Abstract
Osteonecrosis of the femoral head (ONFH) is a common refractory orthopedic disease, which is one of the common causes of hip pain and dysfunction. ONFH has a very high disability rate, which is associated with a heavy burden to patients, families, and society. The pathogenesis of ONFH is not completely clear. At present, it is believed that it mainly includes coagulation dysfunction, abnormal lipid metabolism, an imbalance of osteogenic/adipogenic differentiation, and poor vascularization repair. The prevention and treatment of ONFH has always been a great challenge for clinical orthopedic surgeons. However, recent studies have emphasized that the use of mesenchymal stem cells (MSCs) to treat steroid-induced ONFH (SONFH) is a promising therapy. This review focuses on the role and molecular mechanism of epigenetic regulation in the progress of MSCs in the treatment of SONFH, and discusses the significance of the latest research in the treatment of SONFH from the perspective of epigenetics.

The influence of inflammation on the characteristics of adipose-derived mesenchymal stem cells (ADMSCs) and tissue repair capability in a hepatic injury mouse model. Stem Cell Res Ther 2023; 14:334. [PMID: 37981679 PMCID: PMC10659042 DOI: 10.1186/s13287-023-03532-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 10/10/2023] [Indexed: 11/21/2023] Open
Abstract
BACKGROUND Mesenchymal stem cells (MSCs) are adult stem cells with self-renewal and multi-directional differentiation potential and possess the functions of immunomodulation, regulation of cell growth, and repair of damage. Over recent years, MSCs have been found to regulate the secretion of inflammatory factors and to exert regulatory effects on various lymphocytes in inflammatory states, and on the subsequent repair of tissue damage caused by inflammation. In the present study, we analyzed the effects of tissue inflammation on the characteristics of MSCs. METHODS Human fat derived from the infrapatellar fat pad (IPFP) of knees with differing degrees of inflammation was extracted from specimens derived from total knee arthroplasties. HE and immunohistochemical staining was performed to directly observe the evidence and degree of inflammation in human infrapatellar fat pad tissue in order to classify MSCs cells, by their origin, into highly inflamed and lowly inflamed groups, and to study the effect of tissue inflammation on cell acquisition rates via cellular counting data. Flow cytometry assays were performed to investigate the effect of tissue inflammation on MSC surface marker expression. Trilineage differentiation, including osteogenesis, adipogenesis, and chondrogenesis, was performed to assess the effect of tissue inflammation on the ability of MSCs to undergo directed differentiation. The effect of tissue inflammation on the ability of MSCs to proliferate was investigated via clone formation studies. RNA-sequencing was performed to evaluate the transcriptomes of MSCs derived from different areas of inflammation. The effect of tissue inflammation on tissue repair capacity and safety of MSCs was investigated via a murine model of acute liver injury. RESULTS The results of cell count data indicate that a high degree of tissue inflammation significantly decreases the acquisition rate of MSCs, and the proportion of CD34+ and CD146+ cells. The results of our trilineage differentiation assay show that a higher degree of inflammation decreases osteogenic differentiation and enhances adipogenic and chondrogenic differentiation of MSCs. However, these differences were not statistically significant. Clone formation assays indicate that the degree of tissue inflammation at the MSC source does not significantly affect the proliferative capacity of MSCs. The transcriptomes of MSCs remain relatively stable in fat pad tissues derived from both highly and lowly inflamed samples. The results of acute liver injury investigations in mice indicate that MSCs of high and low inflammatory tissue origin have no significant difference in their tissue repair capability. CONCLUSIONS High tissue inflammation at the source of MSCs reduces the acquisition rate of MSCs and the percentage of CD34+ and CD146+ cells acquisition. However, source tissue inflammation may not significantly affect trilineage differentiation potential and proliferative capacity of MSCs. Also, MSCs obtained from differing source degrees of inflammation retain stable and similar transcriptomic profile and are both safe and efficacious for tissue repair/regeneration without detectable differences.

