Differentially expressed long noncoding RNA expression between periodontal ligament stem cells from healthy periodontal tissue and periodontal ligament stem cells from inflammatory periodontal tissue.

Project description:Periodontitis can impair the osteogenic differentiation of human periodontal mesenchymal stem cells, but the underlying molecular mechanisms are still poorly understood. Long noncoding RNAs (lncRNAs) have been demonstrated to play significant roles under both physiologic and pathological conditions. We performed comprehensive lncRNAs profiling by lncRNA microarray to identify differentially expressed long noncoding RNA expression between Periodontal ligament stem cells from healthy Periodontal tissue and periodontal ligament stem cells from inflammatory periodontal tissue. Our analysis identified 233 lncRNAs and 423 mRNAs that were differently expressed (fold change >2.0, p-value < 0.05) between the two groups of cells. The GO analysis revealed that the significantly down-regulated biological processes included multicellular organismal process, developmental process and multicellular organismal development and the significantly up-regulated biological processes included cellular process, biological regulation and response to stimulus in periodontal ligament stem cells from inflammatory periodontal tissue. The Pathway analysis revealed that the differentially expressed mRNAs may involved in Focal adhesion, ECM-receptor interaction, Bacterial invasion of epithelial cells, Long-term depression, Circadian entrainment and HIF-1 signaling pathway. Two-condition experiment, periodontal ligament stem cells from healthy periodontal tissue (hPDLSCs) vs. periodontal ligament stem cells from inflammatory periodontal tissue (pPDLSCs), Biological replicates: 3 control replicates (hPDLSCs), 3 testing replicates (pPDLSCs).

Reverse Transcription quantitative PCR (RT-q PCR) analysis of osteogenic-related markers for osteogenic differentiation from human periodontal ligamen stem cells

Project description:We pre-treated human periodontal ligament stem cells (hPDLSCs) under Iinterleukin-6 (IL-6) in osteogenic inductive medium (OM) on osteogenic differentiation potential and investigate the specific signaling pathway by clarifying with several antagonists (Dkk-1, SP600125, SB431542, and DAPT) and siRNA (siWnt2B, siWnt10B, and siWnt5A) to identify the differences in the expression pattern of osteogenic related markers by reverse transcription quantitative polymerase chain reaction (RT-qPCR).

Cyclic stretch-induced exosomes from periodontal ligament cells promote osteoblasts osteogenic differentiation via the miR-181d-5p/TNF signaling pathway

Project description:Objective: To investigate the effects of stretch-induced periodontal ligament cell (PDLC) exosomes on osteoblast differentiation, and to explore their regulatory role in mechanical force-related periodontal tissue remodeling.Design: After applying 20% stretch loading to human periodontal ligament cells, exosomes were extracted from the supernatant and co-cultured with osteoblasts to detect their effects on osteogenic differentiation. Meanwhile, the exosomes were sequenced by high-throughput microRNA sequencing for bioinformatic analysis and validation to explore exosome signaling pathways through miRNAs.Results: Stretch-induced PDLC exosomes could be taken up by osteoblasts and promoted osteogenic differentiation of osteoblasts, as demonstrated by the increased expression levels of osteogenesis-related factors and enhanced ALP staining. In the miRNA profile of differentially expressed PDLC exosomes under stretch loading, miRNA-181d-5p was up-regulated significantly. The expression levels of osteogenesis-related factors and ALP staining were also increased in osteoblasts transfected with miR-181d-5p, and this effect might be related to the inhibitory role of exosomal miR-181d-5p on tumor necrosis factor (TNF).Conclusions: Stretch-induced PDLC exosomes exhibited a promoting effect on osteogenic differentiation, which might result from the inhibition of TNF via exosomal miR-181d-5p.

Comparative analysis of proteomes and secretomes of human mesenchymal stem cells isolated from six sources during osteogenic differentiation

Project description:Ability to perform osteogenic differentiation is one of the minimal criteria of mesenchymal stem cells (MSCs). Still, it is generally unknown whether osteogenic differentiation is universal cell fate or various phenotypically similar cell states. Besides this, MSCs and their secretomes are actively using for cell/cell-free therapy development, but systemic inter-source variation in MSCs secretomes, proteomes and differentiation mechanisms are still poorly understood. Therefore, here we compared proteomic and secretomic profiles of human mesenchymal cells from six sources: osteoblasts (bone), WJ-MSCs (Warton’s jelly), AD-MSCs (adipose), PDLSCs (tooth: Periodontal Ligament Stem Cells), DPSCs (tooth: Dental Pulp Stem Cells) and GFs (tooth: Gingival Fibroblasts). For experiments we used cells in early passages (3-5) isolated from 3-6 individuals. All cells were compared in standard cultivation and in the 10th day after induction of osteogenic differentiation.

Comprehensive analysis of M2 macrophage-derived exosomes facilitating osteogenic differentiation of human periodontal ligament stem cells

Project description:As the primary seed cells in periodontal tissue engineering, the role of periodontal ligament stem cells (PDLSCs) in periodontal tissue regeneration and bone remodeling during orthodontic tooth movement (OTM) has been well documented. Nevertheless, the impact of different polarization states of macrophages on the osteogenic differentiation of PDLSCs is poorly understood. M0, M1 and M2 macrophage-derived exosomes (M0-exo, M1-exo and M2-exo) were treated with primary cultured human PDLSCs, respectively. Identification of differentially expressed microRNAs (DE-miRNA) in M0-exo and M2-exo by miRNA microarray. In summary, we have indicated for the first time that M2-exo can promote osteogenic differentiation of human PDLSCs, and have revealed the functions and pathways involved in the DE-miRNAs of M0-exo and M2-exo and their downstream targets.
