Natural killer (NK) cells interacting with hepatoma cell (HepG2). Coloured scanning electron micrograph (SEM). NK cells ( red) of a healthy individual were cultured with HepG2 (liver cancer) cells. Natural killer cells are part of the innate immune system and specialised in recognition of tumour cells and their destruction. Magnification x 7000 at 10cm wide. Specimen courtesy of the Maini Lab.
