| - Primary follicles contain small resting naive B cells | |
| - Follicular dendritic cells (FDCs) | |
| Germinal center | - B lymphocytes in several stages of development and maturation |
| - T lymphocytes | |
| - Follicular dendritic cells (FDCs) | |
| - Tingible body macrophages | |
| Interfollicular cortex Paracortex | Dominant T lymphocyte areas |
| - T lymphocytes | |
| - B lymphocytes | |
| - Fibroblastic reticular cells (FRCs) | |
| - Interdigitating dendritic cells | |
| - High endothelial venules (HEV) | |
| Medullary cords | - Lymphocytes |
| - Plasma cells | |
| - Fibroplastic reticular cells (FRCs) | |
| - Macrophages | |
| Sinuses (subcapsular, transverse, paracortical, medullary) | - Macrophages |
| - Fibroblastic reticular cells (FRCs) |
