Research has shown that tweaking a certain group of multipotent stem cells - mesenchymal stem cells - with a hormone called interferon (IFN) in our body, might stop osteoporosis and promote bone growth.
The research dept of McGill university health centre states that IFN can repair bones affected by osteoporosis. According to the scientists IFN gamma itself would be efficient drug for osteoporosis.
