Clinical Significance
The B-cell marker, CD19, is expressed in the B-cell lineage from pre-B cell stage up to mature post-germinal center B cells, and is absent in plasma cells and most plasma cell neoplasms. With the exception of some follicular dendritic cells and rare aberrant expression in carcinomas, CD19 is specific for the B-cell lineage.
