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.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
