1. Antibody secreting cells (ASC)- refers to proliferating plasmablasts and nonproliferating plasma cells.
2. Plasmablasts- Dividing ASC with migratory potential which may further mature into plasma cells.
3. Plasma cells (PC) - Terminally differentiated, non-replicating ASC able to secrete large amounts of antibodies.
