Immunofluorescent Light Micrograph of fibroblast connective tissue cells among melanoma skin cancer cells, recovered from a tumour. Cell nuclei stain blue; cytoplasm is orange. At centre right, a large fibroblast cell is seen: it forms connective tissue in support of other cells, and at sites of tissue damage. Actin fibres (green) surround it & other fibroblast cells, which help to provide this supportive network. Small malignant melanoma cells occur at left. Immunofluorescence is a staining technique which uses antibodies to attach fluores- cent dyes to specific tissues and molecules in the cell. Magnification x200 at 35mm, x375 at 6x4.5cm.