Abstract
Cardiac calcification is a crucial but underrecognized pathological process, greatly increasing the risk of cardiovascular diseases. Little is known about how cardiac fibroblasts, as a central mediator, facilitate abnormal mineralization. Erythropoietin-producing hepatoma interactor B2 (EphrinB2), previously identified as an angiogenic regulator, is involved in fibroblast activation, while its role in the osteogenic differentiation of cardiac fibroblasts is unknown. Bioinformatics analysis was conducted to characterize the expression of the Ephrin family in human calcified aortic valves and calcific mouse hearts. The effects of EphrinB2 on cardiac fibroblasts to adopt osteogenic fate was determined by gain- and loss-of-function. EphrinB2 mRNA level was downregulated in calcified aortic valves and mouse hearts. Knockdown of EphrinB2 attenuated mineral deposits in adult cardiac fibroblasts, whereas overexpression of EphrinB2 promoted their osteogenic differentiation. RNA sequencing data implied that Ca2+-related S100/receptor for advanced glycation end products (RAGE) signaling may mediate EphrinB2-induced mineralization in cardiac fibroblasts. Moreover, L-type calcium channel blockers inhibited osteogenic differentiation of cardiac fibroblasts, implying a critical role in Ca2+ influx. In conclusion, our data illustrated an unrecognized role of EphrinB2, which functions as a novel osteogenic regulator in the heart through Ca2+ signaling and could be a potential therapeutic target in cardiovascular calcification.NEW & NOTEWORTHY In this study, we observed that adult cardiac fibroblasts but not neonatal cardiac fibroblasts exhibit the ability of osteogenic differentiation. EphrinB2 promoted osteogenic differentiation of cardiac fibroblasts through activating Ca2+-related S100/RAGE signaling. Inhibition of Ca2+ influx using L-type calcium channel blockers inhibited EphrinB2-mediated calcification of cardiac fibroblasts. Our data implied an unrecognized role of EphrinB2 in regulating cardiac calcification though Ca2+-related signaling, suggesting a potential therapeutic target of cardiovascular calcification.

Abstract
BACKGROUND Tumor necrosis factor-alpha (TNF-α) is one of the crucial inflammatory factors in alveolar bone metabolism during the process of periodontitis. Autophagy is indispensable for proper osteoblast function. However, the effects of autophagy on osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) in inflammatory microenvironment and the underlying mechanisms remain to be clarified. The aim of the present study was to investigate whether autophagy participates in hPDLSCs differentiation after treated with TNF-α and explore the underlying mechanisms. METHODS AND RESULTS Characterizations of hPDLSCs were evaluated by Alizarin-red S staining, Oil red staining and flow cytometry. hPDLSCs were treated with various concentrations of TNF-α. Rapamycin or 3MA was used to achieve or inhibit autophagy activation. AKT signaling was inhibited using ARQ092. Cell proliferation was evaluated using Cell Counting Kit-8 (CCK8) assay. Real-time reverse transcriptase-polymerase chain reaction assay (RT-PCR), western blot, alkaline phosphatase (ALP) staining and Alizarin Red S staining were applied to evaluate levels of osteogenic differentiation and autophagy. CCK8 showed that low concentrations of TNF-α had no influence on cell proliferation, while high concentrations of TNF-α inhibited proliferation. Low concentrations of TNF-α promoted osteogenic differentiation and autophagy, while high concentrations of TNF-α inhibited osteogenic differentiation and autophagy in hPDLSCs. The levels of osteogenic differentiation in hPDLSCs were partly effected after co-incubation with 0.1 ng/mL TNF-α with 3MA or Rapamycin. ARQ092 enhanced 0.1 ng/mL TNF-α-induced ALP expression and mineral nodule formation. CONCLUSION Low concentrations of TNF-α promote hPDLSCs osteogenic differentiation by activation of autophagy via inhibition of AKT/mTOR signaling.

Abstract
Bone fracture healing is a complex process involving various signaling pathways. It remains an unsolved issue the fast and optimal management of complex or multiple fractures in the field of orthopedics and rehabilitation. Bone fracture healing is largely a four-stage process, including initial hematoma formation, intramembrane ossification, chondrogenesis, and endochondral ossification followed by further bone remodeling. Many studies have reported the involvement of immune cells and cytokines in fracture healing. On the other hand, the Tumor Necrosis Factor (TNF) family and TNF receptor superfamily (TNFRSF) play a pivotal role in many physiological processes. The functions of the TNF family and TNFRSF in immune processes, tissue homeostasis, and cell differentiation have been extensively studied by many groups, and treatments targeting specific TNFRSF members are in progress. In terms of bone fracture management, it has been discovered that several members of TNFRSF have very distinct functions in different stages of fracture healing, including TNFR1, TNFR2, and receptor activator of nuclear factor kappa-B (RANK) pathways. More specifically, TNFR1 is associated with osteoclastogenesis and TNFR2 is associated with osteogenic differentiation, while RANK is in association with bone remodeling. In this review, we will discuss and summarize the involvement of members of TNFRSF including TNFR1, TNFR2, and Receptor activator of nuclear factor kappa-B (RANK) pathways in different stages of fracture healing and bone remodeling and the current treatment trend involving TNFRSF agonists and antagonists.

