The powder, dubbed "pixie dust" has been developed by scientists using pig bladders.
It makes the cells to replace the damaged body part.
Scientists created the powder at America's Pittsburgh University. Cells from a pig bladder lining that was scraped and the remaining tissue was put in acid.
The powder was created by taking away the cells that form scars while those cells that tell the body to grow normally were kept.
After the tissue was removed from the acid, it is turned into powder that patients applied in their wound.
The Sun quoted chief researcher Stephen Badylak as saying, "I think within ten years we will re-grow bones and promote the growth of functional tissue around those bones. And that is a major step towards eventually doing an entire limb."
