Alveolar cleft reconstruction using bone marrow aspirate concentrate and iliac cancellous bone: A 12-month randomized clinical study. Clin Oral Investig 2023; 27:6667-6675. [PMID: 37794139 PMCID: PMC10630224 DOI: 10.1007/s00784-023-05276-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Accepted: 09/23/2023] [Indexed: 10/06/2023]
Abstract
OBJECTIVE This study aimed to compare the bone density and volume in patients with alveolar cleft reconstructions utilizing bone marrow aspirate concentrate with iliac graft versus iliac graft alone. MATERIAL AND METHODS Thirty-six patients with unilateral alveolar cleft were randomly allocated into either an intervention group receiving an iliac bone graft mixed with bone marrow concentrate or a control group receiving an iliac bone graft. Cone beam CT was obtained preoperative, 6 and 12 months postoperatively to assess the bone density of the graft and bone volume of the alveolar defect, and then, the bone loss ratio was calculated. RESULTS Bone volume and bone density demonstrated a statistically significant increase in the intervention group at 6 and 12 months. In contrast, the bone loss ratio decreased significantly in the intervention group throughout the follow-up period. CONCLUSION A combination of bone marrow concentrate and iliac cancellous bone in alveolar cleft reconstruction may improve bone densities and volume in addition to decreasing graft loss rate. CLINICAL SIGNIFICANCE Using of bone marrow aspirate concentrate will decrease the amount of the graft needed and decrease the ratio of bone loss at the grafted site by the time. Trial registration ClinicalTrials.org ( NCT04414423 ) 4/6/2020.

Abstract
This study was conducted to review the efficacy of different sources of stem cells in bone regeneration of cleft palate patients. The majority of previous studies focused on the transplantation of bone marrow mesenchymal stem cells. However, other sources of stem cells have also gained considerable attention, and dental stem cells have shown especially favorable outcomes. Additionally, approaches that apply the co-culture and co-transplantation of stem cells have shown promising results. The use of different types of stem cells, based on their accessibility and efficacy in bone regeneration, is a promising method in cleft palate bone regeneration. In this regard, dental stem cells may be an ideal choice due to their efficacy and accessibility. In conclusion, stem cells, despite the lengthy procedures required for culture and preparation, are a suitable alternative to conventional bone grafting techniques.

Abstract
OBJECTIVES This study aimed to evaluate and compare the early biological effects of allogeneic bone marrow-derived mesenchymal stem cells (BMSCs) versus salmon calcitonin (SC) on healing of surgically induced mandibular bone defects in osteoporotic rats. METHODS Sixty-one female albino rats were included in this study, four of them were used for BMSCs isolation. The remaining 57 rats were divided into 4 groups. Group I (negative control), 12 rats received a vehicle injection after which a unilateral mandibular defect was created in each rat. Osteoporosis was induced in the remaining 45 rats then rats were randomly allocated into 3 equal groups (15 each). Surgical defects were created as in group I. The defects were left to heal spontaneously in group II; positive control. While in group III each defect was filled with an absorbable hemostatic gelatin sponge loaded by 10 IU of injectable SC and in group IV the sponge was seeded by 0.5 × 106 BMSCs. Rats were euthanized at 1st, 2nd, and 4th week postsurgically. Hematoxylin and eosin, Masson's trichrome, picrosirius, and alizarin red s stains were used, followed by statistical analysis. RESULTS BMSCs-treatment showed marked enhanced bone healing. Moreover, collagen fibers and calcium deposits area percentages were statistically significantly higher when compared to the other groups particularly at 2 and 4 weeks. CONCLUSIONS Local application of bone marrow-derived mesenchymal stem cells and salmon calcitonin may be an effective therapy for treatment of osteoporotic bone defects, with privilege to the stem cells in terms of quantity and quality of regenerated bone.

