Caption: False-colour scannning electron micrograph (SEM) of a T-lymphocyte killer cell (green) attacking a large cancer tumour cell (pink & yellow). The T- lymphocyte, a white blood cell, must make intimate contact with the tumour cell. It does so by recognizing antigens on the tumour cell's surface. Following contact, the tumour cell undergoes structural changes that lead to its death. The tumour cell may survive, however, by budding off a number of blebs or blisters (seen here), which form a protective barrier between itself & the T- lymphocyte, preventing intimate contact. Magnification: x2500 at 35mm size, x5000 at 6x7cm size. Rossdale colouring. Original BW is M132/09M.
