| myeloma cell | <haematology, oncology> Neoplastic plasma cell. The proliferating plasma cells often replace all the others within the marrow, leading to immune deficiency and frequently there is destruction of the bone cortex.

Bence Jones proteins are monoclonal immunoglobulin light chains overproduced by myeloma cells and excreted in the urine. Myeloma cell lines are used for producing hybridomas in raising monoclonal antibodies. (18 Nov 1997) |