Abstract
Scaffold materials for bone regeneration are crucial for supporting endogenous healing after accidents, infections, or tumor resection. Although beneficial impacts of microtopological or nanotopological cues in scaffold topography are commonly acknowledged, less consideration is given to the interplay between the microscale and nanoscale. Here, micropores with a 60.66 ± 24.48 µm diameter ordered by closely packed collagen fibers are identified in pre-wetted Spongostan, a clinically-approved collagen sponge. On a nanoscale level, a corrugated surface of the collagen sponge is observable, leading to the presence of 32.97 ± 1.41 nm pores. This distinct micro- and nanotopography is shown to be solely sufficient for guiding osteogenic differentiation of human stem cells in vitro. Transplantation of Spongostan into a critical-size calvarial rat bone defect further leads to fast regeneration of the lesion. However, masking the micro- and nanotopographical cues using SiO2 nanoparticles prevents bone regeneration in vivo. Therefore, we demonstrate that the identified micropores allow migration of stem cells, which are further driven towards osteogenic differentiation by scaffold nanotopography. The present findings emphasize the necessity of considering both micro- and nanotopographical cues to guide intramembranous ossification, and might provide an optimal cell- and growth-factor-free scaffold for bone regeneration in clinical settings.

Abstract
Using three-dimensional (3D) bone engineering to fabricate bone segments is a better choice for repairing bone defects than using autologous bone. However, biomaterials for bone engineering are burdened with some clinical safety concerns. In this study, we layered commonly found clinical materials, hemostatic gelatin sponges, in a novel manner to create a 3D scaffold for bone engineering purposes. We further examined the comparable benefits of our design with both closed- and open-bottom holders. Cells in stacked layer disc systems were examined after a week of growth and differentiation. Osteoblasts in the outer layers of both closed- and open-bottom holder systems displayed gradually increased alkaline phosphatase (ALP) activity but decreased osteopontin (OPN) expression. Further, cell proliferation assays and LIVE/DEAD staining revealed decreased viable cell counts in the top layer with increased incubation time. However, while layered disc systems with closed-bottom holders underwent differentiation, they kept more differentiated cells alive within the gelatin sponge disc scaffold after 28 d of culturing. Whether cells were inoculated into the top, middle, or bottom portions of the layered disc stack, osteoblasts showed a preference for migrating to the top layer, in keeping with the oxygen and nutrients gradients. Regarding practical application, this study offers valuable information to promote the use of hemostatic gelatin sponges for bone engineering.

Abstract
Objective Repairing bone defects, especially in older individuals with limited regenerative capacity, is still a big challenge. The use of biomimetic materials that can enhance the restoration of bone structure represents a promising clinical approach. In this study, we evaluated ectopic bone formation after the transplantation of human maxillary Schneiderian sinus membrane- (hMSSM-) derived cells embedded within various scaffolds in the femur of pigs. Methods The scaffolds used were collagen, gelatin, and hydroxyapatite/tricalcium phosphate (HA/βTCP) where fibrin/thrombin was used as a control. Histological analysis was performed for the new bone formation. Quantitative real-time PCR (qRT-PCR) and immunohistochemistry (IHC) were used to assess mRNA and protein levels of specific osteoblastic markers, respectively. Results Histological analysis showed that the three scaffolds we used can support new bone formation with a more pronounced effect observed in the case of the gelatin scaffold. In addition, mRNA levels of the different tested osteoblastic markers Runt-Related Transcription Factor 2 (RUNX-2), osteonectin (ON), osteocalcin (OCN), osteopontin (OPN), alkaline phosphatase (ALP), and type 1 collagen (COL1) were higher, after 2 and 4 weeks, in cell-embedded scaffolds than in control cells seeded within the fibrin/thrombin scaffold. Moreover, there was a very clear and differential expression of RUNX-2, OCN, and vimentin in osteocytes, osteoblasts, hMSSM-derived cells, and bone matrix. Interestingly, the osteogenic markers were more abundant, at both time points, in cell-embedded gelatin scaffold than in other scaffolds (collagen, HA/βTCP, fibrin/thrombin). Conclusions These results hold promise for the development of successful bone regeneration techniques using different scaffolds embedded with hMSSM-derived cells. This trial is registered with NCT02676921.

