HeLa cells

This image shows HeLa cells. HeLa cells are an immortal human cancer cell line derived from a cancerous tumor of Henrietta Lacks. These cells have unique properties that allow them to continually grow outside the body and have been used to derive many cell lines for cell culture experiments. This image has been produced by fluorescently staining the cells with Alexafluor 488 to detect alpha tubulin, TRITC phalloidin marks actin in the cells cytoskeleton and DAPI marks the cell nucleus. The image has been inverted and adjusted using imaging software.
