Abstract
The management and reconstruction of critical-sized segmental bone defects remain a major clinical challenge for orthopaedic clinicians and surgeons. In particular, regenerative medicine approaches that involve incorporating stem cells within tissue engineering scaffolds have great promise for fracture management. This narrative review focuses on the primary components of bone tissue engineering-stem cells, scaffolds, the microenvironment, and vascularisation-addressing current advances and translational and regulatory challenges in the current landscape of stem cell therapy for critical-sized bone defects. To comprehensively explore this research area and offer insights for future treatment options in orthopaedic surgery, we have examined the latest developments and advancements in bone tissue engineering, focusing on those of clinical relevance in recent years. Finally, we present a forward-looking perspective on using stem cells in bone tissue engineering for critical-sized segmental bone defects.

In Vivo 2023; 37:2564-2576. [PMID: 37905631 PMCID: PMC10621445 DOI: 10.21873/invivo.13364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 07/29/2023] [Accepted: 09/01/2023] [Indexed: 11/02/2023]
Abstract
BACKGROUND/AIM Human dental pulp mesenchymal stem cells (hDPSCs) are considered to be a good cell source for cell-based clinical therapy, due to the advantages of high proliferation capacity, multilineage differentiation potential, immune regulation abilities, less ethnic concerns and non-invasive access. However, hDPSCs were traditionally isolated and expanded in medium containing fetal bovine serum (FBS), which is a barrier for clinical application due to the safety issues (virus transmission and allergy). Although many studies make efforts to screen out a suitable culture medium, the results are not promising so far. Therefore, a standard good manufacturing practice (GMP) compliant culture system is urgently required for the large-scale cell production. This study aimed to find suitable culture conditions for producing clinical grade hDPSCs to meet the requirements for clinical cell-based therapy and further to promote the application of hDPSCs into tissue regeneration or disease cure. MATERIALS AND METHODS We derived hDPSCs from nine orthodontic teeth expanded in two different media: a GMP compliant and xenogeneic serum-free medium (AMMS) and a serum containing medium (SCM). Cell propterties including morphology, proliferation, marker expression, differentiation, stemness, senescence and cytokine secretion between these two media were systematically compared. RESULTS hDPSCs cultured in both media exhibited the typical characteristics of mesenchymal stem cells (MSCs). However, we found that more cell colonies formed in the primary culture in AMMS, and the hDPSCs displayed higher proliferation capacity, differentiation potential and better stemness maintenance during sub-culturing in AMMS. CONCLUSION Cell properties of hDPSCs could be improved when they were isolated and expanded in AMMS, which might provide a good candidate of culture medium for large-scale cell manufacturing.

Abstract
Stem cell-based therapies remain at the forefront of tissue engineering and regenerative medicine because stem cells are a unique cell source with enormous potential to treat incurable diseases and even extend lifespans. The search for the best stem cell candidates continues to evolve and in recent years, dental stem cells have received significant attention due to their easy accessibility, high plasticity, and multipotential properties. Dental stem cells have been the subject of extensive research in both animal models and human clinical trials over the past two decades, and have demonstrated significant potential in ocular therapy, bone tissue engineering, and, of course, therapeutic applications in dentistry such as regenerative endodontics and periodontal tissue regeneration. These new sources of cells may be advantageous for cellular therapy and the advancement of regenerative medicine strategies, such as allogeneic transplantation or therapy with extracellular vesicles (EVs), which are functional nanoscale membrane vesicles produced by cells. This chapter discusses the accumulating research findings on cell-based regenerative therapy utilizing dental stem cells and their derived EVs, which could be a viable tool for the treatment of a variety of diseases and hence extremely valuable to mankind in the long run.

