44Normal Cells of the Blood and Hematopoietic OrgansEosinophilic Granulocytes (Eosinophils)Eosinophils arise from the same stem cell population as neutrophils andmature in parallel with them. The earliest point at which eosinophils canbe morphologically defined in the bone marrow is at the promyelocytestage. Promyelocytes contain large granules that stain blue–red; not untilthey reach the metamyelocyte stage do these become a dense populationof increasingly round, golden-red granules filling the cytoplasm. TheCharcot–Leyden crystals found between groups of eosinophils in exudatesand secretions have the same chemical composition as the eosinophilgranules.The nuclei of mature eosinophils usually have only two segments.Diagnostic Implications. In line with their function (see p. 5) (reactionagainst parasites and regulation of the immune response, especiallydefense against foreign proteins), an increase of eosinophils above 400/µlshould be seen as indicating the presence of parasitosis, allergies, andmany other conditions (p. 124).Basophilic Granulocytes (Basophils)Like eosinophils, basophils (basophilic granulocytes) mature in parallelwith cells of the neutrophil lineage. The earliest stage at which they can beidentified is the promyelocyte stage, at which large, black–violet stainedgranules are visible. In mature basophils, which are relatively small, thesegranules often overlie the two compact nuclear segments like blackberries.However, they easily dissolve in water, leaving behind faintly pinkstained vacuoles.Close relations of basophilic granulocytes are tissue basophils or tissuemast cells—but these are never found in blood. Tissue basophils have around nucleus underneath large basophilic granules.Diagnostic Implications. In line with their role in anaphylactic reactions(p. 5), elevated basophil counts are seen above all in hypersensitivity reactionsof various kinds. Basophils are also increased in chronic myeloproliferativebone marrow diseases, especially chronic myeloid leukemia(pp. 117, 120).
