When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a technique employed by a University of Rochester research team keeps the stem cells in place, resulting in faster and better tissue regeneration.

The technique is similar to what has already been used to repair other types of tissue, including cartilage, but had never been tried on bone.
