Fibroblasts are the primary cells responsible for the extracellular matrix (ECM) production and maintenance in connective tissues. They play a central role in fibrosis, a condition characterized by excessive ECM accumulation and cellular proliferation. Fibroblasts can transform into myofibroblasts, which exhibit enhanced ECM production and contractile properties, contributing to wound healing and fibrosis. Fibroblasts also participate in inflammation, angiogenesis, and cancer progression. The activation of fibroblasts involves developmental signaling programs and can be influenced by various chemical signals such as cytokines, chemokines, and growth factors. Targeting fibroblast biology is a promising approach for treating fibrotic disorders, with potential therapies including endostatin, vitamin D3, epigenetic modifications, and Wnt-like signaling pathway interventions. Fibroblasts' multifaceted roles and their interactions with other cell types highlight the complexity of fibrosis and the need for personalized medicine strategies.Fibroblasts are the primary cells responsible for the extracellular matrix (ECM) production and maintenance in connective tissues.
