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 ...
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.

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 fibers crosslink to form a fine meshwork (reticulin).
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.
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.

The basement membrane, also known as base membrane, is a thin, pliable sheet-like type of extracellular matrix that provides cell and tissue support and acts as a platform for complex signalling. [ 1 ] [ 2 ] The basement membrane sits between epithelial tissues including mesothelium and endothelium , and the underlying connective tissue.
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.
