Emory University researchers say that dental pulp stem cells can stimulate growth and generation of several types of neural cells.
Reporting their findings in the journal Stem Cells, the researchers say that dental pulp stem cells show promise for use in cell therapy and regenerative medicine, particularly therapies associated with the central nervous system.
Dr. Anthony Chan, who led the study at the Yerkes National Primate Research Center, revealed that his team placed dental pulp stem cells from the tooth of a rhesus macaque into the hippocampal areas of mice, and they stimulated growth of new neural cells and formed neurons.
Since dental pulp stem cells can be isolated from anyone at any age during a visit to the dentist, Chan is interested in the possibility of dental pulp stem cell banking.
"Being able to use your own stem cells for therapy would greatly decrease the risk of cell rejection that we now experience in transplant medicine," says Chan.
His research team is currently planning to study whether dental pulp stem cells from monkeys with Huntington's disease can enhance brain cell development in the same way those derived from healthy monkeys did in their experiments.