Cell Signal 2022; 96:110376. [PMID: 35690294 DOI: 10.1016/j.cellsig.2022.110376] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 05/31/2022] [Accepted: 06/03/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND Osteoporosis is a degenerative skeletal disease essentially caused by bone remodeling disorder. EphrinB2-EphB4 signaling play critical regulatory roles in bone remodeling via communication between osteoclasts and osteoblasts. Eldecalcitol (ED-71), a new vitamin D analog, is a high-potential drug for treating osteoporosis; however, its mechanism has yet to be determined. This study aims to investigate whether EphrinB2-EphB4 signal mediates the process of osteoporosis improved by ED-71. MATERIALS AND METHODS An ovariectomized (OVX) rat model was constructed in vivo. ED-71 at 30 ng/kg was orally administered once daily for 8 weeks. Osteoclast activity and EphrinB2-EphB4 expression were evaluated by hematoxylin and eosin staining, tartrate-resistant acid phosphatase (TRAP) staining, and immunohistochemical staining. The mRNA levels of oxidation stress factors in the bone tissue were tested by reverse transcription polymerase chain reaction (RT-PCR). An H2O2-stimulated model in vitro was established to simulate the status of osteoporosis. Osteoclastogenesis and associated protein were detected by TRAP staining, F-actin ring formation assay, PCR, and Western blot analysis. EprhrinB2 and EphB4 levels were determined by immunofluorescence, PCR, and Western blot analysis. EprhrinB2 small-interfering RNA knocked down the EprhrinB2 in osteoclasts, and an EphB4 antibody blocked EphB4 in osteoblasts. RESULTS ED-71 prevented bone loss and decreased the number of osteoclasts in vivo relative to the OVX group. In addition, the bone tissue of OVX rat displayed as an increased level of oxidation stress, which could be inhibited by ED-71. In vitro, in the simulation of osteoporosis with H2O2, ED-71 reversed the increase H2O2-induced oxidative stress. ED-71 then inhibited osteoclastogenesis and osteoclast function, accompanied by increased EphrinB2 expression in osteoclasts. Notably, EphrinB2 knockdown reversed the inhibitory effect of ED-71 on osteoclasts. ED-71 also enhanced EphB4 expression in osteoblasts in vivo and in vitro. Further research showed that ED-71 inhibited osteoclastogenesis in co-culture systems, which was weakened by blocking EphB4 in osteoblasts. CONCLUSIONS ED-71 inhibited osteoclastogenesis by enhancing EphrinB2-EphB4 signaling between osteoclasts and osteoblasts, preventing osteoporosis. This theory explains the role of ED-71 in the treatment of osteoporosis.

Abstract
Inflammation and alveolar bone destruction constitute the main pathological process of periodontitis. However, the molecular mechanisms of bone destruction under the inflammation environment remain unclear. This study aims to explore the role of Ephrin-B2/EphB4 signaling in osteogenic differentiation under the inflammation environment. Mouse pre-osteoblasts MC3T3-E1 were pretreated with lipopolysaccharide of Porphyromonas gingivalis (Pg-LPS). The Ephrin-B2/EphB4 signaling was activated, and the osteogenic differentiation of cells was examined. The results showed that activation of Ephrin-B2/EphB4 signaling promoted the expression levels of osteogenic differentiation-related genes, and also relieved the inhibitory effect of Pg-LPS on osteogenesis. Noticeably, the effect of Ephrin-B2/EphB4 signaling might be related to the mitogen-activated protein kinase (MAPK) pathway. While applying Ephrin-B2-Fc and EphB4-Fc to periodontitis mice, we observed the reduction of alveolar crest destruction. The current study revealed the possible role of Ephrin-B2/EphB4 signaling in reducing bone destruction in periodontitis and suggested its potential values for further research.

