Moreover, interesting comparisons with other pathologies are emerging involving the influence of circulating mesenchymal precursor cells on tissue responses. The fibrocytes secrete matrix proteins and inflammatory cytokines, activate local fibroblasts to proliferate and increase extracellular matrix production, and promote angiogenesis, and because fibrocytes are contractile, they also help wound contraction. Fibroblasts are considered major contributors to the process of fibrogenesis and the progression of matrix deposition and tissue distortion in fibrotic diseases such as Pulmonary Fibrosis.  |  These cells mainly contribute to wound repair and fibrosis due to their ability of differentiation into their active form -fibroblasts. Fibrocytes - markers, recruitment, and differentiation A few years ago tissue-resident fibroblasts were thought to be the only possible source of fibroblasts. 5 However, the scenario continues toal5 fibroblasts, pericytes, phenotypic transition of endothelial cells, phenotypic modulation of vascular smooth muscle cells, and recruitment of circulating multipotent monocytes and fibrocytes. Additionally, fibrocytes also play a role in certain immune responses as well as the deposition of collagen fibres. These cells have an ellipsoidal, flattened, large nucleus with finely distributed chromatin and also contain 1-2 nucleoli. Lin J, Jiang Z, Liu C, Zhou D, Song J, Liao Y, Chen J. Moreover, another difference between fibroblast and fibrocyte is that fibroblasts mainly produce extracellular components such as proteoglycans, collagens, proteolytic enzymes, growth factors and certain signalling molecules like cytokines, while fibrocytes help in certain immune response, deposition of collagen, and wound repair.
