Abstract
Mesenchymal stem cells (MSCs) have gained substantial attention in regenerative medicine due to their multilineage differentiation potential and immunomodulatory capabilities. MSCs have demonstrated therapeutic promise in numerous preclinical and clinical studies across a variety of diseases, including neurodegenerative disorders, cardiovascular diseases, and autoimmune conditions. Recently, priming MSCs has emerged as a novel strategy to enhance their therapeutic efficacy by preconditioning them for optimal survival and function in challenging in vivo environments. This study presented a comprehensive bibliometric analysis of research activity in the field of priming mesenchymal stem cells (MSCs) from 2003 to 2023. Utilizing a dataset of 585 documents, we explored research trends, leading authors and countries, productive journals, and frequently used keywords. We also explored priming strategies to augment the therapeutic efficacy of MSCs. Our findings show increasing research productivity with a peak in 2019, identified the United States as the leading contributor, and highlighted WANG JA as the most prolific author. The most published journal was Stem Cell Research & Therapy. Keyword analysis revealed core research areas emerging hotspots, while coword and cited sources visualizations elucidated the conceptual framework and key information sources. Further studies are crucial to advance the translation of primed MSCs from bench to bedside, potentially revolutionizing the landscape of regenerative medicine.

Abstract
The jawbone, a unique structure in the human body, undergoes faster remodeling than other bones due to the presence of stem cells and its distinct immune microenvironment. Long-term exposure of jawbones to an oral environment rich in microbes results in a complex immune balance, as shown by the higher proportion of activated macrophage in the jaw. Stem cells derived from the jawbone have a higher propensity to differentiate into osteoblasts than those derived from other bones. The unique immune microenvironment of the jaw also promotes osteogenic differentiation of jaw stem cells. Here, we summarize the various types of stem cells and immune cells involved in jawbone reconstruction. We describe the mechanism relationship between immune cells and stem cells, including through the production of inflammatory bodies, secretion of cytokines, activation of signaling pathways, etc. In addition, we also comb out cellular interaction of immune cells and stem cells within the jaw under jaw development, homeostasis maintenance and pathological conditions. This review aims to eclucidate the uniqueness of jawbone in the context of stem cell within immune microenvironment, hopefully advancing clinical regeneration of the jawbone.

Abstract
Dental pulp stem cells (DPSCs) have received a lot of attention as a regenerative medicine tool with strong immunomodulatory capabilities. The excessive inflammatory response involves a variety of immune cells, cytokines, and has a considerable impact on tissue regeneration. The use of DPSCs for controlling inflammation for the purpose of treating inflammation-related diseases and autoimmune disorders such as supraspinal nerve inflammation, inflammation of the pulmonary airways, systemic lupus erythematosus, and diabetes mellitus is likely to be safer and more regenerative than traditional medicines. The mechanism of the anti-inflammatory and immunomodulatory effects of DPSCs is relatively complex, and it may be that they themselves or some of the substances they secrete regulate a variety of immune cells through inflammatory immune-related signaling pathways. Most of the current studies are still at the laboratory cellular level and animal model level, and it is believed that through the efforts of more researchers, DPSCs/SHED are expected to be transformed into excellent drugs for the clinical treatment of related diseases.

Superior protective effects of PGE2 priming mesenchymal stem cells against LPS-induced acute lung injury (ALI) through macrophage immunomodulation. Stem Cell Res Ther 2023; 14:48.

