Evaluation of the inflammatory and osteogenic response induced by metal particles released during implantoplasty of dental implants

Project description:During implantoplasty there is a large release of metal particles that might induce a pro-inflammatory response and reduce the viability of osteogenic cells, which may compromise the results of dental implants The analysis of the inflammatory response in macrophage cell culture (THP-1) was carried out by RT-qPCR. CCR7, TNF-α and IL-1β genes were analyzed as proinflammatory markers, while CD206, TGF-β and IL-10 were analyzed as antiinflammatory markers. The osteogenic response was studied with human bone marrow mesenchymal stem cells (BM-MSCs). We analyzed Runx2, alkaline phosphatase (ALP) and osteocalcin (OC) genes.

CHD7 regulates osteogenic differentiation of human dental follicle cells via PTH1R signaling

Project description:Chromodomain helicase DNA-binding protein 7 (CHD7) is an ATP-dependent chromatin remodeling enzyme, functioning as chromatin reader to conduct epigenetic modification. Its effect on osteogenic differentiation of human dental follicle cells (hDFCs) remains unclear. Here we show CHD7 expression increases with osteogenic differentiation. knockdown of CHD7 impairs the osteogenic ability of hDFCs, characterized by reduced alkaline phosphatase activity and mineralization, and decreased expression of osteogenesis-related genes. Conversely, CHD7 overexpression enhances the osteogenic differentiation of hDFCs. Mechanically, RNA-seq analyses revealed the down-regulated enrichment of PTH (parathyroid hormone)/PTH1R (parathyroid hormone receptor-1) signaling pathway after CHD7 knockdown. We found the expression of PTH1R positively correlates with CHD7. Importantly, overexpression of PTH1R in CHD7-knockdown hDFCs partially rescued the impaired osteogenic differentiation. Our research demonstrates that CHD7 regulates the osteogenic differentiation of hDFCs by regulating the transcription of PTH1R.

Construction of autonomous osteogenic microtissues based on human dental pulp derived mesenchymal stem cells

Project description:Bone regeneration is currently a major clinical challenge. Adult human mesenchymal stem cells (MSCs) possess a unique advantage in organ tissue repair and physiological function recovery. Human dental pulp derived MSCs (hDPSCs) have the dual advantages of proliferation and osteogenic differentiation abilities. They can be induced to secrete bone matrix proteins to form osteogenic microtissues by constructing an appropriate osteogenic three-dimensional microenvironment. The biological characteristics of hDPSCs from microtissues and two-dimensional cultured cells are compared using RNA sequencing. According to RNA sequencing and subsequent functional verification, the osteogenic activations of hDPSCs might be related to cell adhesion related signaling pathways. In this process, cells could sense the tension from the environment to activate related signaling pathways, such as the FAK/RhoA/Rock signaling pathway. Further, the downstream osteogenic transcription factors could be activited into the nucleus, thereby promoting the expression of osteogenic proteins.

Different osteogenic differentiation behavior of canine mesenchymal stem cells derived from bone marrow and dental pulp: the proteomics profile

Project description:Although various sources of cMSCs show similar characteristics, they are different in osteogenic potential due to their original cellular sources. Thus, this study was designed to globally explore and analyze the in vitro differentiation potential and behavior of canine bone-marrow derived mesenchymal stem cells (cBM-MSCs) and canine dental pulp stem cells (cDPSCs) toward osteogenic lineage. Global study of an in vitro osteogenic differentiation potential of the isolated cells was performed using proteomic-based analysis through mass spectrometry with dimethyl labelling method at day 7 and 14 post-induction, comparing with undifferentiated cells. The obtained results could be used as a comprehensive data and principal knowledge of the osteogenic differentiation potential of cBM-MSCs and cDPSCs in vitro and the trend of MSC-based tissue engineering for osteogenic regenerative therapy, concentrating on cMSCs application.

Role of MSX1 in Osteogenic Differentiation of Dental Pulp Cells

Project description:Msh homeobox 1 (MSX1) is a transcriptional factor regulating embryonic development of limbs and craniofacial tissues including bone and teeth. The purpose of this study was to investigate contribution of MSX1 to the osteogenic potential and calcification-related phenotypic expression of dental pulp stromal/mesenchymal cells isolated from human teeth. Immunohistochemisitry of a 3 week-old mouse molar showed that MSX1 protein was localized to odontoblasts and pulpal mesenchymal cells at different levels and in different manners depending upon the position of the cells in pulp tissue. When dental pulp stromal/mesenchymal cells were exposed to osteogenesis-induction medium, runt-related transcription factor-2 (RUNX2), bone morphogenetic protein-2 (BMP2), alkaline phosphatase (ALPL) and osteocalcin (OCN) mRNA levels, as well as alkaline phosphatase activity, increased on days 4-12, and, thereafter, the matrix was calcified on day 14. However, knockdown of MSX1 with small interfering RNA abolished this induction of the osteoblast-related gene expression, alkaline phosphatase activity and calcification. Interestingly, DNA microarray and quantative PCR analyses revealed that the MSX1 knockdown induced the sterol regulatory element-binding protein 2 (SREBP2) transcriptional factor and its downstream target genes in cholesterol-synthesis pathway. Inhibition of cholesterol synthesis enhances osteoblast differentiation of various mesenchymal cells. Thus, MSX1 may down-regulate the cholesterol synthesis-related genes to ensure osteoblast differentiation of dental pulp stromal/mesenchymal cells.

Extracellular matrix derived from dental pulp stem cells promotes osteogenic differentiation of gingival fibroblasts via Wnt and Hippo signaling pathway

Project description:This study investigated the efficacy of decellularized ECM derived from human dental pulp stem cells (dECM_DPSCs) and gingival-derived mesenchymal stem cells (dECM_GSCs) as an inductive scaffold for osteogenic differentiation of GSCs. ECM was constructed from DPSCs and GSCs that were cultured in a growth medium supplemented with L-ascorbic acid (N-ECM) or osteogenic induction medium (OM-ECM). The gene expression profile was examined using a high-throughput RNA sequencing technique.
