Researchers grow human cartilage from stem cells Updated: 2014-06-02 18:53:49 KST

Researchers grow human cartilage from stem cells
And finally researchers at Columbia University have successfully grown human cartilage for the first time in medical history.
Paul, how did they achieve this scientific breakthrough?

Well, the scientists used stem cells from adult bone marrow and condensed them through a process that mimics how the human body produces fully functional cartilage.
And if proven safe to use on patients, it could potentially revolutionize modern medicine.
According to the research team, cartilage is a simple but important tissue.
It is the only tissue in the body that does not have blood vessels or nerves but it doesn't have the ability to heal over time.
Scientists say this method will eventually be able to help people regrow parts of their body including the jaw, knees and fingers.
But the research team cautioned that this was just the first step.

"This is the kind of technology that should, in principle, make it possible to regenerate any piece of bone interfaced with cartilage in the body. So, we do have technology. We do understand underlying principles. But we are not ready to go into patients. There is a lot of pre-clinical work that will need to be done to make this happen."

The Columbia University team based in New York says they next plan to test the long-term effects of the stem cell grown cartilage to see how the tissue holds up over time.
The study was published in the online journal of "Proceedings of the National Academy of Sciences." Chery.

Alright Paul. Thanks for that update. We'll see you back in just about two hours.
