Stem cells 'could treat non-healing bone fractures'
Monday 6th June 2011
A stem cell treatment could be used to treat bone fractures that are failing to heal normally, a study has indicated.
Adult stem cells enriched with insulin-like growth factor (IGF-I) were transplanted into non-healing bones in mice by researchers from the University of North Carolina.
Researchers then used computed tomography (CT) scans to track the speed of healing in the mice, according to the study to be presented at the Endocrine Society's 93rd Annual Meeting.
Principal investigator Anna Spagnoli said: "We found that stem cells empowered with IGF-I restored the formation of new bone in a mouse lacking the ability to repair broken bones. This is the first evidence that stem cell therapy can address a deficiency of fracture repair."
This follows research published in journal Molecular Pharmaceutics, which revealed that joint replacement failures could be detected early on with the implementation of a new test involving a polymer-based imaging.
