Reactive fibroblasts

WebFibroblast activation protein (FAP) is a transmembrane glycoprotein that is upregulated in cancer-related fibroblasts of human epithelial cancers and at sites of tissue remodeling such as fibrosis and wound healing. Radiolabeled FAP antibodies and inhibitors (FAPIs) have been developed and utilized for the PET imaging of FAP expression. 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.
