Though similar to healthy cells, cancer cells often display unique antigens on their surface, which can be exploited to develop cancer immunotherapies.
Since cancer cells bear very specific antigens on the surface, the corresponding antibodies bind to these molecules and thus inhibit tumor growth.
Although myeloma is, like leukemias and lymphomas, a cancer involving white blood cells known as lymphocytes, myeloma cells don't traditionally express CD19 on their surface because they arise from the most mature type of lymphocytes — plasma cells.
