This composite flow cytometric panel illustrates the bone marrow of a newly diagnosed primary plasma cell leukemia patient demonstrating CD38 +, λ-a-restricted, CD20-plasma cells.

Multiple myeloma (MM) is a bone marrow cancer caused by clonal proliferation of plasma cells, and it is classified as a plasma cell dyscrasia. Over the last 20 years, there has been a dramatic ...

Clonal plasma cells in the bone marrow secrete free light chains into circulation. These light chains are part of immunoglobulins, also called antibodies. But in this disease, light chains misfold ...

Some of them become white blood cells, which are an important part of your body’s immune system. Plasma cells are a type of white blood cell. Normally, they make antibodies -- proteins to help ...