Abstract
Elucidation of the underlying mechanisms governing osteogenic differentiation is of significant importance to the improvement of therapeutics for bone-related inflammatory diseases. Tumor necrosis factor-α (TNF-α) is regarded as one of the major agents during osteogenic differentiation in an inflammatory environment. miR-335-5p post-transcriptionally downregulates the Dickkopf WNT signaling pathway inhibitor 1 (DKK1) protein level by specifically binding to the DKK1 3′UTR and activating Wnt signaling. The role of miR-335-5p in TNF-α-induced post-transcriptional regulation of DKK1 remains to be elucidated. In the present study, the mRNA and protein levels of DKK1 and the level of miR-335-5p were determined in MC3T3-E1 cells and the primary calvarial osteoblasts treated with or without TNF-α. The role of NF-κB signaling in TNF-α-induced post-transcriptional regulation of DKK1 was also evaluated. The present study determined that although TNF-α treatment exhibited cell-specific effects on DKK1 mRNA expression, the stimulation of TNF-α time- and concentration-dependently upregulated the protein levels of DKK1. In primary calvarial osteoblasts, the decreased miR-335-5p level induced by TNF-α-activated NF-κB signaling served an important role in mediating the post-transcriptional regulation of DKK1 by TNF-α treatment. In MC3T3-E1 cells, the post-transcriptional regulation of DKK1 by TNF-α treatment was more complicated and involved other molecular signaling pathways in addition to the NF-κB signaling. In conclusion, TNF-α treatment served an important role in the post-transcriptional regulation of DKK1 expression, which requires further investigation. The results of the present study not only provided new insights into the regulatory effects of miR-335-5p on osteogenic differentiation in an inflammatory microenvironment, but may also promote the development of potential therapeutic strategies for the treatment of bone-related inflammatory diseases.

BMC Mol Cell Biol 2020; 21:29. [PMID: 32299362 PMCID: PMC7164363 DOI: 10.1186/s12860-020-00273-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Accepted: 04/03/2020] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Low concentrations of tumor necrosis factor-alpha (TNF-α) and its receptor TNFR2 are both reported to promote osteogenic differentiation of osteoblast precursor cells. Moreover, low concentrations of TNF-α up-regulate the expression of EphB4. However, the molecular mechanisms underlying TNF-α-induced osteogenic differentiation and the roles of TNFR2 and EphB4 have not been fully elucidated. RESULTS The ALP activity, as well as the mRNA and protein levels of RUNX2, BSP, EphB4 and TNFR2, was significantly elevated in MC3T3-E1 murine osteoblast precursor cells when stimulated with 0.5 ng/ml TNF-α. After TNFR2 was inhibited by gene knockdown with lentivirus-mediated shRNA interference or by a neutralizing antibody against TNFR2, the pro-osteogenic effect of TNF-α was partly reversed, while the up-regulation of EphB4 by TNF-α remained unchanged. With EphB4 forward signaling suppressed by a potent inhibitor of EphB4 auto-phosphorylation, NVP-BHG712, TNF-α-enhanced expressions of TNFR2, BSP and Runx2 were significantly decreased. Further investigation into the signaling pathways revealed that TNF-α significantly increased levels of p-JNK, p-ERK and p-p38. However, only the p-ERK level was significantly inhibited in TNFR2-knockdown cells. In addition, the ERK pathway inhibitor, U0126 (10 μM), significantly reversed the positive effect of TNF-α on the protein levels of RUNX2 and BSP. CONCLUSIONS The EphB4, TNFR2 and ERK/MAPK signaling pathway comprises a signaling axis to mediate the positive effect of TNF-α on osteogenic differentiation.

Abstract
Erythropoietin-producing hepatomocellular receptors and their receptor-interacting proteins (Eph/ephrin) can participate in the regulation of growth and development and promote the development of diseases through short-distance signal transduction between cells. To study the mechanism of Eph/ephrin and oral-related diseases, we provided a new theoretical basis and a strategy for the treatment of oral diseases. The Eph/ephrin pathway has been used to regulate oral diseases, especially in periodontal disease prevention, orthodontic bone reconstruction, and biological treatment of oral tumors. This paper reviews the research progress of Eph/ephrin pathway in oral-related diseases.

