Follicular dendritic cells are cells of the immune system found in primary and secondary lymph follicles of the B cell areas of the lymphoid tissue. Unlike dendritic cells, FDCs are not derived from t
This is an isolated Follicular Dendritic Cell cultured on collagen. It shows a cell body and numerous dendritic cell processes interdigitating with one another and with dendrites of adjacent FDCs to form a network. This network traps antigen in the form of immune complexes and helps initiate an antibody response by B cells
Histologic comparison of cell types in a germinal center, H&E stain: - Centrocytes are small to medium size with angulated, elongated, cleaved, or twisted nuclei. - Centroblasts are larger cells containing vesicular nuclei with one to three basophilic nucleoli apposing the nuclear membrane. - Follicular dendritic cells have round nuclei, centrally located nucleoli, bland and dispersed chromatin, and flattening of adjacent nuclear membrane.
The lymphatic system, or lymphoid system, is an organ system in vertebrates that is part of the immune system and complementary to the circulatory system. It consists of a large network of lymphatic v
