Macrophage. Coloured scanning electron micrograph (SEM) of a macrophage white blood cell at the site of a skin wound. Macrophages are cells of the body's immune system. As well as fighting off micro-organisms,they play an important role in wound healing. Macrophages arrive at a wound after other immune cells have started eliminating any micro-organisms. They release chemicals that attract other cells to the area,and that start the reconstruction of tissues. They stimulate fibroblasts,cells that produce collagen,and initiate the growth of vascular tissue | |
