title: Tight junctions adjacent to tumor stromal interface in human invasive transitional cell carcinomas.
abstract: Tight junctions adjacent to the tumor stromal interface in invading neoplastic cells of human urinary bladder carcinomas were observed. Basal lamina, collagen and elastic fibers, and cellular debris were found next to the tight junctions. An association between microenvironment (i.e., tumor necrosis) of the invading neoplastic cells and tight junction locations was suggested.