Abstract
BACKGROUND Mesenchymal stem cells (MSCs) have demonstrated remarkable therapeutic promise for acute lung injury (ALI) and its severe form, acute respiratory distress syndrome (ARDS). MSC secretomes contain various immunoregulatory mediators that modulate both innate and adaptive immune responses. Priming MSCs has been widely considered to boost their therapeutic efficacy for a variety of diseases. Prostaglandin E2 (PGE2) plays a vital role in physiological processes that mediate the regeneration of injured organs. METHODS This work utilized PGE2 to prime MSCs and investigated their therapeutic potential in ALI models. MSCs were obtained from human placental tissue. MSCs were transduced with firefly luciferase (Fluc)/eGFP fusion protein for real-time monitoring of MSC migration. Comprehensive genomic analyses explored the therapeutic effects and molecular mechanisms of PGE2-primed MSCs in LPS-induced ALI models. RESULTS Our results demonstrated that PGE2-MSCs effectively ameliorated lung injury and decreased total cell numbers, neutrophils, macrophages, and protein levels in bronchoalveolar lavage fluid (BALF). Meanwhile, treating ALI mice with PGE2-MSCs dramatically reduced histopathological changes and proinflammatory cytokines while increasing anti-inflammatory cytokines. Furthermore, our findings supported that PGE2 priming improved the therapeutic efficacy of MSCs through M2 macrophage polarization. CONCLUSION PGE2-MSC therapy significantly reduced the severity of LPS-induced ALI in mice by modulating macrophage polarization and cytokine production. This strategy boosts the therapeutic efficacy of MSCs in cell-based ALI therapy.

Abstract
INTRODUCTION Stem cells of the apical papilla (SCAP) play an important role in regenerative endodontic procedures (REPs). Previous studies have shown that during REPs, bacteria can activate the innate immune system and cause indirect stem cell toxicity, leading to the lysis of SCAP. N-acetylcysteine (NAC) treated cells are resistant to apoptosis and have increased differentiation capabilities. The immunomodulatory properties of NAC treated SCAP are still unknown. Hence, the aim of this study is to evaluate the interactions of SCAP pre-treated with and without NAC with the immune system. METHODS Flow cytometric analysis was performed to assess the effects of NAC on SCAP viability. Human SCAP were then cultured and were either pre-treated with NAC or non-treated and co-cultured with human Peripheral blood mononuclear cells (PBMCs). A lactate dehydrogenase assay was performed to evaluate the levels of immune cell mediated apoptosis followed by an enzyme-linked immunosorbent assay (ELISA) to measure levels of pro-inflammatory cytokines for these co-cultures. Data were analyzed using an ANOVA with a post-hoc Tukey test. RESULTS Cells treated with NAC had similar levels of viability as the controls. SCAP pre-treated with NAC had a significantly lower immune cell-mediated cytotoxicity to non-activated and activated PBMCs. The ELISA results showed that SCAP pre-treated with NAC induced lower levels of proinflammatory cytokines. CONCLUSIONS SCAP pre-treated with NAC have a higher chance of surviving the activated immune system. This information may provide a better insight into the properties of these stem cells and may be the key to making REPs more predictable.

Abstract
Mesenchymal stromal cells (MSCs) have attracted intense interest in the field of dental tissue regeneration. Dental tissue is a popular source of MSCs because MSCs can be obtained with minimally invasive procedures. MSCs possess distinct inherent properties of self-renewal, immunomodulation, proangiogenic potential, and multilineage potency, as well as being readily available and easy to culture. However, major issues, including poor engraftment and low survival rates in vivo, remain to be resolved before large-scale application is feasible in clinical treatments. Thus, some recent investigations have sought ways to optimize MSC functions in vitro and in vivo. Currently, priming culture conditions, pretreatment with mechanical and physical stimuli, preconditioning with cytokines and growth factors, and genetic modification of MSCs are considered to be the main strategies; all of which could contribute to improving MSC efficacy in dental regenerative medicine. Research in this field has made tremendous progress and continues to gather interest and stimulate innovation. In this review, we summarize the priming approaches for enhancing the intrinsic biological properties of MSCs such as migration, antiapoptotic effect, proangiogenic potential, and regenerative properties. Challenges in current approaches associated with MSC modification and possible future solutions are also indicated. We aim to outline the present understanding of priming approaches to improve the therapeutic effects of MSCs on dental tissue regeneration.

