Web1 Introduction. Circulating fibrocytes were first identified in 1994 as a result of studies in a model system of wound repair, and defined by their growth characteristics and unique surface phenotype ( 1, 2 ). Fibrocytes produce collagen and other matrix proteins, but they also circulate in the peripheral blood and express cell surface markers ...

Myofibroblasts are fibroblasts that contain actin filaments associated with dense bodies; hence, they resemble smooth muscle cells. It is believed that myofibroblasts play a role in contraction of the wound during healing. Reticular Cells Reticular cells are similar in appearance to the fibrocyte .

Thus, studying subjects with HPS provides a unique opportunity to evaluate a ...
The lack of a fibrocyte-specific marker has posed challenges to the investigation of this cell type in vivo. As a result, different strategies have been employed to study the contribution of fibrocytes to injury and disease models. These include: 1) immunolabeling, 2) labeling of circulating cells, 3) transgenic … See more Few studies have attempted to determine the amount of collagen produced by fibrocytes relative to overall collagen production during fibrosis. In vitro, cultured pulmonary fibroblasts … See more To properly evaluate studies reporting fibrocyte-derived myofibroblasts, one must first understand the criteria for a cell to be identified as a myofibroblast.
