Granulation tissue fibroblasts
WebCutaneous tissue repair aims at restoring the barrier function of the skin. To achieve this, defects need to be replaced by granulation tissue to form new connective tissue, and epithelial wound closure is required to restore the physical barrier. Different wound-healing phases are recognized, start … Granulation tissue is composed of tissue matrix supporting a variety of cell types, most of which can be associated with one of the following functions: • formation of extracellular matrix; • operation of the immune system; • vascularisation;
