Leukopoiesis & Functions
Stage | Cell Formed/Phase | Cell Characteristics |
---|---|---|
First Stage of Myeloid Cell Development | Myeloblast Phase | Finely reticular nuclear chromatin, Light staining nuclei, Small rim of basophilic stippling w/ NO granules, & Auer Rods present |
Second Stage of Myeloid Cell Development | Promyelocyte Phase | Chromatin more condensed, Nucleoli present w/round nuclear shape, Cytoplasm pale blue grey & Prominent granules present all over the cell & nucleus |
Third Stage of Myeloid Cell Development | Myelocyte Phase | Specific cytoplasmic granulation, Clumped chromatin, Nucleus more oval & NO nucleoli |
Fourth Stage of Myeloid Cell Development | Metamyelocyte Phase | Last stage of proliferative. Nucleus starts to form kidney bean shaped, Chromatin dense or clumped, Specific granulation becomes most distinguishing feature |
Fifth Stage of Myeloid Cell Development | Band Cell | Final maturation stage before segments of nucleus form, Elongated nucleus |
Last Stage of Myeloid Cell Development | Segmented Mature Cell | Several lobed nucleus w/ threadlike attachments, Specific granulation seen |
First Stage of Monocytic Cell Development | Monoblasts | Central or eccentric nucleus, may show folding. Cytoplasm is agranular, stains |
Second Stage of Monocytic Cell Development | Promonocytes | |
Last Stage of Monocytic Cell Development | Monocytes |
