HeLa cells. Coloured immunofluorescent light micrograph (LM) of HeLa cancer cells. The triangular cells have been stained to reveal the microtubules (red) and actin filaments (green) of the cytoskeleton. HeLa cells were established in 1952 as the first human cell line to research cancer. The cells were named after Henrietta Lacks, from whose cervix they were obtained. HeLa cancer cells are used worldwide as they grow unusually well in the laboratory. Immunofluorescence is a staining technique which uses antibodies to attach fluorescent dyes to specific cell tissues. Magnification: x740 at 6x4.5cm size.
