Liver fibrosis is a key pathological process in the progression of chronic liver disease to cirrhosis and even liver cancer.The occurrence of liver fibrosis is a highly integrated and dynamic pathological process result ing from the interactions of many cells and cytokines.The Notch signaling pathway is an evolutionarily conserved intercellular signal transduction mechanism that plays important roles in regulating the development and tissue renewal of multicellular animals.Multiple studies have shown that Notch signal transduction participates in the formation of liver fibrosis in a variety of ways.Therefore,this paper reviews the role of Notch signaling in cells involved in the formation of liver fibrosis to explain the function of this signaling pathway in liver fibrosis.
