Gingival tissue-derived mesenchymal stem cells (MSCs) were recently identified and characterized as having multipotential differentiation and immunomodulatory properties in vitro and in vivo, and they represent new postnatal stem cell types for cytotherapy and regenerative medicine. However, the utility of gingival MSCs (GMSCs) as alternatives to(More)
OBJECTIVE To analyze the relationship of genetic polymorphisms in IL1β, IL6, TNF-α genes and their receptors genes with rheumatoid arthritis (RA) for northwest Han Chinese. This study also explores whether there are gene-gene interactions among these genetic polymorphisms. METHODS A total of 452 patients with RA and 373 matched healthy controls were(More)
Multipotent postnatal stem cells can be isolated from human periodontal ligaments (PDLs) and have the potential for large-scale expansion, offering a reliable cell source for clinical use in periodontal regenerative therapies. However, the effects of aging on the mesenchymal stem cell (MSC) properties of these cells remain undefined. The aims of this study(More)
Genipin is obtained from the fruit of Gardenia jasminoides Ellis and acts as an herbal medicine or functional food in East Asia. In addition to produce natural colorant, it possesses widely antiinflammatory, antithrombotic, antidepressive and anticarcinogenic activities. However, little research focuses on the potential of genipin for drug-drug(More)
CONTEXT Paeonia lactiflora Pall. (Ranunculaceae) has been used for more than 1000 years in traditional Chinese medicine for the treatment of gynecological problems, cramp, pain, giddiness, and congestion. Paeoniflorin, monoterpene glycosides isolated from P. lactiflora, possesses a variety of pharmacological activities. However, the pharmacological activity(More)
In situ tissue engineering has been proposed as a promising method to address the need for the clinical regeneration of a wide variety of damaged tissues. This approach comprises the use of a cell-free instructive scaffold that incorporates and releases topical chemotactic factors to recruit host endogenous stem/progenitor cells for tissue regrowth at the(More)
Periodontitis, which progressively destroys tooth-supporting structures, is one of the most widespread infectious diseases and the leading cause of tooth loss in adults. Evidence from preclinical trials and small-scale pilot clinical studies indicates that stem cells derived from periodontal ligament tissues are a promising therapy for the regeneration of(More)
Cell sheet engineering is a scaffold-free delivery concept that has been shown to improve mesenchymal stem cell-mediated regeneration of injured or pathologically damaged periodontal tissues in preclinical studies and several clinical trials. However, the best strategy for cell sheet production remains to be identified. The aim of this study was to(More)
During development of disease, complex intracellular signaling pathways regulate an intricate series of events, including resistance to external toxins, the secretion of cytokines and the production of pathological phenomena. Adenosine 3',5'-cyclic monophosphate (cAMP) is a nucleotide that acts as a key second messenger in numerous signal transduction(More)
Recently, human dental pulp stem cells (DPSCs) isolated from inflamed dental pulp tissue have been demonstrated to retain some of their pluripotency and regenerative potential. However, the effects of periodontal inflammation due to periodontitis and its progression on the properties of DPSCs within periodontally compromised teeth remain unknown. In this(More)