Abstract
OBJECTIVES Mesenchymal stem cells (MSCs) exist in almost all tissues. Their unique nature is completed by their immunomodulatory functions, holding promise for the treatment of many diseases. An inflammatory environment precedes the immunosuppressive abilities of MSCs and this study was intended to better understand how umbilical cord MSCs (UCMSCs) react to the process of inflammation, regarding their basic characteristics and behavior when primed with the key pro-inflammatory cytokine, Interferon-γ (IFNγ). MATERIALS AND METHODS Human MSCs from the umbilical cord were isolated, expanded, and treated with IFNγ. Primed cells were analyzed to define their ability to form colonies, their morphology, differentiation potential, proliferation, and apoptosis rate. RESULTS UCMSCs treated with IFNγ changed their fibroblast-like morphology and retained the expression of typical MSCs markers. IFNγ treated UCMSCs had significantly higher MFI levels regarding the expression of HLA-I (980.43 ± 556.64) and PD-L1 (598.04 ± 416.90) compared with the control cells (144.97 ± 78.5 and 122.05 ± 103.83, respectively; P<0.01). Under the influence of IFNγ, the cells had a lower population doubling time compared with the control cultures (50.345 ± 9.155 versus 61.135 ± 21.110, respectively; P<0.01) and higher numbers of colony-forming unit-fibroblasts (26.0 ± 12.2 versus 10.2 ± 8.0, respectively; P<0.05). The primed MSCs could not undergo osteogenic and adipogenic differentiation. IFNγ increased the percentage of cells in the apoptotic state on day eight (29.470 ± 6.59 versus 15.708 ± 6.190, respectively; P<0.01). CONCLUSION The properties of UCMSCs can be influenced by the pro-inflammatory cytokine IFNγ.

Abstract
OBJECTIVES Lung cancer is the main cause of cancer death, and its incidence is increasing worldwide. The goal of this study is to evaluate in vitro and in vivo tumor targeting behavior of [99mTc]Tc -HYNIC-(Ser)3-J18 in lung carcinoma (SK-MES-1)-bearing mice. MATERIALS AND METHODS The J18 (RSLWSDFYASASRGP) peptide was conjugated with hydrazinonicotinamide (HYNIC) via three serine amino acids as a linker at the peptide's N-terminal and then labeled with technetium-99m using tricine and tricine/EDDA as the co-ligands. The radiolabeled peptides were assessed for in vitro receptor binding, specific binding, and saturation affinity. In vivo biodistribution studies were also performed for 99mTc-peptide 1 (tricine co-ligand) and 99mTc-peptide 2 (tricine/EDDA coligands) in nude mice bearing SK-MES-1 xenograft tumors. RESULTS In vitro studies showed high specific binding for 99mTc-peptide 1 in SKMES-1 cells compared with 99mTc-peptide 2 (11.5 vs. 4.5). The KD values for 99mTc-peptide 1 and 99mTc-peptide 2 were reported to be 3.1±0.3 nM and 3.46 ± 0.8 nM, respectively. The biodistribution study also showed high significant tumor to muscle ratios of 5.1 and 6.18 for 99mTc-peptide 1 at 1 and 2 hr after injection, respectively, while these ratios were 3.81 and 5.18 for peptide 2, respectively. CONCLUSION Overall, 99mTc-labeled J18 peptide in the presence of tricine as co-ligand has better in vitro and in vivo tumor targeting properties in SK-MES-1 cells than tricine/EDDA co-ligands. These findings show that the 99mTc-labeled J18 peptide is a good candidate for lung carcinoma targeting.