Int J Mol Med 2020; 45:897-909. [PMID: 31985015 PMCID: PMC7015143 DOI: 10.3892/ijmm.2020.4473] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Accepted: 12/23/2019] [Indexed: 12/28/2022] Open
Abstract
The aim of the present study was to evaluate the effect of ephrinB2 gene-transfected canine periodontal ligament stem cells (cPDLSCs) on the regulation of osteogenic differentiation. cPDLSCs were transfected with a transgenic null-control green fluorescent protein (GFP) vector (termed Vector-cPDLSCs) or with NFNB2 GFP-Blasticidin (termed EfnB2-cPDLSCs). Subsequently, the osteogenic differentiation of Vector-cPDLSCs and EfnB2-cPDLSCs was assessed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR), alkaline phosphatase (ALP) assay and Alizarin Red S staining. The migratory abilities of cPDLSCs, Vector-cPDLSCs and EfnB2-cPDLSCs were also assessed. Following osteogenic induction of Vector-cPDLSCs and EfnB2-cPDLSCs, the protein expression levels of collagen I, Runt-related transcription factor 2, osteocalcin, ephrin type-B receptor 4 (EphB4), phospho-EphB4, ephrinB2 and phosphoephrinB2 were analyzed by western blot assays. Following gene transfection, the RT-qPCR and western blotting results revealed that the mRNA and protein expression levels of ephrinB2, respectively, were significantly increased in EfnB2-cPDLSCs compared with that in Vector-cPDLSCs (P<0.05). ALP and Alizarin Red S staining assays revealed increased ALP activity and mineralization nodules, respectively, in EfnB2-cPDLSCs. Cell proliferation and migration assays revealed that EfnB2-cPDLSCs exhibited enhanced proliferation and migration compared with Vector-cPDLSCs (P<0.05). In conclusion, the findings of the current study indicated that ephrinB2 gene-modified cPDLSCs exhibited enhanced osteogenic differentiation, with the ephrinB2 reverse signaling and EphB4 forward signaling pathways serving a key role in this process. Furthermore, ephrinB2 gene modification was observed to promote the migration and proliferation of cPDLSCs.

Dose Response 2020; 18:1559325819901239. [PMID: 32009856 PMCID: PMC6974759 DOI: 10.1177/1559325819901239] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2019] [Revised: 12/10/2019] [Accepted: 12/19/2019] [Indexed: 12/12/2022] Open
Abstract
Objective: To explore the role of microRNA (miR-21) in new bone formation in ankylosing
spondylitis (AS) as mediated by different concentration of tumor necrosis
factor-α (TNF-α). Methods: Fibroblasts isolated from the hips of patients with AS were induced to
osteogenesis. These cells were then stimulated with varying concentrations
of TNF-α. MicroRNA-21 expressions were evaluated using reverse
transcription–polymerase chain reaction (RT-PCR) and osteogenesis was
detected via Alizarin Red S (ARS) staining and measurement of alkaline
phosphatase (ALP) activity. Relative expressions of p-STAT3, Nuclear STAT3,
cytoplasm STAT3, Runx2, BMP2, osteopontin, osteocalcin, and LC3B in AS
fibroblasts were measured after exposure to different concentrations of
TNF-α. The STAT3-inhibiting small interfering RNA allowed further
exploration on its impact on miR-21 and primary miR-21 expressions. A
proteoglycan-induced arthritis (PGIA) Balb/c mouse model was established in
order to monitor sacroiliac joint (SIJ) inflammation and subsequent damage
through magnetic resonance image. Serum miR-21 and TNF-α expressions were
evaluated using RT-PCR and enzyme-linked immunosorbent assay. At week 16,
mice models were transfected intravenously with miR-21 overexpressing agomir
and miR-21 inhibiting antagomir for 7 successive days. The rate of abnormal
bone formation at SIJ was evaluated using microcomputed tomography and
hematoxylin and eosin staining at week 24. Western blot analysis enabled
quantification of STAT-3, JAK-2, and interleukin (IL)-17A expressions
present in the SIJ. Results: The in vitro miR-21 expression and osteogenesis activity were noted to be
augmented in the setting of low TNF-α concentrations (0.01-0.1 ng/mL) while
they were depressed in settings with higher TNF-α concentrations (1-10
ng/mL). Samples with the most distinct ARS manifestation and ALP activity as
well as the highest miR-21 expressions were those who received 0.1 ng/mL of
TNF-α. Primary miR-21 was found to be notable raised by Si-STAT3, while the
converse effect was seen in mature miR-21 expressions. Intravenous injection
of exogenous miR-21 contributed to new bone formation and significantly
elevated expressions of STAT3, JAK2, and IL-17 in PGIA mice. Conclusions: The results revealed that miR-21 may act as a potential mediator between new
bone formation and inflammation in AS.

