Regenerative Bandage Attracts Stem Cells to Wounds

Aug-22-16 A new stem cell-attracting “regenerative bandage” can help wounds heal up to four times faster.

The bandage, from a team at Northwestern Engineering, was designed with diabetics in mind, who often develop hard to heal, lower-limb ulcers or wounds. The bandage is made up of a polyethylene glycol that has been combined with a protein called SDF-1. This protein attracts stem cells to the site of the injury, which promote the creation of new blood vessels and speed healing. The bandage is liquid at room temperature, but will solidify to a gel consistency when exposed to body heat, and can also be cooled back to a liquid for easy removal from the skin.