Abstract
Dental pulp stem cells (DPSCs) are important in tooth physiology, contributing to development, repair, regeneration, and immunomodulatory processes. However, their role in inflammatory mechanisms underlying pulpitis is not well understood. We evaluated the influence of DPSCs stimulated with calcitonin gene-related peptide (CGRP), a proinflammatory neuropeptide, on the expression of mediators released from DPSCs and the effect of these mediators on sensory neuron activity. Human DPSCs were treated with either control media or media containing CGRP (10-8 M) for 7 d, and the conditioned media (CM) containing DPSC-released mediators was collected. The expression of cytokines and chemokines from DPSCs was evaluated by reverse transcription quantitative polymerase chain reaction. The effects of the CM from CGRP-primed DPSCs (primed DPSC-CM) were evaluated on sensory afferents by using primary cultures of mouse trigeminal neurons and an organotypic model of cultured human pulp slices. Mouse trigeminal neurons and human pulp explants were pretreated for 24 h with control or primed DPSC-CM and then stimulated with capsaicin. Afferent activity was measured by quantifying the response to capsaicin via live cell calcium imaging in mouse neurons and CGRP released from pulp explants. Gene expression analysis showed that primed DPSCs overexpressed some proinflammatory cytokines and chemokines, including chemokines CXCL1 and CXCL8, which are both agonists of the receptor CXCR2 expressed in sensory neurons. Primed DPSC-CM increased human pulp sensory afferent activity as compared with control DPSC-CM. Similarly, primed DPSC-CM increased the intensity of calcium responses in cultured mouse trigeminal neurons. Furthermore, the CXCR2 antagonist SB225002 prevented trigeminal neuron sensitization to capsaicin induced by primed DPSC-CM. In conclusion, mediators released by DPSCs, primed with the proinflammatory mediator CGRP, induce neuronal sensitization through CXCR2 receptor. These data suggest that DPSCs might contribute to pain symptoms that develop in pulpitis.

Abstract
INTRODUCTION Pulpitis is an inflammation of dental pulp caused by bacterial proliferation near or within pulpal tissues. In advanced stages, when the inflammation is associated with pulp necrosis, pulp preservation is dependent on dental pulp stem cells (DPSCs) that can differentiate into odontoblastlike cells and produce reparative dentin. In this study, we evaluated the influence of sensory neurons through calcitonin gene-related peptide (CGRP) on DPSC viability and proliferation and the ability of DPSCs to differentiate into mineralizing cells. METHODS Commercially available DPSCs were treated with varying doses of CGRP, and metabolic activity, viability, proliferation, and cell death were evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assays, trypan blue staining, 5-bromo-2'-deoxyuridine cell proliferation assay, and caspase-3 staining, respectively. DPSC differentiation was assessed with alizarin red staining and by quantifying messenger RNA expression of odontoblast makers. RESULTS CGRP induced a dose-dependent decrease of DPSC metabolic activity that was prevented by the CGRP receptor antagonist CGRP 8-37. The decrease in the proportion of live cells induced by CGRP is associated with a decrease of cell proliferation but not with caspase-3-dependent apoptosis. Interestingly, dexamethasone-induced DPSC differentiation into mineralizing cells was neither inhibited nor enhanced by CGRP treatment. CONCLUSIONS The neuropeptide CGRP has an inhibitory effect on DPSC proliferation but does not enhance or inhibit the differentiation of DPSCs into mineralizing cells. This suggests that CGRP might negatively influence the ability of DPSCs to contribute to regenerative or tissue repair processes.

Abstract
Human adult mesenchymal stem or stromal cells (h-MSC) therapy has gained considerable attention due to the potential to treat or cure diseases given their immunosuppressive properties and tissue regeneration capabilities. Researchers have explored diverse strategies to promote high h-MSC production without losing functional characteristics or properties. Physical stimulus including stiffness, geometry, and topography, chemical stimulus, like varying the surface chemistry, and biochemical stimuli such as cytokines, hormones, small molecules, and herbal extracts have been studied but have yet to be translated to industrial manufacturing practice. In this review, we describe the role of those stimuli on h-MSC manufacturing, and how these stimuli positively promote h-MSC properties, impacting the cell manufacturing field for cell-based therapies. In addition, we discuss other process considerations such as bioreactor design, good manufacturing practice, and the importance of the cell donor and ethics factors for manufacturing potent h-MSC.

