Reticular connective tissue Reticular connective tissue Reticular connective tissue is a type of connective tissue with a network of reticular fibers, made of type III collagen ("reticulum" = net or network). Reticular fibers are not unique to reticular connective tissue, but only in this type are they dominant. Reticular fibers are synthesized by special fibroblasts called reticular cells. The fibers are thin branching structures. Reticular connective tissue is found around the kidney, the spleen, and lymph nodes, Peyer's patches as well as in bone marrow. The fibers form a soft skeleton (stroma) to support the lymphoid organs (lymph node stromal cells, red bone
Soft-tissue sarcoma cancer cases each year. This may be because cells in soft tissue, in contrast to tissues that more commonly give rise to malignancies, are not continuously dividing cells. In 2006, about 9,500 new cases were diagnosed in the United States. Soft-tissue sarcomas are more commonly found in older patients (>50 years old), although in children and adolescents under age 20, certain histologies are common (rhabdomyosarcoma, synovial sarcoma). Around 3,300 people were diagnosed with soft-tissue sarcoma in the UK in 2011. "An earlier version of this article was taken from the US National Cancer Center's Cancer Information Service."
