Scientists abroad have succesfully tried to grow human bones from stem cells in fat and have implanted a one inch bone in mice. The bone had merged into the body and the animal seems to have been healthy. Succesful trails have encouraged a group of scientists to try it out on humans too. This only means that for all bone replacements they can be grown from ones own body avoiding speculations of reactions over foreign implants.

An Israeli biotechnology company, Bonus BioGroup that has been working with academics on the technology, will be conducting the first patient trial later this year, the Telegraph reports.

The technology, which has been developed along with researchers at the Technion Institute of Research in Israel, uses three dimensional scans of the damaged bone to build a gel-like scaffold that matches the shape. Stem cells, known as mesenchymal stem cells, which have the capacity to develop into many other types of cell in the body, are obtained from the patient's fat using liposuction. These are then grown into living bone on the scaffold inside a "bioreactor" - an automated machine that provides the right conditions to encourage the cells to develop into bone.

If things go well it would be more easy option to get the bones replaced and the technology is sure to gain momentum with low calcium diets being the order of the day. (With inputs from internet-AarKay)