Abstract
Objective To investigate the function of enhancer of zeste homolog 2 (EZH2) in the migration and chemotaxis of human dental tissue-derived mesenchymal stem cells. Methods The expression of EZH2, C-X-C motif chemokine ligand 11 (CXCL11), CXCL16, and CXCR1 in stem cells from the apical papilla (SCAPs) was determined by real-time reverse transcription PCR and western blotting. The effects of EZH2 on the homing of SCAPs and the effects of EZH2-overexpressing SCAP culture supernatant on periodontal ligament stem cells (PDLSCs) were tested by scratch migration assays and transwell chemotaxis assays. Results EZH2 overexpression significantly enhanced the migration and chemotaxis of SCAPs and upregulated the expression of CXCL11, CXCL16, and CXCR1 in SCAPs. EZH2 depletion had the opposite effect, impairing the migration and chemotaxis of SCAPs and downregulating the expression of CXCL11, CXCL16, and CXCR1. The culture supernatant of EZH2-overexpressing SCAPs advanced the migration and chemotaxis of PDLSCs. Conclusions EZH2 evidently promoted the migration and chemotaxis of SCAPs by upregulating the expression of CXCL11, CXCL16, and CXCR1. Moreover, EZH2-overexpressing SCAPs enhanced the homing, migration, and chemotaxis of PDLSCs via paracrine signaling.

Abstract
INTRODUCTION Dental stem cells have gained importance recently and are being used for various purposes in regenerative medicine and dentistry. Although much research has been done to show the various properties of these dental stem cells, the immunomodulatory properties of some of these stem cells are still unknown. This is important considering these cells are being used routinely. Therefore, the aim of this study was to investigate the interactions between the activated immune cells and 3 types of dental-derived mesenchymal stem cells: dental pulp stem cells, stem cells from human exfoliated deciduous teeth, and stem cells of the apical papilla (SCAP). METHODS SCAP, dental pulp stem cells, stem cells from human exfoliated deciduous teeth, and periodontal ligament fibroblasts were cultured, and various assays were performed including a proliferation assay, flow cytometric analysis, lactate dehydrogenase and chromium-51 cytotoxicity assays, and an enzyme-linked immunosorbent assay to evaluate the interactions of these dental stem cells when cocultured with either peripheral blood mononuclear cells or natural killer cells. RESULTS SCAP were less resistant to immune cell-mediated cytotoxicity as seen from the results obtained from the LDH and chromium-51 cytotoxicity assays. The flow cytometric analysis showed a lower resilience of SCAP to cytotoxic compounds. The enzyme-linked immunosorbent assay results demonstrated that the SCAP induced high levels of proinflammatory cytokine secretion compared with the other dental stem cells. CONCLUSIONS SCAP did not perform as well as the other dental stem cells. This could in turn affect their survival and differentiation abilities as well as their functionality. This may be an important aspect to consider when selecting dental stem cells for various regenerative procedures.

Abstract
OBJECTIVES This study investigated the in vitro cytotoxicity as well as the proinflammatory cytokine expression of provisional resin materials on primary cultured human dental pulp stem cells (hDPSCs). METHODS Five commercially available provisional resin materials were chosen (SNAP [SN], Luxatemp [LT], Jet [JE], Revotek LC [RL], and Vipi block [VB]). Eluates that were either polymerizing or already set were added to hDPSCs under serially diluted conditions divided into three different setting times (25% set, 50% set, and 100% set) and incubated for 24 hours with 2× concentrated culture media. Cell cytotoxicity tests were performed by LDH assay and live and dead confocal microscope images. The expression of proinflammatory cytokines in SN and VB was measured using cytokine antibody arrays. Data were analyzed using repeated measures analysis of variance (ANOVA) or ANOVA followed by the Tukey post hoc test at a significance level of p<0.05. RESULTS Cytotoxicity greater than 30% was observed in the 50% diluted culture in SN, LT, and JE in the already set stage (p<0.05), while it was detected in SN and LT in early or intermediate stage samples. The cytotoxicity of SN, JE, and LT was greater with eluates from the polymerizing phase compared to that from already set samples (p<0.05), as observed by live and dead images. On the other hand, RL and VB did not exhibit cytotoxicity greater than 30%. Proinflammatory cytokines were not detected in 12.5% diluted culture with eluates from VB and early set stage SN. CONCLUSIONS The eluates from chemical-activated provisional resin materials during polymerization (SN, LT, and JE) were cytotoxic to hDPSCs and may adversely affect pulp tissue.