Abstract
Objectives:A variety of bioreactors and related approaches have been applied to dental tissues as their use has become more essential in the field of regenerative dentistry and dental tissue engineering. The review discusses the various types of bioreactors and their potential application in dentistry.Methods:Review of the literature was conducted using keywords (and MeSH) like Bioreactor, Regenerative Dentistry, Fourth Factor, Stem Cells, etc., from the journals published in English. All the searched abstracts, published in indexed journals were read and reviewed to further refine the list of included articles. Based on the relevance of abstracts pertaining to the manuscript, full-text articles were assessed.Results:Bioreactors provide a prerequisite platform to create, test, and validate the biomaterials and techniques proposed for dental tissue regeneration. Flow perfusion, rotational, spinner-flask, strain and customize-combined bioreactors have been applied for the regeneration of bone, periodontal ligament, gingiva, cementum, oral mucosa, temporomandibular joint and vascular tissues. Customized bioreactors can support cellular/biofilm growth as well as apply cyclic loading. Center of disease control & dip-flow biofilm-reactors and micro-bioreactor have been used to evaluate the biological properties of dental biomaterials, their performance assessment and interaction with biofilms. Few case reports have also applied the concept of in vivo bioreactor for the repair of musculoskeletal defects and used customdesigned bioreactor (Aastrom) to repair the defects of cleft-palate.Conclusions:Bioreactors provide a sterile simulated environment to support cellular differentiation for oro-dental regenerative applications. Also, bioreactors like, customized bioreactors for cyclic loading, biofilm reactors (CDC & drip-flow), and micro-bioreactor, can assess biological responses of dental biomaterials by simultaneously supporting cellular or biofilm growth and application of cyclic stresses.

Abstract
BACKGROUND Novel treatments for bone defects, particularly in patients with poor regenerative capacity, are based on bone tissue engineering strategies which include mesenchymal stem cells (MSCs), bioactive factors, and convenient scaffold supports. OBJECTIVE In this study, we aimed at comparing the potential for different scaffolds to induce osteogenic differentiation of human maxillary Schneiderian sinus membrane- (hMSSM-) derived cells. Methods. hMSSM-derived cells were seeded on gelatin, collagen, or Hydroxyapatite β-Tricalcium phosphate-Fibrin (Haβ-TCP-Fibrin) scaffolds. Cell viability was determined using an MTT assay. Alizarin red staining method, Alkaline phosphatase (ALP) activity assay, and quantitative real-time PCR analysis were performed to assess hMSSM-derived cells osteogenic differentiation. RESULTS Cell viability, calcium deposition, ALP activity, and osteoblastic markers transcription levels were most striking in gelatin scaffold-embedded hMSSM-derived cells. CONCLUSION Our findings suggest a promising potential for gelatin-hMSSM-derived cell construct for treating bone defects.

Abstract
PURPOSE To compare the volumetric changes in successfully treated clefts with secondary alveolar grafting using recombinant human bone morphogenic protein-2 (rhBMP-2) delivered in β-tricalcium phosphate (βTCP) scaffold versus autogenous grafts obtained from the iliac crest and mandibular symphysis. PATIENTS AND METHODS We performed a retrospective cohort study of cone-beam computed tomography scans of 25 subjects with unilateral or bilateral clefts. Of the 25 patients, 7 received an iliac crest bone graft, 9 received a mandibular symphyseal bone graft, and 9 subjects received the rhBMP-2/βTCP bone substitute. Volumetric rendering software was used to calculate the amount of new bone formation and residual bone defect present in the cleft area. The data were analyzed using Wilcoxon and Kruskal-Wallis tests and Pearson's correlation coefficient. RESULTS The mean percentage of new bone formation for the iliac crest, symphysis, and rhBMP-2/βTCP was 85.47, 80.56, and 81.22%, respectively (P = .0854). The initial cleft volume had a weak positive correlation with the percentage of new bone formation (r = 0.18), but the postoperative residual cleft volume had a strong negative correlation (r = 0.71). CONCLUSIONS rhBMP2 delivered in a βTCP scaffold in alveolar cleft patients can be a viable alternative to autogenous iliac crest and symphysis grafts, eliminating donor site morbidity.

