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.
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.

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.
Connective tissue is one of the four primary types of animal tissue, a group of cells that are similar in structure, along with epithelial tissue, muscle tissue, and nervous tissue. [1] It develops mostly from the mesenchyme , derived from the mesoderm , the middle embryonic germ layer . [ 2 ]
A reticular cell is a type of fibroblast that synthesizes collagen alpha-1(III) and uses it to produce extracellular reticular fibers.Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs.
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.
The reticular dermis is the lower layer of the dermis, found under the papillary dermis, composed of dense irregular connective tissue featuring densely-packed collagen fibers. It is the primary location of dermal elastic fibers. [2] The reticular region is usually much thicker than the overlying papillary dermis.
