Granulation tissue fibroblasts
WebJun 6, 2012 · Active angiogenesis which is critical for the wound healing process, allows new capillaries to deliver nutrients including oxygen to the wound, and contributes to the proliferation of fibroblasts. In the granulation tissue, fibroblasts become activated and acquire a smooth muscle cell-like phenotype; they are consequently called myofibroblasts. WebDec 23, 2024 · Granulation tissue fibroblasts have elevated expression levels of α5 integrins (bind to Fn), yet lower levels of α1 integrins (binds to collagen and laminin). This finding potentially indicates a preference among granulation tissue fibroblasts for an Fn-rich matrix independently of cytokine treatment or overexpression (PDGF, IL-1β, TNFα, …