Abstract
This paper examines the effect of electromagnetic waves, with maxima in the green or red regions of the spectrum, on the morphofunctional state of multipotent mesenchymal stromal cells. The illumination regimes used in our experiments did not lead to any substantial heating of the samples; the physical parameters of the lighting were carefully monitored. When the samples were illuminated with a green light, no significant photostimulatory effect was observed. Red light, on the other hand, had an evident photostimulatory effect. It is shown that photostimulation with a red light decreases the enzymatic activities of mitochondrial dehydrogenases and enhances the viability of cells, their proliferative activity, and their ability to form bone tissue. It is also established that red light stimulates cell proliferation, while not activating the genes that increase the risk of the subsequent malignant transformation of cells or their death. This paper discusses the possible role of hydrogen peroxide in the processes examined.

Stem Cell Res Ther 2019; 10:5. [PMID: 30606261 PMCID: PMC6318982 DOI: 10.1186/s13287-018-1112-x] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2018] [Revised: 12/05/2018] [Accepted: 12/17/2018] [Indexed: 02/07/2023] Open
Abstract
Background The etiology and pathology osteonecrosis of the femoral head (ONFH) are not completely clarified. As a cytokine participating in systemic inflammation, tumor necrosis factor alpha (TNFα) has been shown to be involved in the pathogenesis of ONFH. However, the role of TNFα in ONFH is not clearly clarified. In the present study, we investigated the effects of TNFα on proliferation, angiogenesis, and osteogenic differentiation of rat bone mesenchymal stem cells (rMSCs) and the underlying mechanisms. Methods All femoral bone tissues were separated in surgeries. After extracting total RNA and protein, we evaluated TNFα content by ELISA and the relative expression levels of genes by quantitative real-time PCR and western blot. Also, immunohistochemistry staining was performed to observe the expression of Runx2 in the bone samples. Chick embryo chorioallantoic membrane (CAM) assay was performed to observe the effect of TNFα on angiogenesis. The genomic DNAs were treated by bisulfite modification, and methylation status of CpG sites in the CpG islands of human and rat Runx2 gene promoter was determined by DNA sequencing. The binding of H3K4me3 and H3K27me3 in Runx2 promoter was checked by ChIP assay. RNA-seq analysis was used to find out the genes and pathways changed by TNFα in rMSCs. Results The results demonstrate TNFα promotes cell proliferation and angiogenesis whereas inhibits osteogenesis. Epigenetic regulations including DNA methylation and histone modifications play important roles in mediating the effect of TNFα on osteogenic differentiation. We find an increased rate of CpG methylation in rat Runx2 promoter in TNFα-treated rMSCs, as well as significantly increased occupancy of H3K27me3 in Runx2 gene promoter. The content of TNFα in necrotic tissue is much lower than that of normal tissue. And relevantly, human Runx2 promoter is demethylated in necrotic tissue using bone samples from patient with ONFH. In addition, we have observed that Wnt signaling pathway is inhibited by TNFα as multiple Wnts are markedly decreased in TNFα-treated rMSCs by RNA-seq analysis. Conclusion Taken together, our study shows that TNFα plays complicated roles in the pathogenesis of ONFH, including proliferation, angiogenesis, and osteogenesis. Targeting TNFα should not be considered as an applicable strategy to inhibit the progression of ONFH.

