This review systematically dissects the context-dependent roles of senescent cells in liver fibrosis, with a focus on hepatocytes, hepatic stellate cells (HSCs), liver sinusoidal endothelial cells (LSECs), Kupffer cells, and natural killer (NK) cells. Distinct populations of senescent cells emerge sequentially during different stages of fibrosis, exhibiting divergent kinetics and functional effects. The SASP, a dynamic cocktail composed of cytokines, chemokines, and proteases, remodels the intrahepatic microenvironment through immune cell recruitment, regulation of cell function, and modulation of ECM turnover. These effects vary depending on their molecular composition and disease context. Furthermore, we discuss emerging senescence-targeted therapeutic strategies to restore liver homeostasis.
