Reticular connective tissue is a type of connective tissue.[1] It has a network of reticular fibers, made of type III collagen.[2] Reticular fibers are not unique to reticular connective tissue, but only in this type are they dominant.[3]
Reticular fibers are synthesized by special fibroblasts called reticular cells. The fibers are thin branching structures.
Reticular connective tissue is found around the liver, the kidney, the spleen, and lymph nodes, as well as in bone marrow.[4]
The fibers form a soft skeleton (stroma) to support the lymphoid organs (lymph node stromal cells, red bone marrow, and spleen).
Adipose tissue is held together by reticular fibers.
They can be identified in histology by staining with a heavy metal like silver or the PAS stain that stains carbohydrates.
Reticular connective tissue resembles areolar connective tissue, but the only fibers in its matrix are reticular fibers, which form a delicate network along which fibroblasts called reticular cells lie scattered. Although reticular fibers are widely distributed in the body, reticular tissue is limited to certain sites. It forms a labyrinth-like stroma (literally, "bed or "mattress"), or internal framework, that can support many free blood cells (large lymphocytes) in lymph nodes, the spleen, and red bone marrow.
There are more than 20 types of reticular fibers. In Reticular Connective Tissue type III collagen/reticular fiber (100-150 nm in diameter) is the major fiber component. It forms the architectural framework of: liver, adipose tissue, bone marrow, spleen and basement membrane, to name a few.
