Caption

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.
