Electron micrograph of B-lymphocyte blood cell

B-lymphocyte. Coloured scanning electron micrograph of a B-lymphocyte white blood cell. The cell's surface is covered with tiny ridges and projections called microvilli, which help it bind to target proteins. B-cells account for 10% of the body's lymphocytes. On encountering a foreign antigen, such as a bacterial surface protein, the immature B-cell either divides into a number of plasma cells, which produce antibodies that kill the invader, or it matures into a memory cell. Memory cells remain in the body for years, giving immunity to the original pathogen. Magnification x5500 at 6x7cm size. Magnification x2750 at 35mm size
