Developmental stages and characteristics
Myeloblast | Dark Purple Rim of basophilic stippling Nucleoli Present | Fine Chromatin and few granules | |
Promyelocyte | Nucleoli Present | Fine Chromatin, Granules covering cell | |
Myelocyte | Oval or slightly indented nucleus | Clumpy Chromatin, granules | |
Metamyelocyte | kidney bean shape nucleus | Clumpy Chromatin, acidophilic granules | |
Band Neutrophil | Handband shaped nucleus | Clumpy Chromatin, acidophilic granules | |
Mature/segmented Neutrophil | 3-5 lobed nucleus , pinches in | Clumpy Chromatin, acidophilic granules | 40-75% |
Segmented Basophil | Mediate Allergic Reactions, Histamine | Deep purple granules covering cell | 0-2% |
Segmented Eosinophil | Activated by allergic reaction, Antihistamine | Red/Pink granuales | 1-7% |
Monoblast | light blue cytoplasm | eccentric nucleus | |
Promonocyte | gray-blue cytoplasm | oval/indented nucleus | |
Monocyte | ground glass gray blue cytoplasm | kidney bean shape/headband shape | Killer cells, phagocytosis 1-10% |
Lymphoblast | Dark blue boarder | round/oval nucleus | |
Prolymphocyte | thinner blue boarder | lighter blue cytoplasm | slightly condensed chromatin |
Lymphocyte | Small in size about 20-40 % | dense chromatin | sky blue/scant cytoplasm |
Order of Myeloid Cell Development | Myeloblast, Promyelocyte, Myelocyte, Metamyelocyte, Band Neutrophil, Mature/segmented |
