COVID-19 is an emerging, rapidly evolving situation. Fibrocytes - markers, recruitment, and differentiation A few years ago tissue-resident fibroblasts were thought to be the only possible source of fibroblasts.  |  Cancer-associated fibroblasts (CAFs) in the stroma are considered to play important roles for gastric cancer proliferation, invasion, and fibrosis, but the source of CAFs and their interaction with cancer cells in the microenvironment have not been fully determined. Fibroblasts originate from mesenchymal stem cells or from fibrocytes (inactive form of fibroblasts). Yashoda Ramyajith Somarathna holds a B.Sc. 1. The main role of fibroblasts is to produce various extracellular matrix including proteoglycans, collagens, proteolytic enzymes, growth factors, and certain signalling molecules like cytokines. Tenoblasts typically occur in clusters, free from collagen fibres. They have been described in the liver and have been found to make up a small proportion (on the order of 5% of the total collagen-synthesizing population) of fibrogenic cells.
