| Abstract: | Cell-to-cell attachments or associations in expermentally induced sarcoma of chicken embryo lethal orphan virus (avian adenovirus) origin were studied in hamsters by electron microscopic examination. In many instances, the neoplastic cells seemed to be held together either by desmosome-like structures or an "interlocking" of their apposing plasma membranes. Less frequently, the cells were attached by button-like projections between the cell surfaces. Only rarely, interdigitation occurred between filopodial processes of cell surface of adjoining cells. |
