Researches may have found a way to grow back a damaged spine.  

Bad discs between vertebrae are a common cause of lower back pain and it was often thought near impossible for the discs, which are cartilage, to heal.  

However, Swedish researchers believe they have been able to grow human stem cells that would help a damaged disc to regenerate.  

Disc degeneration is a change in the properties of invertebrate discs, which are mainly made of cartilage, that leads to the risk of them becoming too thin.

Degenerative discs are thought to be responsible for lower back pain as one vertebrae rubs onto another. Back discs are generally thought to be unable to heal themselves.
