Myofibroblasts in liver
WebJun 23, 2013 · Myofibroblasts are characterized by expression of α-smooth muscle actin (α-SMA) and type I collagen, and in all clinical and experimental liver fibroses serve as a major source of the ECM. Thus, activation and proliferation of hepatic myofibroblasts is a key mechanism in the development of liver cirrhosis. WebMar 12, 2024 · In liver fibrosis, myofibroblasts derive from HSCs and as yet undefined mesenchymal cells. We aimed to identify portal mesenchymal progenitors of myofibroblasts. Approach and Results Portal mesenchymal cells were isolated from mouse bilio-vascular tree and analyzed by single-cell RNA-sequencing.

It is likely that the sources of liver myofibroblasts vary by injury type; however, liver myofibroblasts share more common features than those that differ.
WebJan 1, 2024 · Endogenous portal fibroblasts, fibrocytes, bone marrow-derived cells, and liver parenchymal cell-derived myofibroblasts that undergo epithelial-mesenchymal transition (EMT) give rise to a significant percent of myofibroblasts in the fibrotic liver. Different cell types activate myofibroblasts depending on the etiology of liver fibrosis (6). WebJan 10, 2024 · The majority of the studies aiming at identifying the origin of myofibroblasts have suggested that most likely HSCs are the main source of myofibroblasts in the injured liver.7–9However, this topic is still controversial and other than HSCs several other cell types have been proposed to give rise to myofibroblasts.
WebAug 17, 2024 · Liver fibrosis, SMA + myofibroblasts and the ductular reaction were assessed in WT, EphA2 −/− and EphA4-Fc treated TAA mice. Results : Quantitative polymerase chain reaction (Figure 1 a) and immunohistochemistry (Figure 1 b) analyses confirmed an upregulation of EphA2 following 1 week of TAA treatment and identified … In many organs like liver, lung, and kidneys, they are primarily involved in fibrosis. In the wound tissue they are implicated in wound strengthening by extracellular collagen fiber deposition and then wound contraction by intracellular contraction and concomitant alignment of the collagen fibers by integrin-mediated pulling on to the collagen bundles. Pericytes and renal mesangial cells are some examples of modified myofibroblast-like cells.
