6.27 Lymph node medulla

Version française

Section of the medulla of a lymph node.

The following cells are labelled in the medullary cord and sinuses: reticular cells (R), lymphocytes (L), plasma cells (P), macrophages (Mac).

The antibody producing plasma cells are ovoid cells with a small spherical eccentrically located nucleus in a chromophilic cytoplasm. The staining of the cytoplasm is due to an abundance of ribosomes associated with a profuse network of endoplasmic reticulum cisternae. A small spherical lightly stained juxtanuclear area containing some plasma cells (P) is occupied by the Golgi apparatus.

Stain: H–E
Magnification: ×800
