Lymphocytes

  • These cells are very variable in size. The smallest may be smaller than erythrocytes (down to ~5 µm in diameter) while the largest may reach the size of large granulocytes (up to 15 µm in diameter).
  • How much cytoplasm is discernible depends very much on the size of the lymphocyte. In small ones, which are the majority of lymphocytes in the blood, the nucleus may appear to fill the entire cell. Large lymphocytes have a wider rim of cytoplasm which surrounds the nucleus.
  • Both the nucleus and the cytoplasm stain blue (and darker than most other cell types in the blood).
  • The typical lymphocyte only contains the usual complement of cellular organelles. The appearance of lymphocytes may change drastically when they are activated (see below).
