Webb3.18.5.1.2.2 Fibroblasts. Fibroblasts are critical components of granulation tissue. Fibroblast accumulation begins 3–5 days after injury and may last up to 14 days. Following biomaterial implantation, fibroblasts undergo a response known as “activation,” characterized by a transition of quiescent cells into myofibroblast-like phenotype. Webb21 feb. 2024 · This process, known as fibrosis, leads to a build-up of stiff fibrotic tissue that interferes with the activity of the underlying organ. In healthy organs, fibroblasts lay down just enough collagen to maintain the integrity of the tissue ( D’Urso and Kurniawan, 2024 ). However, if the tissue begins to stiffen, these cells produce more ...
