(Ivanhoe Newswire) -- Each year, approximately 7.9 million bone fractures occur in the United States alone, costing an estimated $70 billion. Of these, 10 to 20 percent fail to heal. However, researchers at the University of North Carolina at Chapel Hill School of Medicine have discovered through an animal study that transplantation of adult stem cells enriched with a bone-regenerating hormone can help mend bone fractures that are not healing properly. The researchers found that stem cells...

(Ivanhoe Newswire) "“ Many bone fractures don't heal completely or properly, but this new model shows why fractures aren't healing properly and how they can be treated to restart the healing process and produce a strong healthy bone. About 5 to 10 percent of bone fractures the healing process doesn't succeed in fully repairing the bone, which leads to non-unions- failure of a fracture to unite and heal. Using an animal model mimicking a clinical non-union situation and a mathematical...

New models, reinforced by in vivo experimentation, show why 5-10% of bone fractures don't heal properly, and how these cases may be treated to restart the healing process. Results of the model, published September 2 in the open-access journal PLoS Computational Biology, may benefit the ageing population in which the occurrence of bone fractures is expected to rise substantially in the near future. In 5 to 10% of bone fracture cases, the healing process does not succeed in repairing the bone,...

CHAPEL HILL, N.C. - Medical researchers at University of North Carolina-Chapel Hill announced Monday that they have made strides in the technology to rebuild damaged bone tissue using stem cells. The research team, led by Dr. Anna Spagnoli, an associate professor of pediatrics at the university, derived the stem cells from bone marrow samples to locate and repair broken bones in mice. Now the work is poised to move to humans. "What we have done here is shown a reason to move to a...

In a study in mice, adult stem cells improved healing of fractured bones, U.S. researchers said. Senior study investigator Dr. Anna Spagnoli of the University of North Carolina in Chapel Hill said that the stem cells migrated to the fracture site and increased the bone and cartilage bridging the gap. Our study provided critical data needed to implement a novel therapeutic approach in patients with impaired fracture healing, Spagnoli said in a statement. If scientists can duplicate the...
