of the tumor. e, f, contiguous sections of the same tumor stained for syndecan-1, (e), or fascin, (f), demonstrating strong staining for fascin in the stroma (arrowed). The tumor cells are negative for fascin and syndecan-1. Isolated strongly fascin positive cells correspond to dendritic and vascular endothelial cells and provideinternal positive controls for the fascin staining.
