More adult stem cell success to chew on. A new report describes how adult stem cells from dental pulp were used to regrow jaw bone for patients. An Italian research team used stem cells taken from the patients' own molar dental pulp, mixed with a collagen scaffold, to grow bone in the jaws of patients. For some people, bone in the jaw can shrink away after removal of molars, sometimes leading to loss of other teeth. These patients need a replacement procedure to maintain jaw integrity. Use of the adult stem cells allowed "complete regeneration of bone at the injury site."

The paper is published in the November issue of the open access journal European Cells and Materials.
