The cells featured in the study are gingival mesenchymal stem cells (GMSC), which are found in the gingiva, or gum tissue, within the mouth. GMSC, like other stem cells, have the ability to develop into different types of cells as well as affect the immune system.
“Gingiva is very unique in our body,” says Professor Songtao Shi, the study’s senior author. “It has much less inflammatory reaction and heals much faster when compared to skin.”
Previously, the developmental origins and abilities of GMSC hadn’t been fully illustrated. This study shows that there are two types of GMSC: those that arise from the mesoderm layer of cells during embryonic development (M-GMSC) and those that come from cranial neural crest cells (N-GMSC). The cranial neural crest cells develop into many important structures of the head and face, and 90 percent of the gingival stem cells were found to be N-GMSC.
The study indicates that the stem cells in the gingiva – obtained via a simple biopsy of the gums – may have important medical applications in the future.
“We will further work on dissecting the details of the gingiva stem cells, especially their notable immunoregulatory property,” says first author Xingtian Xu, specialized lab technician at the Ostrow School of Dentistry Center for Craniofacial Molecular Biology.
“Through the study of this unique oral tissue, we want to shed the light on the translational applications for improving skin wound healing and reducing scar formation.”
“Gingivae Contain Neural-crest- and Mesoderm-derived Mesenchymal Stem Cells” appeared online on July 18 in the Journal of Dental Research and was funded by the National Institute of Dental and Craniofacial Research.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