EZH2 regulates dental pulp inflammation by direct effect on inflammatory factors. Arch Oral Biol 2017; 85:16-22.

Abstract
OBJECTIVE Pulpitis is a multi-factorial disease that could be caused by complex interactions between genetics, epigenetics and environmental factors. We aimed to evaluate the role of Enhancer of Zeste Homolog 2 (EZH2) in the inflammatory response of human dental pulp cells (HDPCs) and dental pulp tissues. METHODS The expressions of inflammatory cytokines in HDPCs treated by EZH2 complex or EZH2 siRNA with or without rhTNF-α were examined by quantitative real-time polymerase chain reaction (q-PCR). The levels of secreted inflammatory cytokines including IL-6, IL-8, IL-15, CCL2 and CXCL12 in culture supernatants were measured by Luminex assay. In rat pulpitis model, the effects of EZH2 on dental pulp tissues were verified by histology. We invested the mechanisms of the effect of EZH2 on the inflammatory factors by ChIP assay. RESULTS EZH2 down-regulation inhibited the expression of inflammatory factors, including IL-6, IL-8, IL-15, CCL2 and CXCL12 in HDPCs. EZH2 complex promoted the expression and secretion of these inflammatory factors in HDPCs, while EZH2 silencing could attenuate the promotion of inflammatory factors that were induced by rhTNF-α. In pulpitis models of rats, EZH2 down-regulation inhibited the inflammatory process of dental pulp while EZH2 complex showed no significant facilitation of pulpal inflammation. In addition, EZH2 could bind on the promoters of IL-6, IL-8 and CCL2, but not IL-15 and CXCL12, to affect the transcription of these proinflammatory cytokines. CONCLUSIONS In HDPCs, EZH2 could induce inflammation, while EZH2 down-regulation could attenuate the inflammatory responses. EZH2 plays an important role in this inflammatory process of dental pulp.

Abstract
Studies in recent years have established that the principal effects in cardiac cell therapy are associated with paracrine/autocrine factors. We combined several complementary techniques to define human cardiac progenitor cell (CPC) secretome constituted by 914 proteins/genes; 51% of these are associated with the exosomal compartment. To define the set of proteins specifically or highly differentially secreted by CPC, we compared human mesenchymal stem cells and dermal fibroblasts; the study defined a group of growth factors, cytokines and chemokines expressed at high to medium levels by CPC. Among them, IL-1, GROa (CXCL1), CXCL6 (GCP2) and IL-8 are examples whose expression was confirmed by most techniques used. ELISA showed that CXCL6 is significantly overexpressed in CPC conditioned medium (CM) (18- to 26-fold) and western blot confirmed expression of its receptors CXCR1 and CXCR2. Addition of anti-CXCL6 completely abolished migration in CPC-CM compared with anti-CXCR2, which promoted partial inhibition, and anti-CXCR1, which was inefficient. Anti-CXCL6 also significantly inhibited CPC CM angiogenic activity. In vivo evaluation also supported a relevant role for angiogenesis. Altogether, these results suggest a notable angiogenic potential in CPC-CM and identify CXCL6 as an important paracrine factor for CPC that signals mainly through CXCR2.

