Smart bandaids

Researchers developed a bandage that teaches damaged skin where to grow new blood vessels.  Living cells are embedded in gel on a sort of printed circuit in the bandage and they emit growth factor.  After a week, the new capillaries followed the template lines of the"microvascular stamp".  Getting the distribution system into place, vascularization, is a key to healing and creating skin, muscle and bones.  Photo shows results when placed against a developing chicken embryo.
