Gingival mesenchymal stem cells(GMSCs)are a population of mesenchymal stem cells found in the lamina propria of gingi-val tissue and can be isolated not only from healthy gingival tissue but also from hyperplastic or even inflamed gingival tissue.GMSCs have become a hot topic of research in oral disease treatment because of their abundant sources,easy availability,unique immunomod-ulatory properties and multi-directional differentiation potential.GMSCs have been used in the treatment of periodontitis,gingival reces-sion,oral cancer,mandibular defects,peripheral nerve injury repair and so on.To prevent and treat oral diseases,this study will re-view the recent progress of research on the application of GMSCs in oral diseases.