Abstract
Xerostomia is the phenomenon of dry mouth and is mostly caused by hypofunction of the salivary glands. This hypofunction can be caused by tumors, head and neck irradiation, hormonal changes, inflammation or autoimmune disease such as Sjögren's syndrome. It is associated with a tremendous decrease in health-related quality of life due to impairment of articulation, ingestion and oral immune defenses. Current treatment concepts mainly consist of saliva substitutes and parasympathomimetic drugs, but the outcome of these therapies is deficient. Regenerative medicine is a promising approach for the treatment of compromised tissue. For this purpose, stem cells can be utilized due to their ability to differentiate into various cell types. Dental pulp stem cells are adult stem cells that can be easily harvested from extracted teeth. They can form tissues of all three germ layers and are therefore becoming more and more popular for tissue engineering. Another potential benefit of these cells is their immunomodulatory effect. They suppress proinflammatory pathways of lymphocytes and could therefore probably be used for the treatment of chronic inflammation and autoimmune disease. These attributes make dental pulp stem cells an interesting tool for the regeneration of salivary glands and the treatment of xerostomia. Nevertheless, clinical studies are still missing. This review will highlight the current strategies for using dental pulp stem cells in the regeneration of salivary gland tissue.

Abstract
IntroductionThe lifelong eruption places a great demand on the dental pulp and periodontal ligament (PDL) of horse teeth. Cells within the pulp and PDL seem to play a key role during this remodeling.MethodsIn this study, we isolated and cultivated MSCs (medicinal signaling cells) from dental pulp, PDL and retrobulbar fat of four horses. Subsequently, we analyzed them by flow cytometry and immunohistochemistry to determine and compare their characteristics. In addition, we localized these cells within the tissue structure via immunohistochemistry of histological sections. For these analyses, several surface markers were applied.ResultsThe described method illustrates a feasible approach to isolate and cultivate MSCs from equine dental pulp and PDL. In the flow cytometry a vast majority of cultivated cells were positive for CD90 and CD40 and negative for CD11a/18, CD45, CD105 and MHCII suggesting that these cells feature characteristics of MSCs. Immunohistochemistry of histological pulp and PDL sections showed the localization of CD90 positive cells especially in the perivascular region and the subodontoblastic layer.DiscussionOur findings indicate that the isolation and cultivation of MSCs from equine dental pulp and PDL is feasible although an elaborate and complicated harvesting protocol is required. MSCs isolated from dental pulp and PDL are regarded as candidates for new therapeutical approaches in equine dental medicine like regeneration of periodontal lesions, enhancement of periodontal re-attachment after dental replantation and stimulation of pulp-obliteration and apexification in combination with endodontic therapies.

Abstract
OBJECTIVE Stem cells from human exfoliated deciduous teeth (SHED) have bone regeneration ability and potential therapeutic applications. CD146, a cell adhesion protein expressed by vascular endothelial cells, is involved in osteoblastic differentiation of stem cells. The effect of CD146 on SHED-mediated bone regeneration in vivo remains unknown. We aimed to establish efficient conditions for SHED transplantation. MATERIALS AND METHODS SHED were isolated from the pulp of an extracted deciduous tooth and cultured; CD146-positive (CD146+ ) and CD146-negative (CD146- ) populations were sorted. Heterogeneous populations of SHED and CD146+ and CD146- cells were transplanted into bone defects generated in the skulls of immunodeficient mice. Micro-computed tomography was performed immediately and 4 and 8 weeks later. Histological and immunohistochemical assessments were performed 8 weeks later. RESULTS Bone regeneration was observed upon transplantation with CD146+ and heterogeneous populations of SHED, with significantly higher bone regeneration observed with CD146+ cells. Bone regeneration was higher in the CD146- group than in the control group, but significantly lower than that in the other transplant groups at 4 and 8 weeks. Histological and immunohistochemical assessments revealed that CD146+ cells promoted bone regeneration and angiogenesis. CONCLUSION Transplantation of CD146+ SHED into bone defects may be useful for bone regeneration.

