Title: Scheme of reticular tissue in a lymph node
 
Description: Lymph node “stromal” 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 of lymphoblast
17 young monocyte
18 differentiating B lymphocyte
19 preplasmocyte
20 meshwork-forming reticular cell
21 retracting reticular cell after phagocytosis