Abstract
Periodontitis has been advocated as a systematic chronic low-grade infection burden. However, the relationship between periodontitis and bone defect healing has not been elucidated. One hundred and eight male Wister rats were randomly assigned into three groups: control (healthy) group, periodontitis group, and periodontitis plus human tumor necrosis factor receptorII:IgG Fc fusion protein (rhTNFR:Fc) group. The experimental periodontitis model was established by ligaturing with orthodontic wire and silk suture plus local administration of 20 μl of lipopolysaccharide (LPS). Mandibular bone defects in size of 4 × 2 × 1 mm were created for all the rats and rhTNFR:Fc subcutaneously injected at neck at a dose of 2.5 mg/kg every 3 days for the periodontitis plus rhTNFR:Fc group. The gene and protein expressions of bone-related markers in the healing tissue were monitored and new bone formation was histologically evaluated. Tartrate-resistant acid phosphatase (TRAP) staining was performed to determine the number of osteoclasts. The results showed that the mRNA and protein expressions of osteogenesis-related markers were significantly lower while nuclear factor of activated T cells, cytoplasmic 1 (NFATc1) gene expression was significantly higher in the periodontitis group. The periodontitis group showed decreased new bone formation and increased number of osteoclasts when compared to the control group. However, there was no significant difference between the periodontitis plus rhTNFR:Fc group and the control group. These results demonstrated that periodontitis may restrain the mandibular bone healing via disturbing osteogenic and osteoclastic balance in which tumor necrosis factor-α (TNF-α) could act as a leverage.

Abstract
Background The osteo-immunomodulatory properties of biomaterials play an important role in the outcomes of bone regeneration. Graphene oxide (GO) has been widely applied in many research fields due to its unique properties. However, the immunomodulatory properties of GO as a biomaterial for bone tissue engineering are still unclear. Materials and methods In this study, we evaluated the Inflammatory response of RAW264.7 cells influenced by GO. Then the osteogenic differentiation of BMSCs, and angiogenic differentiation of human umbilical vein endothelial cells (HUVECs) by stimulation with GO/RAW 264.7-conditioned culture medium were accessed. We also further investi gated the possible mechanisms underlying the osteo- and angio-immunomodulatory effects of GO. Results Our results showed that GO stimulates the secretion of oncostatin M, tumor necrosis factor alpha and other factors through the nuclear factor-κB pathway. GO/RAW264.7-conditioned medium promoted the osteogenic differentiation of BMSCs, stimulated upregulation of the HUVECs of vascular-related receptors, and promoted their tube formation in vitro. Conclusion In conclusion, our research shows that GO, as a biomaterial, can induce the formation of a beneficial osteo-immunomodulatory environment and is a promising biomaterial for bone tissue engineering.

Adv Healthc Mater 2018; 7:e1800361.

Abstract
Bioactive glass (BG) can repair bone defects, however, it is not clear whether BG has the ability for bone augmentation without making any bone defect. Unlike the intramembranous osteogenesis in bone defect repair, the extramembranous osteogenesis occurs outside the cortical bone and the osteoprogenitor cells show the reversed migration. Herein, nanoscale bioactive glass scaffolds (BGSs) are fabricated, and their role and immunomodulation-related mechanism in the extramembranous osteogenesis are investigated. The in vitro migration and differentiation of calvaria preosteoblasts are studied by culturing with peripheral macrophage-conditioned medium after stimulating with BGSs. The results indicate that the proinflammatory environment significantly promotes preosteoblast migration, but has limited effect on osteogenic differentiation. However, the anti-inflammatory environment and BGSs significantly increase the osteogenic differentiation of preosteoblasts. The in vivo extramembranous osteogenesis evaluation shows that the active osteogenesis is observed near the skull. The osteoblasts derived from the reverse migration of cranial cells can be confirmed by comparing with the scaffolds implanted in back subcutaneous which is just colonized by fibrous tissue. This study may bring a fresh perspective for BG in bone regeneration and explore the osteogenic immunomodulation of peripheral macrophages in a nonosteogenic environment.

