Scheme of reticular tissue in lymph node

Lymph node stroma does not contain stromal cells but instead the reticular meshwork is build by reticular cell types, macrophages and lymphoid cells and myeloid cells. Route (A) in the scheme represents morphological differentiation path from B lymphocytes to plasma cells. 1 endothelial cell (littoral cell) of sinus-like capillary ; 2 (large) lymphocytes ; 3 phagocytising reticular cell; 4 monocyte; 5 small true capillary; 6 endothelial cell lining the capillary; 7 differentiating B lymphocyte or young plasma cell; 8 diapedesis of lymphocyte through wall of capillary; 9 mature plasma cell; 10 phagocytising littoral cell; 11 diapedesis of phagocytising reticular cell through wall of sinus; 12 retracted littoral cell after phagocytosis; 13 small lymphocyte; 14 differentiating B lymphocyte or young plasma cell; 15 macrophage; 16 blast cell or2 lymphoblast ; 17 young monocyte; 8 differentiating B lymphocyte; 19 preplasmocyte; 20 meshwork-forming reticular cell; 21 retracting reticular cell after phagocytosis
