Reticular connective tissue is produced by modified fibroblasts called reticular cells. The reticular tissue is limited to certain sites in the body, such as internal frameworks that can support lymph nodes, spleen, and bone marrow. Their nuclei are typically large and lightly stained (H&E) and the cytoplasm may be visible amongst the cells which are housed within the network of reticular fibres. Pigment tissue is a cellular connective tissue rather than a fibrous non-living connective tissue and has many melanin-containing connective tissue cells.

A reticular connective tissue is a connective tissue with a vast network of reticular fibres. The cells that make the reticular fibers are fibroblasts called reticular cells. Note the relative size of the different cell types, their shapes, amount of rough ER and variously sized granules and inclusions. These produce reticular fibers arranged in an interlaced network (reticulum), similar to dense irregular connective tissue. Reticular tissue provides a very delicate meshwork that serves as a scaffold to other tissues and also supports other cells and tissues.

[1] Reticular connective tissue is a type of connective tissue with a network of reticular fibers, made of type III collagen (reticulum = net or network). Connective tissue is found between other tissue types and organs. The reticular fibres are mostly made up of type III collagen (100-150 nm in diameter), which is produced by reticular cells, which are unique fibroblasts. connective tissue proper, cartilage, bone, blood. Connective tissues originate from embryonic mesenchyme and are present throughout the body except inside the brain and spinal cord. red bone marrow, spleen, and lymph node stromal cells. Adipose, or fat, tissue serves as a cushion for various organs and as a fat reservoir. Reticular Connective Tissue Function.

Connective tissue, as the name implies, is a term given to several different tissues of the body that serve to connect, support and help bind other tissues in the body. The lamina propria, which supports the epithelium, is a layer of reticular connective tissue with elastin, reticulin, and collagen fibers, lymphocytes, plasma cells, and eosinophilic granulocytes, as well as lymphatics and capillaries. Reticular cells has number of cytoplasmic processes which are interconnected to form reticular network. Reticular cells are fibroblasts specialized to synthesize reticular fibers. Reticular connective tissue forms a flexible 'skeleton' or internal framework, that can support many free blood cells (largely lymphocytes) in lymph nodes, the spleen, and red bone marrow. 2.
