-
Myeloblast
- large, round to irregularly shaped cell
- finely stippled nuclear chromatin/lacey
- one or more prominent nucleoli
-
Progranulocyte (aka promyelocyte)
- large, round to irregularly shaped cell
- more cytoplasm than myeloblast
- nucleus round to oval
- cytoplasm - light blue-gray with scattered, small red/purple granules (primary granules)
- nucleoli are absent or indistinct
- chromatin becoming coarse
-
Myelocyte
- smaller than progranulocyte
- nucleus is usually round, may be beginning to indnet
- chromatin beginning to clump
- non specific (primary granules) no longer visible
- secondary (larger) cytoplasmic granules may be visible depending on type of myelocyte
- cytoplasm less basophilic
-
Metamyelocyte
- similar to myelocyte except...
- cytoplasm clear to slightly granular
- nucleus indents to become kidney bean shaped, mitosis no longer occurs
- chromatin coarse with clumps
-
Bands
- nucleus indents even more
- S-shaped or horse-shoe shape are common with parallel sides
- cytoplasm clear to slightly granular
-
Segmented neutrophil/eosinophil/basophil
- mature if nuclear membrane is no longer smooth
- nuclear width becomes irregular, or lobes present
- cytoplasm clear to slightly granular
