What do bone marrow cells look like as they differentiate?
What does this show?
What does this show?
erythroblast (pronormoblast). Erythroblasts are
large cells, with large centrally-placed, round nuclei with dispersed nuclear chromatin (often with one or
more nucleoli visible) and a scant amount of deeply basophilic cytoplasm.

What does this show?
myeloblast, which in normally accounts for less than
1% of the total marrow cellularity. The morphologic features of myeloblasts have been described
above. Morphologically, when compared to erythroblasts, the nuclei of myeloblasts are not as perfectly
round and often touch the edge of the cell (rather than being centered) and their cytoplasm is not quite
as basophilic (but these are subtle features).

What does this show?
myelocyte. It is at the myelocyte stage that cells begin to
develop specific differentiation. In cells destined to become neutrophils, the primary granules of the
promyelocyte are replaced by pink-staining granules typical of neutrophils.
