Liver fibrogenesisis chronic tissue damage characterized by an extracellular ac-cumulation of fibrillar matrix associated with continuous degradation and remod-elling. This scientific review describes current concepts on the pathophysiology of liver fibrosis, inflammation asa fundamental concept of liver fibrosis, mechanistic concepts of liver fibrosis, the role of mesenchymal stem cells (MSC) in liver injury, the functional effects of MSC secretome, the advantages of secretome ther-apy, and the latest research developments on MSC. The role of MSCs has been proven in many liver fibrosis studies involving experimental animals. However, it still requires further research for safety and efficacy aspects.