Abstract
Regenerative therapy for tissues by mesenchymal stem cell (MSCs) transplantation has received much attention. The cluster of differentiation (CD)146 marker, a surface-antigen of stem cells, is crucial for angiogenic and osseous differentiation abilities. Bone regeneration is accelerated by the transplantation of CD146-positive deciduous dental pulp-derived mesenchymal stem cells contained in stem cells from human exfoliated deciduous teeth (SHED) into a living donor. However, the role of CD146 in SHED remains unclear. This study aimed to compare the effects of CD146 on cell proliferative and substrate metabolic abilities in a population of SHED. SHED was isolated from deciduous teeth, and flow cytometry was used to analyze the expression of MSCs markers. Cell sorting was performed to recover the CD146-positive cell population (CD146+) and CD146-negative cell population (CD146-). CD146 + SHED without cell sorting and CD146-SHED were examined and compared among three groups. To investigate the effect of CD146 on cell proliferation ability, an analysis of cell proliferation ability was performed using BrdU assay and MTS assay. The bone differentiation ability was evaluated using an alkaline phosphatase (ALP) stain after inducing bone differentiation, and the quality of ALP protein expressed was examined. We also performed Alizarin red staining and evaluated the calcified deposits. The gene expression of ALP, bone morphogenetic protein-2 (BMP-2), and osteocalcin (OCN) was analyzed using a real-time polymerase chain reaction. There was no significant difference in cell proliferation among the three groups. The expression of ALP stain, Alizarin red stain, ALP, BMP-2, and OCN was the highest in the CD146+ group. CD146 + SHED had higher osteogenic differentiation potential compared with SHED and CD146-SHED. CD146 contained in SHED may be a valuable population of cells for bone regeneration therapy.

Abstract
INTRODUCTION Dental pulp stem cells (DPSCs) have high proliferative and multilineage differentiation potential in mesenchymal stem cells. However, several studies have indicated that there are individual differences in the potential for osteogenic differentiation of DPSCs, and the factors determining these differences are unknown. OBJECTIVE To identify the genes responsible for the individual differences in the osteogenic differentiation ability of DPSCs. METHODS We divided DPSCs into high and low osteogenic differentiation ability groups (HG or LG) with ALP and von Kossa stain, and compared the gene expression patterns using RNA-seq. In addition, genes that may affect osteogenic differentiation were knocked down using small interfering RNA (siRNA) and their effects were investigated. RESULTS The RNA-seq patterns revealed that VCAM1 and GFPT2 were significantly expressed at higher levels in the HG than in the LG. The results of siRNA analysis showed that VCAM1 and GFPT2 knockdown significantly reduced the expression of osteogenic markers. Furthermore, we analyzed the involvement of these two genes in cell signaling in DPSC differentiation. The results indicated that the VCAM1-mediated Ras-MEK-Erk and PI3K/Akt pathways are involved in the osteogenic differentiation of DPSCs, and that GFPT2-mediated HBP signaling influences the osteogenic differentiation of DPSCs. CONCLUSIONS These findings indicate that DPSCs that highly express VCAM1 and GFPT2 have a high capacity for osteogenic differentiation. Evaluation of VCAM1 and GFPT2 expression in undifferentiated DPSCs may predict the outcome of bone regenerative therapy using DPSCs. Moreover, the expression levels of VCAM1 and GFPT2 in DPSCs may be useful in setting criteria for selecting donors for allogeneic cell transplantation for bone regeneration.

Abstract
Maintaining dental pulp vitality and preventing tooth loss are two challenges in endodontic treatment. A tooth lacking a viable pulp loses its defense mechanism and regenerative ability, making it more vulnerable to severe damage and eventually necessitating extraction. The tissue engineering approach has drawn attention as an alternative therapy as it can regenerate dentin-pulp complex structures and functions. Stem cells or progenitor cells, extracellular matrix, and signaling molecules are triad components of this approach. Stem cells from human exfoliated deciduous teeth (SHED) are a promising, noninvasive source of stem cells for tissue regeneration. Not only can SHEDs regenerate dentin-pulp tissues (comprised of fibroblasts, odontoblasts, endothelial cells, and nerve cells), but SHEDs also possess immunomodulatory and immunosuppressive properties. The collagen matrix is a material of choice to provide structural and microenvironmental support for SHED-to-dentin pulp tissue differentiation. Growth factors regulate cell proliferation, migration, and differentiation into specific phenotypes via signal-transduction pathways. This review provides current concepts and applications of the tissue engineering approach, especially SHEDs, in endodontic treatment.

