Question

Morphologic variants of plasma cells do NOT include?

1) Mature plasma cells
2) Plasmablasts
3) Proplasmacytes
4) Myeloblasts

Answer 1

Morphologic variants of plasma cells do not include myeloblasts. The variants are mature plasma cells, plasmablasts, and proplasmacytes.

Step-by-step explanation:

Morphologic variants of plasma cells do not include myeloblasts. The morphologic variants of plasma cells are:

1. Mature plasma cells: These are fully differentiated plasma cells that have the ability to secrete soluble antibodies.
2. Plasmablasts: These are intermediate stage cells between B cells and mature plasma cells. They have a large amount of cytoplasm packed with rough endoplasmic reticulum.
3. Proplasmacytes: These are also intermediate stage cells that are precursors to mature plasma cells.

Myeloblasts, on the other hand, are precursor cells of myeloid stem cells that differentiate into granulocytes, such as neutrophils, eosinophils, and basophils, not plasma cells.
