2 - Promyelocyte (1000X)
- Stage 1 - Myeloblast
- Stage 2 - Promyelocyte
- Stage 3 - Myelocyte
- Stage 4 - Metamyelocyte
- Stage 5 - Band neutrophil
- Stage 6 - Segmented neutrophil
The promyelocyte is characterized by:
- Lots of extended chromatin in the nucleus, as well as nucleoli.
- The cytoplasm is colored blue with blue-red (azurophilic) grains which are a type of lysosomes.
