Reticular connective tissue is a type of connective tissue [1] with a network of reticular fibers, made of type III collagen [2] (reticulum = net or network). Reticular fibers are not unique to reticular connective tissue, but only in this tissue type are they dominant. [3] Reticular fibers are synthesized by special fibroblasts called ...
Reticular fibers, reticular fibres or reticulin is a type of fiber in connective tissue [1] composed of type III collagen secreted by reticular cells. [2] They are mainly composed of reticulin protein and form a network or mesh.
Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs. Reticular cells are found in many organs, including the spleen, lymph nodes and kidneys. They are also found within tissues, such as lymph nodules.
In immunology, the mononuclear phagocyte system or mononuclear phagocytic system (MPS) also known as the macrophage system is a part of the immune system that consists of the phagocytic cells [1] located in reticular connective tissue. The cells are primarily monocytes and macrophages, and they accumulate in lymph nodes and the spleen.
This type of connective tissue is found mostly in the reticular layer (or deep layer) of the dermis. [3] It is also in the sclera and in the deeper skin layers. Due to high portions of collagenous fibers, dense irregular connective tissue provides strength, making the skin resistant to tearing by stretching forces from different directions.
Thin reticular fibers (reticulin) of reticular connective tissue form a supporting meshwork inside the node. [5] These reticular cells also form a conduit network within the lymph node that functions as a molecular sieve, to prevent pathogens that enter the lymph node through afferent vessels re-enter the blood stream.

The presence of neurofibrillary tangles in the brain is one of the key hallmarks of Alzheimer’s disease. These irregular clumps of protein are closely associated with disease progression.
Fibrocytes usually do not leave the connective tissue. Reticular cells are usually larger than fibrocytes. Reticular cells are the fibrocytes of reticular connective tissue and form a network of reticular fibers. Adipocytes are fat cells that are fixed cells in loose connective tissue. Their main function is the storage of lipid.