Abstract
INTRODUCTION The aim of this review is to provide a narrative review on the determinants of dental pulp stem cell (DPSC) heterogeneity that may affect the regenerative properties of these cells. METHODS PubMed, Scopus and Medline (Ovid) literature searches were done on human dental pulp stem cell (hDPSC) heterogeneity. The focus was on human dental pulp stem cells (hDPSCs) with a primary focus on DPSC heterogeneity. RESULTS DPSCs display significant heterogeneity as illustrated by the various subpopulations reported, including differences in proliferation and differentiation capabilities and the impact of various intrinsic and extrinsic factors. CONCLUSIONS The lack of consistent and reliable results in the clinical setting may be due to the heterogeneous nature of DPSC populations. Standardization in isolation techniques and in criteria to characterize DPSCs should lead to less variability in results reported and improve comparison of findings between studies. Single-cell RNA sequencing holds promise in elucidating DPSC heterogeneity and may contribute to the establishment of standardized techniques.

Abstract
The aim of the present study was to evaluate the proliferation rate and the expression of stem cells markers during expansion in primary culture of dental pulp stem cells (DPSCs), comparing different techniques (explant and enzymatic digestion), subject ages (up to 40 and over 40) and cell passages (#2, #5 and #8). DPSCs were isolated using either the enzymatic digestion (ED) or explant (EX) technique. The number of days needed for the cells to reach confluence was determined. Immunophenotyping was performed by immunofluorescence and flow cytometry analysis using antibodies specific for nestin, vimentin, CD44, CD146, Oct3/4 and CD34. Data were subjected to three-way analysis of variance (n = 6/group). The ANOVA tests were complemented by Tukey's or t-tests (p < 0.05). The variables "donor age" and "technique" were analyzed to define the optimal desirability value using a response optimization. DPSCs presented a high proliferation rate from passages 2 to 5 while cells from passage 8 proliferated at a slower rate. For all markers, no significant difference was observed among passages, irrespective of the technique used or the donor's age. The mean fraction of specific antibodies was 73.7% (± 11.5), 49.0% (± 18.7), 80.1% (± 8.0), 45.2% (± 13.7), 64.7% (± 5.3) and 2.0% (± 1.5) for CD44, OCT, vimentin, nestin, CD146 and CD34, respectively. The highest optimal desirability value was obtained using the ED technique and cells from younger patients (d = 0.92). However, it was concluded that neither the isolation technique nor the donor age or cell passage significantly interfered with the stem cell phenotype and proliferation rate during cell expansion.

Abstract
The development of efficient insulin producing cells (IPC) induction system is fundamental for the regenerative clinical applications targeting Diabetes Mellitus. This study was set to generate IPC from human dental pulp stem cells (hDPSCs) capable of surviving under hypoxic conditions in vitro and in vivo. METHODS hDPSCs were cultured in IPCs induction media augmented with Cerium or Yttrium oxide nanoparticles along with selected growth factors & cytokines. The generated IPC were subjected to hypoxic stress in vitro to evaluate the ability of the nanoparticles to combat hypoxia. Next, they were labelled and implanted into diabetic rats. Twenty eight days later, blood glucose and serum insulin levels, hepatic hexokinase and glucose-6-phosphate dehydrogenase activities were measured. Pancreatic vascular endothelial growth factor (VEGF), pancreatic duodenal homeobox1 (Pdx-1), hypoxia inducible factor 1 alpha (HIF-1α) and Caspase-3 genes expression level were evaluated. RESULTS hDPSCs were successfully differentiated into IPCs after incubation with the inductive media enriched with nanoparticles. The generated IPCs released significant amounts of insulin in response to increasing glucose concentration both in vitro & in vivo. The generated IPCs showed up-regulation in the expression levels of anti-apoptotic genes in concomitant with down-regulation in the expression levels of hypoxic, and apoptotic genes. The in vivo study confirmed the homing of PKH-26-labeled cells in pancreas of treated groups. A significant up-regulation in the expression of pancreatic VEGF and PDX-1 genes associated with significant down-regulation in the expression of pancreatic HIF-1α and caspase-3 was evident. CONCLUSION The achieved results highlight the promising role of the Cerium & Yttrium oxide nanoparticles in promoting the generation of IPCs that have the ability to combat hypoxia and govern diabetes mellitus.