Int J Mol Med 2018; 42:2031-2041. [PMID: 30015911 PMCID: PMC6108887 DOI: 10.3892/ijmm.2018.3780] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Accepted: 07/06/2018] [Indexed: 11/25/2022] Open
Abstract
The present study investigated the role of bidirectional ephrin-B2/erythropoietin-producing human hepatocellular receptor 4 (ephB4) signaling in the regulation of wear particle-mediated osteoclastogenesis in vitro. Mouse bone marrow macrophages (BMMs) were induced into osteoclasts by receptor activator of nuclear factor-κB ligand (RANKL, 50 ng/ml). EphB4-Fc, an osteoblast membrane surface receptor (4 µg/ml), was used to stimulate the ephrin-B2 ligand of osteoclasts in the presence and absence of titanium (Ti). Tartrate-resistant acid phosphatase (TRAP) staining was used to detect the number of osteoclasts, and phalloidin staining was used to examine the cytoskeletons of the osteoclasts. A bone pit absorption experiment was used to measure osteoclast function. Reverse transcription quantitative polymerase chain reaction and western blot analysis were used to examine osteoclastogenesis. ELISAs were used to detect the production of inflammatory factors. The data demonstrated that Ti significantly promoted the differentiation of BMMs into mature osteoclasts in the presence of RANKL and significantly promoted expression of the ephrin-B2, nuclear factor of activated T-cells 1 (NFATc1), TRAP, Fos proto-oncogene, AP-1 transcription factor subunit (C-FOS), and matrix metalloproteinase 9 (MMP9) genes. Phalloidin and TRAP staining revealed that following the addition of ephB4-Fc, the number, size and cytoskeletal elements of Key words: osteoclasts, osteoblasts, remodeling, ephrin-B2, osteoclastogenesis osteoclasts were significantly decreased compared with those in the titanium particle group without ephB4-Fc. Compared with the titanium particle group, the bone pit absorption experiment revealed significantly decreased absorption pit areas in the titanium particle+ephB4-Fc group. The expression of the NFATc1, TRAP, C-FOS and MMP9 genes was markedly decreased in the ephB4-Fc group; however, the expression of the ephrin-B2 gene was increased compared with the Ti particle group without ephB4-Fc after 5 days. Production of inflammatory cytokines was inhibited by Ti particles through bidirectional signals. Addition of ephB4-Fc inhibited the osteoclast-mediated formation of Ti particles via bidirectional ephrin-B2/ephB4 signaling. Activation of this bidirectional signaling pathway may be a potential clinical treatment for osteolysis surrounding prostheses.

Tumor necrosis factor-alpha inhibits osteogenic differentiation of pre-osteoblasts by downregulation of EphB4 signaling via activated nuclear factor-kappaB signaling pathway. J Periodontal Res 2017; 53:66-72. [PMID: 28857167 DOI: 10.1111/jre.12488] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/01/2017] [Indexed: 12/22/2022]
Abstract
BACKGROUND AND OBJECTIVE The majority of experiments show that tumor necrosis factor-alpha (TNF-α) inhibits osteogenic differentiation of mesenchymal stem cells and pre-osteoblasts by activated nuclear factor-kappaB (NF-κB) signaling. However, the underlying mechanisms by which NF-κB signaling inhibits osteogenic differentiation are not fully understood. The aim of the present study was to investigate whether EphB4 signaling inhibition mediates the effects of TNF-α-activated NF-κB signaling on osteogenic differentiation of pre-osteoblasts. MATERIAL AND METHODS Murine MC3T3-E1 pre-osteoblasts were treated with 10 ng/mL of TNF-α. NF-κB inhibitor, pyrrolidine dithiocarbamate, was used to achieve NF-κB signaling inhibition. EphB4 signaling was activated using ephrinB2-fc. The mRNA expressions of runt related transcription factor 2 (Runx2), bone sialoprotein (BSP) and EphB4 were determined using reverse transcription-polymerase chain reaction. The protein levels of Runx2, BSP, Col Ia1, osteopontin, EphB4, p-NF-κB p65 and NF-κB p65 were evaluated using western blot assays. Alkaline phosphatase (ALP) activity in MC3T3-E1 cells was evaluated by ALP activity kit, and mineral nodule formation was evaluated by Alizarin Red S staining. RESULTS TNF-α inhibited EphB4 expression, while it suppressed Runx2, BSP expression from gene and protein levels as well as ALP activity and mineral nodule formation in MC3T3-E1 cells. Activation of EphB4 signaling by ephrinB2-fc promoted osteogenic differentiation of MC3T3-E1 cells, whereas TNF-α impaired the osteogenic differentiation enhanced by ephrinB2-fc. Pyrrolidine dithiocarbamate blocked the activation of NF-κB signaling induced by TNF-α, while it prevented the downregulation of Runx2, BSP and EphB4, induced by TNF-α. CONCLUSION TNF-α inhibits osteogenic differentiation of pre-osteoblasts by downregulation of EphB4 signaling via activated NF-κB signaling pathway.
