Watching Wounds

When we’re wounded, our bodies rush to repair the damage. First, there’s a blood clot that forms quickly and acts as a temporary seal. Then follows the more gradual process of angiogenesis – the growth of new blood vessels to replace those that are injured. This image is of a wound healing on a mouse. It was captured using a new form of fluorescence microscopy, which involves staining the tissue with chemicals that make it fluoresce, and then taking a picture that shows only the fluorescence. At the top is the blood clot in the open wound, while the strands beneath are newly grown capillaries [the smallest blood vessels] extending into the muscle. This technique enables us to understand the complex mechanisms of wound healing better than ever before.
