Purpose: To investigate the role of embelin in periodontal ligament stem cells (PDLSCs) an vitro model periodontitis.Methods: Lipopolysaccharide (LPS)-stimulated PDLSCs was used to construct a periodontitis cell model. treatment group were pretreated with different concentrations Embelin, and CCK-8 TUNEL staining analyze viability apoptosis. Enzyme-linked immunosorbent assay (ELISA) kits evalua...

Previous studies have shown a generalised increase in bone mass in patients with osteoarthritis (OA). Using molecular histomorphometry, this study examined the in vivo expression of mRNA encoding bone anabolic factors and collagen type I genes (COL1A1, COL1A2) in human OA and non-OA bone. Bone samples were obtained from the intertrochanteric (IT) region of the proximal femur, a skeletal site di...

OBJECTIVES The effects of bone morphogenetic protein-2 (BMP-2) and enamel matrix derivative (EMD) respectively with mineral trioxide aggregate (MTA) on hard tissue regeneration have been investigated in previous studies. This study aimed to compare the osteogenic effects of MTA/BMP-2 and MTA/EMD treatment in MC3T3-E1 cells. MATERIALS AND METHODS MC3T3-E1 cells were treated with MTA (ProRoot, ...

Hydrogen sulfide (H2S) is a gas signaling molecule that has multiple influences on physiological and pathological processes in the mammalian body, including vasodilation, neurotransmission, inflammation, hypoxia sensing and bone remodeling. Our previous studies suggested that H2S might be involved in the periodontal tissue remodeling during the orthodontic tooth movement (OTM) via increasing pe...

Linarin (LIN), a flavonoid which exerts both anti-inflammatory and antioxidative effects, has been found to promote osteogenic differentiation. However, the molecular mechanism of its effect on osteoblast differentiation was unclear. In the present study, LIN from Flos Chrysanthemi Indici (FCI) was isolated in order to investigate the underlying mechanisms of LIN on MC3T3-E1 cells (a mouse oste...

This study investigated the effects of altered CXCL12/CXCR4 axis on the bone morphogenetic protein 2 (BMP-2)/Smad/runt-related transcription factor 2 (Runx2)/Osterix (Osx) signal axis and osteogenic gene expression during osteogenic differentiation of mesenchymal stem cells (MSCs), to gain understanding of the link between migration and osteogenic differentiation signal axis and MSCs osteogenic...

BACKGROUND The combination of drugs and exercise was the effective treatment in bone injure and rebuilding in clinic. As mechanical strain has potential in inducing the differentiation of osteoblasts in our previous study, the further research to investigate the combination of mechanical strain and icariin stimulation on inducing osteoblast proliferation, differentiation and the possible mechan...

Abstract Background and Aims Chronic kidney disease (CKD) patients suffering from end-stage renal often undergo dialysis treatment. Haemodialysis (HD) spend most of their time in sedentary behaviour, having therefore poor physical function, as well frequently develop mineral bone disorders due to disease-induced systemic alterations such abnormally high resorption rates exceeding formation. In ...

Composites of bone marrow-derived osteoblasts (BMOs) and porous ceramics have been widely used as a bone graft model for bone tissue engineering. Perfusion culture has potential utility for many cell types in three-dimensional (3D) culture. Our hypothesis was that perfusion of medium would increase the cell viability and biosynthetic activity of BMOs in porous ceramic materials, which would be ...
