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. 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;
