Adult stem cells help heal broken bones

Adult stem cells are specialized cells with the ability to regenerate tissue in response to damage. However, many patients lack sufficient numbers of these cells and thus cannot heal properly.

Researchers have used adult stem cells in a few cases to improve fracture healing, but further studies were needed to show that this method was truly effective and safe before it can be pursued as a new treatment.

Now scientists at University of North Carolina at Chapel Hill have provided the scientific foundation for future clinical trials of this approach by demonstrating in animal models that these cells can be used to repair broken bones.

"This finding is critical to patients who lack the proper healing process and to individuals prone to broken bones, such as those with osteoporosis and the rare genetic condition known as brittle bone disease," said Dr. Anna Spagnoli, associate professor of pediatrics and biomedical engineering in the UNC School of Medicine and senior author on the study.
