3 - Myelocytt (1000X)

• Stage 1 - Myeloblast
• Stage 2 - Promyelocyte
• Stage 3 - Myelocyte
• Stage 4 - Metamyelocyte
• Stage 5 - Band neutrophil
• Stage 6 - Segmented neutrophil

The myelocyte is characterized by:

• The nucleus has small dense spots of chromatin and contains no nucleoli
• The cytoplasm is lighter and with different types of grains (azurophilic and "specific" grains)
• The azurophilic grains contain myeloperoxidase, acid phosphatase and hydrolytic enzymes.
• The specific grains which are the mostabundant contain alkaline phosphatase and lysozyme.
