Bladder cancer. Immunofluorescent light micrograph of cells cultured from squamous carcinoma of the bladder. Nuclei stain blue, cytoplasm red & cell connections green. Cell-cell adhesive contacts have been disrupted by culturing the cells with antibody against a certain cell adhesion molecule. Absence of such molecules is linked to the ability of tumour cells to metastasize. Bladder carcinoma is a malignant cancer, more common in men than women, & more common amongst smokers & workers in the dye & rubber industries. Immunofluorescence is a staining technique using antibodies to attach fluorescent dyes to specific tissues and molecules within the cell. Magnification: x187 at 35mm size.