Abstract
Background Stem cells from human exfoliated deciduous teeth (SHED) are regarded as an attractive cell source for tissue regeneration. However, the effect of different levels of root resorption on the characteristics of SHED remains less understood. Thus, the tooth source that is most suitable for the isolation of SHEDs needs to be determined. To compare cellular and biological characteristics of stem cells from human exfoliated deciduous posterior teeth with varying levels of root resorption. Methods The pulp was obtained from the deciduous posterior teeth depending on the level of root resorption, and isolated SHEDs were grouped as follows: Teeth with 0 to 1/3rd root resorption as SHEDs (G1) and 1/3rd to 2/3rd root resorption as SHEDs (G2). Teeth were also collected from >2/3rd root resorption status, but failed to establish primary culture of SHED as the availability of pulp tissue was too less. Later, isolated SHEDs were compared on their morphology, viability, growth kinetics, colony-forming ability, expression of cell surface markers and in vitro differentiation into osteocytes and adipocytes. Results No major differences were observed in terms of cellular morphology, viability, proliferation rate, colony-forming ability, cell surface markers expression, and mesenchymal lineage differentiation of SHEDs isolated from posterior teeth with 0 to 1/3rd and 1/3rd to 2/3rd root resorption. However, SHED from teeth with 0 to 1/3rd root resorption (G1) displayed relatively higher proliferation capacity and expression of selected markers. Conclusions Collectively, SHEDs (G1) and SHEDs (G2) showed comparable cellular and biological characteristics that enable their possible applications in regenerative therapies.

Abstract
Mesenchymal stem cells (MSCs) can be harvested from different sites in the oral cavity, representing a reservoir of cells useful for regenerative purposes. As direct comparisons between at least two types of MSCs deriving from the same patient are surprisingly rare in scientific literature, we isolated and investigated the osteoinductive potential of dental pulp stem cells (DPSCs) and buccal fat pad stem cells (BFPSCs). MSCs were isolated from the third molar dental pulp and buccal fat pads of 12 patients. The number of viable cells was quantified through manual count. Proliferation and osteodifferentiation assays, flow cytometry analysis of cell phenotypes, and osteocalcin release in vitro were performed. The isolation of BFPSCs and DPSCs was successful in 7 out of 12 (58%) and 3 out of 12 (25%) of retrieved samples, respectively. The yield of cells expressing typical stem cell markers and the level of proliferation were higher in BFPSCs than in DPSCs. Both BFP-SCs and DPSCs differentiated into osteoblast-like cells and were able to release a mineralized matrix. The release of osteocalcin, albeit greater for BFPSCs, did not show any significant difference between BFPSCs and DPSCs. The yield of MSCs depends on their site of origin as well as on the protocol adopted for their isolation. Our data show that BFP is a valuable source for the derivation of MSCs that can be used for regenerative treatments.

Abstract
Efficiency of the induction protocol is crucial for the generation of insulin-producing cells (IPCs) from human dental pulp stem cells (hDPSCs). Here, we established the integrative induction protocol by merging genetic manipulation technique with our previous published 3-step induction protocol aiming to enhance the pancreatic progenitor commitment and production yield. We found that the overexpression of PDX1 following with 3-step induction protocol were able to generate the 3-dimensional (3D) colony structure of pancreatic progenitors (PPs) with the beneficial trends of pancreatic endoderm commitment and production yield, while other protocols using the prolong maintenance of PDX1-overexpressed hDPSCs and the PDX1 overexpression after definitive endoderm induction were unable to generate and sustain the 3D structure of the colonies. Further Notch signaling manipulation by DAPT treatment showed lesser degree of positive effects on progenitor commitment and production yield. Although the generated PPs from the integrative protocol expressed pancreatic mRNA markers along with pro-insulin and insulin proteins, they still contained the defective glucose-responsive C-peptide secretion. Only basal secreted C-peptide level was observed. In summary, the integrative induction protocol potentially enhanced the PP generation with high colony production yield and could serve as an efficient platform for further hDPSC-derived IPC production and maturation.
