Study Notes
Plasma Cell Origin and Distribution
- Primary origin of plasma cells is from B cells in the lymphoid organs, particularly in the germinal centers of secondary lymphoid organs.
- Shortly after their formation, plasma cells primarily home to the bone marrow, where they mature and produce large amounts of antibodies.
- Plasma cells comprise approximately 5% of all nucleated marrow cells in a healthy adult.
Test your knowledge about plasma cells and their migration to the bone marrow. Learn about the formation and persistence of plasma cells in the body, as well as their prevalence in the nucleated marrow cells.