Abstract
During caries, dental pulp expresses a range of pro-inflammatory cytokines in response to the infectious challenge. Interferon gamma (IFN-γ) is a dimerized soluble cytokine, which is critical for immune responses. Previous study has demonstrated that IFN-γ at relative high concentration (100 ng/mL) treatment improved the impaired dentinogenic and immunosuppressive regulatory functions of disease-derived dental pulp stem cells (DPSCs). However, little is known about the regulatory effects of IFN-γ at relative low concentration on healthy DPSC behavior (including proliferation, migration, and multiple-potential differentiation). Here we demonstrate that IFN-γ at relatively low concentrations (0.5 ng/mL) promoted the proliferation and migration of DPSCs, but abrogated odonto/osteogenic differentiation. Additionally, we identified that NF-κB and MAPK signaling pathways are both involved in the process of IFN-γ-regulated odonto/osteogenic differentiation of DPSCs. DPSCs treated with IFN-γ and supplemented with pyrrolidine dithiocarbamate (PDTC, an NF-κB inhibitor) or SB203580 (a MAPK inhibitor) showed significantly improved potential for odonto/osteogenic differentiation of DPSCs both in vivo and in vitro. These data provide important insight into the regulatory effects of IFN-γ on the biological behavior of DPSCs and indicate a promising therapeutic strategy for dentin/pulp tissue engineering in future endodontic treatment.

Pooled Human Serum Increases Regenerative Potential of In Vitro Expanded Stem Cells from Human Extracted Deciduous Teeth. ADVANCES IN EXPERIMENTAL MEDICINE AND BIOLOGY 2017; 1083:29-44.

Abstract
In regenerative therapy, in vitro expansion of stem cells is critical to obtain a significantly higher number of cells for successful engraftment after transplantation. However, stem cells lose its regenerative potential and enter senescence during in vitro expansion. In this study, the influence of foetal bovine serum (FBS) and pooled human serum (pHS) on the proliferation, morphology and migration of stem cells from human extracted deciduous teeth (SHED) was compared. SHED (n = 3) was expanded in KnockOut DMEM supplemented with either pHS (pHS-SM) or FBS (FBS-SM). pHS was prepared using peripheral blood serum of six healthy male adults, aged between 21 and 35 years old. The number of live SHED was significantly higher, from passage 5 to 7, when cultured in pHS-SM compared to those cultured in FBS-SM (p < 0.05). Number of cells having flattened morphology, characteristics of partially differentiated and senescent cells, was significantly lower (p < 0.05) in pHS-SM (3%) compared to those in FBS-SM (7%). Furthermore, migration of SHED in pHS-SM was found to be more directional. The presence of selected ten paracrine factors known for their proliferation and migration potential was detected in all six individual human sera, used to produce pHS, none of which were detected in FBS. Ingenuity Pathway Analysis showed the possible involvement of the 'ephrin receptor signalling pathway' to regulate the proliferation and migration of SHED in pHS-SM. In conclusion, pHS-SM showed significantly higher proliferation rate and could maintain significantly lower number of senescent cells and support directional migration of cells.

[PMID: 26768693 PMCID: PMC11108394 DOI: 10.1007/s00018-015-2126-5] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2015] [Revised: 12/16/2015] [Accepted: 12/22/2015] [Indexed: 12/15/2022]
Abstract
Dental stem cells are an emerging star on a stage that is already quite populated. Recently, there has been a lot of hype concerning these cells in dental therapies, especially in regenerative endodontics. It is fitting that most research is concentrated on dental regeneration, although other uses for these cells need to be explored in more detail. Being a true mesenchymal stem cell, their capacities could also prove beneficial in areas outside their natural environment. One such field is the central nervous system, and in particular, repairing the injured spinal cord. One of the most formidable challenges in regenerative medicine is to restore function to the injured spinal cord, and as yet, a cure for paralysis remains to be discovered. A variety of approaches have already been tested, with graft-based strategies utilising cells harbouring appropriate properties for neural regeneration showing encouraging results. Here we present a review focusing on properties of dental stem cells that endorse their use in regenerative medicine, with particular emphasis on repairing the damaged spinal cord.
