Dental Research: Gingival Stem Cells Can Be Used in Tissue Regeneration

Jul 19, 2013

July 18, 2013 — Gingivae represent a unique soft tissue that serves as a biological barrier to cover the oral cavity side of the maxilla and mandible. Recently, the gingivae were identified as containing mesenchymal stem cells (GMSCs). However, it is unknown whether the GMSCs are derived from cranial neural crest cells (CNCC) or the mesoderm. Today, the International and American Associations for Dental Research (IADR/AADR) published a paper titled “Gingivae Contain Neural-crest- and Mesoderm-derived Mesenchymal Stem Cells.” The paper, written by lead author Songtao Shi, Center for Craniofacial Molecular Biology, Ostrow School of Dentistry, University of Southern California, Los Angeles, USA, is published in the OnlineFirst portion of the IADR/AADR Journal of Dental Research. In this study, Shi and his team of researchers demonstrated that around 90 percent of GMSCs are derived from CNCC and 10 percent from the mesoderm. In comparison with mesoderm MSCs (M-GMSCs), CNCC-derived GMSCs (N-GMSCs) show an elevated capacity to differentiate into neural cells and chondrocytes as well as to modulate immune cells. When transplanted into mice with dextran sulfate sodium-induced colitis, N-GMSCs showed superior effects in ameliorating inflammatory-related disease phenotype in comparison with the M-GMSC treatment group. Further research is required to understand the interaction between the neural crest cell derived and mesoderm derived gingivae mesenchymal stem cells (N-GMSCs and M-GMSCs) in terms of their functional roles in gingival immune defense and wound healing. “The tooth and surrounding tissues are a rich source of stem cells, and this JDR manuscript demonstrates that gingivae contain highly proliferative stem cells from two different embryonic origins and that these cells exhibit distinct behaviors,” said JDR Associate Editor Jacques...

Help Save Lives

Jul 16, 2013

Help Save Lives Did you know that 1 in every 3 people will need blood donation at some point in their lives? I didn’t realise the need  was so high until I heard an interview yesterday with a representative from the Blood Bank. She also said that although 1 in 3 people will need blood only about 1 in 30 people make donations. You don’t need to be a genius to work out there is a serious shortfall.  You also never know when you might need blood. And as this is National Blood Donor Week there has never been a better time to start! So why not join the Lasting Impressions Team in supporting this essential service! Follow the link below to find out more and to read the story of three kids who rely on regular donations of blood just to do the things we take for granted....

Fossil Kangaroo Teeth Reveal Mosaic of Pliocene Ecosystems in Queensland

Jul 12, 2013

 The teeth of a kangaroo and other extinct marsupials reveal that southeastern Queensland 2.5-5-million-years ago was a mosaic of tropical forests, wetlands and grasslands and much less arid than previously thought. The chemical analysis of tooth enamel that suggests this diverse prehistoric habitat is published June 12 in the open access journal PLOS ONE by Shaena Montanari from the American Museum of Natural History and colleagues from other institutions. The carbon isotope ratios present in these fossil teeth revealed that the extinct kangaroo ate plants similar to those consumed by present-day kangaroos in temperate and tropical regions, rather than the plants that now grow in this region. The fossils examined also suggest that different animals in the area occupied specialized dietary niches and did not rely on identical sources of food. As the authors explain, “This period, the Pliocene, is critical to understand the origins and evolution of Australia’s unique modern animals. It is during this time that the Australian fauna first began to take on its modern appearance and distinctiveness, with many modern Australian marsupials, such as the agile wallaby Macropus gracilis, first appearing in Pliocene fossil deposits.” Montanari adds, “It is vital for us to understand what types of environments Australian megafauna thrived in during the Pliocene. Obtaining detailed environmental records from this time can help us find the drivers of the subsequent extinctions of many of these large marsupials.”...

It is less predictable for the deep staining caused by childhood antibiotics Teeth whitening will not work for everyone: that’s why a careful diagnosis by a dentist is required first.
