HeLa cell. Coloured scanning electron micrograph (SEM) of a cultured Hela cell (centre) on MDCK kidney cells (background). HeLa cells are a continuously cultured cell line of human cancer cells, which are immortal and so thrive in the laboratory. Numerous microvilli (string-like) can be seen, which cancer cells use to enable them to move around and spread (metastasise) from one area to another. MDCK cells are a strain of cultured, normal kidney epithelial cells.
About the Artist -
Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
