Stem cells harvested from mice have been used to reattach molars in rats
Researchers from the University of Illinois at Chicago have successfully used stem cells to reattach molars to tooth sockets within lab rats’ mouths. The stem cells were obtained from the periodontal ligament of molars extracted from mice, expanded in an incubator, and then seeded onto barren rat molars. This could have great implications for humans who lose teeth due to gum disease in the future... and for all those toothless old rats out there.
