'growing from gum stem cells. Bio Teeth'

Posted by Unknown Tuesday, March 12, 2013 0 comments

Scientists have taken a step closer to growing human teeth from scratch using cells taken from a patient's mouth. They envisage now missing or diseased teeth one day Could Be Replaced by freshly grown, living substitutes.

A "hybrid" tooth made ​​from a mixture of human and mouse embryonic cells gum cells have been grown in laboratory mice to test for That method might be adapted in the future to become an alternative to dental implants.

Researchers believe growing bio-engineered teeth from a patient's own cells Could revolutionize dentistry, Which in recent years has focused on Replacing damaged or missing teeth with porcelain crowns attached to metal implants inserted into the jaw.

"The notion is to Identify cells you can put together and will grow into an immature tooth, Which Will Develop into a mature tooth after it is inserted into the patient's mouth," said Professor Paul Sharpe of King's College London. The "bio-tooth" gum produced by mixing human cells with mouse embryonic cells feasible Formed roots with good periodontal ligaments - the tissue fibers anchoring teeth to the jawbone, I added.

As well as anchoring teeth, the periodontal ligaments act as shock absorbers During chewing. Metal implants are fixed to the bone and do not have shock absorbers, Which can damage the jawbone over time, I said. The study, published in the Journal of Dental Research, is the first demonstration of a tooth grown using human and mouse cells. - The Independent
