Description
A confocal micrograph of a healing wound on the
surface of a chick embryo limb bud about one hour
after wounding. The leading edge of the outer
surface epithelium cells (red), shown by the
curved line, forms a cable (made up of a protein
called actinomyosin, stained green) which draws
the epithelium over the underlying tissue to close
the wound. In embryos wounds heal without a scar. Biomedical Image Awards 1998.
