Up to 2,000 of our 21,000 genes could affect our bone strength, research has found.
In an experiment with mice, researchers attempted to disable each gene and found nine genes that appeared to strengthen or weaken the bone.
These genes had not previously been described and this suggests that approximately 8-10% of our genes are involved in regulating our skeleton.
The result indicate that blocking some of the nine genes could result in higher bone mass and stronger bones.
Researchers are hoping to create antibodies to these genes to test their results.
