Blood - Neutrophil

(Stain - Haematoxylin Eosin)

• neutrophil granulocyte
• about 3% eosinophils (>0% - 5%) of leukocyte population in blood smears.
• common leukocyte in blood smears, about 60% neutrophils (50% - 70%)
• nucleus is divided into 3-5 lobes connected by thin strands of chromatin.
• lobe number increases with cell age (old cells up to 7 lobes).
• contain two types of granules.
  • primary granules (A granules) contain lysosomal enzymes and are probably primary lysosomes, though they are larger (0.4 µm) than the typical primary lysosome.
  • secondary granules (B granules), the specific granules of the neutrophils, contain enzymes with strong bactericidal actions. These granules stain only weakly if they are at all visible ("neutral").
