WebSep 3, 2024 · Fibroblasts are metabolically active cells that play a central role in, not only matrix maintenance and remodeling and regulating ECM, but also in managing interstitial fluid volume and pressure, new tissue formation and wound healing. A fibroblast is a type of biological cell that synthesizes the extracellular matrix and collagen, produces the structural framework (stroma) for animal tissues, and plays a critical role in wound healing. Fibroblasts are the most common cells of connective tissue in animals.
