Notes - Approximate scale information: 10 m - The morphological characteristics of the hematopoietic cells are shown as seen in a Wright's stain, May-Giemsa stain or May-Grunwald-Giemsa stain. Alternative names of certain cells are indicated between parentheses. - Certain cells may have more than one characteristic appearance. In these cases, more than one representation of the same cell has been included. - Together, the monocyte and the lymphocyte comprise the agranulocytes, as opposed to the granulocytes (basophil, neutrophil and eosinophil) that are produced during granulopoiesis. - B., N. and E. stand for Basophilic, Neutrophilic and Eosinophilic, respectively - as in Basophilic promyelocyte. For lymphocytes, the T and B are actual designations. [1] The polychromatic erythrocyte (reticulocyte) at the right shows its characteristic appearance when stained with methylene blue or Azure B. [2] The erythrocyte at the right is a more accurate representation of its appearance in reality when viewed through a microscope. [3] Other cells that arise from the monocyte: osteoclast, microglia (central nervous system), Langherhans cell (epidermis), Kupffer cell (liver). [4] For clarity, the T and B lymphocyte are split to better indicate that the plasma cell arises from the B-cell. Note that there is no difference in the appearance of B- and T-cells unless specific staining is applied.
