Cell, plasma

Cell, plasma
A type of white blood cell that produces and secretes antibodies. A plasma cell is a fully differentiated lymphocyte in the B-cell (not the T-cell) lineage. As with most cell types, plasma cells can mutate to give rise to cancer. Plasma cell malignancies include multiple myeloma, Waldenstrom macroglobulinemia, and plasma cell leukemia.
