Scientists from Imperial College London have used the blend of the two commonly used drugs to heal the spinal fractures. In an experiment on the rats, researchers found that the two commonly used drugs are effective to recover from the fractures by triggering the release of stem cells from the bone marrow. The research revealed that the drugs are effective to heal different types of bone fractures, including the spine, hip, and leg, to aid healing after surgery or fractures. The drugs allowed the bone marrow of healthy rats to excrete the mesenchymal stem cells, a type of cell that helps to repair bone fractures. After its successful trial in rats, the researchers are now planning to test the drug combinations in humans.
