Our Former Faces

February 24, 2013

To put a human face on our ancestors, scientists from the Senckenberg Research Institute used sophisticated methods to form 27 model heads based on tiny bone fragments, teeth and skulls collected from across the globe. The heads are on display for the first time together at the Senckenberg Natural History Museum in Frankfurt, Germany. Continue HERE

Cloning teeth for implantation using stem cells

May 11, 2012

Polymer scaffolds guide stem cells growth into customized sizes and shapes.

LOS ANGELES (KABC): Dentures are the past, dental implants are the present — could the future be teeth grown from stem cells?

“People really care about their teeth and they really care once those teeth are gone,” said Dr. Peter Murray, endodontics professor at Nova Southeastern University. Danka Premovic agrees. When previous dental work failed, she began wearing a mask. “I’m a perky person. I’m a people person and for me to cover up my mouth and wear a mask, it’s just not me,” said Premovic.

Premovic now has eight implants. It’s patients like her that dental regeneration researcher Dr. Murray wants to help. “It would be nice to give people back their own teeth and make their whole body whole again,” said Murray.

To grow teeth, researchers isolate stem cells from the mouth or bone marrow. The cells are multiplied in the lab, then grown on 3-dimensional scaffolds. Stem cells are then attached to an actual tooth. “All the animal studies that have been done so far are very encouraging, so it looks like the clinical trials will be successful,” said Murray.

The teeth can be grown in the lab and implanted in the patient or they could actually grow inside the patient’s mouth, filling in empty spaces with new teeth in just a few months.