Abstract
Alveolar (gumline) clefts are the most common congenital bone defect in humans, affecting 1 in 700 live births. Treatment to repair these bony defects relies on autologous, cancellous bone transfer from the iliac crest. This harvest requires a second surgical site with increased surgical time associated with potential complications, while providing only limited cancellous bone. Improvements in treatment protocols that avoid these limitations would be beneficial to patients with clefts and other craniofacial bone defects. There have been steady advances in tissue-engineered (TE) solutions for long-bone defects and adult patients, but advances for the pediatric craniofacial skeleton have been slower to emerge. This study utilizes a previously established juvenile swine model with a surgically created, critical size alveolar defect to test the efficacy of umbilical cord (UC) mesenchymal stem cells (MSCs) treatments on nano-microfiber scaffolds. At 1 month after implanting our TE construct, mineralized tissue in the surgical gap was quantified through computed tomography (CT), and histology, and excised tissue was subjected to mechanical testing. Both undifferentiated and predifferentiated (toward an osteogenic lineage) UC MSCs generated bone within the cleft on a scale comparable to iliac crest cancellous bone, as evidenced by histology and CT scans. All of the pigs treated with scaffold/stem cell combinations had mineralized tissue within the defect, although without filling the entire defect. Several of the experimental animals exhibited poor and/or asymmetric maxillary growth 1 month after the initial surgery, especially if the surgical defect was located on the smaller side of an already asymmetric pig. Our results demonstrate that tissue engineering approaches using UC MSCs are a promising alternative for repair of the alveolar cleft. Data in the pig model demonstrate that implanted scaffolds are at least as good as the current gold standard treatment based on harvesting cancellous bone from the iliac crest, regardless of whether the cells seeded on the scaffold are precommitted to an osteogenic fate.

Abstract
Bone tissue engineering provides many advantages for repairing skeletal defects. Although many different kinds of biomaterials have been used for bone tissue engineering, safety issues must be considered when using them in a clinical setting. In this study, we examined the effects of using a common clinical item, a hemostatic gelatin sponge, as a scaffold for bone tissue engineering. The use of such a clinically acceptable item may hasten the translational lag from laboratory to clinical studies. We performed both degradation and biocompatibility studies on the hemostatic gelatin sponge, and cultured preosteoblasts within the sponge scaffold to demonstrate its osteogenic differentiation potential. In degradation assays, the gelatin sponge demonstrated good stability after being immersed in PBS for 8 weeks (losing only about 10% of its net weight and about 54% decrease of mechanical strength), but pepsin and collagenases readily biodegraded it. The gelatin sponge demonstrated good biocompatibility to preosteoblasts as demonstrated by MTT assay, confocal microscopy, and scanning electron microscopy. Furthermore, osteogenic differentiation and the migration of preosteoblasts, elevated alkaline phosphatase activity, and in vitro mineralization were observed within the scaffold structure. Each of these results indicates that the hemostatic gelatin sponge is a suitable scaffold for bone tissue engineering.

Abstract
Numerous bone and soft tissue grafting techniques are followed to repair cleft of lip and palate (CLP) defects. In addition to the gold standard surgical interventions involving the use of autogenous grafts, various allogenic and xenogenic graft materials are available for bone regeneration. In an attempt to discover minimally invasive and cost effective treatments for cleft repair, an exceptional growth in synthetic biomedical graft materials have occurred. This study gives an overview of the use of dental materials to repair cleft of lip and palate (CLP). The eligibility criteria for this review were case studies, clinical trials and retrospective studies on the use of various types of dental materials in surgical repair of cleft palate defects. Any data available on the surgical interventions to repair alveolar or palatal cleft, with natural or synthetic graft materials was included in this review. Those datasets with long term clinical follow-up results were referred to as particularly relevant. The results provide encouraging evidence in favor of dental and other related biomedical materials to fill the gaps in clefts of lip and palate. The review presents the various bones and soft tissue replacement strategies currently used, tested or explored for the repair of cleft defects. There was little available data on the use of synthetic materials in cleft repair which was a limitation of this study. In conclusion although clinical trials on the use of synthetic materials are currently underway the uses of autologous implants are the preferred treatment methods to date.

Abstract
Achieving a successful and well-functioning reconstruction of craniofacial deformities still remains a challenge. As for now, autologous bone grafting remains the gold standard for alveolar cleft reconstruction. However, its aesthetic and functional results often remain unsatisfactory, which carries a long-term psychosocial and medical sequelae. Therefore, searching for novel therapeutic approaches is strongly indicated. With the recent advances in stem cell research, cell-based tissue engineering strategies move from the bench to the patients' bedside. Successful stem cell engineering employs a carefully selected stem cell source, a biodegradable scaffold with osteoconductive and osteoinductive properties, as well as an addition of growth factors or cytokines to enhance osteogenesis. This review highlights recent advances in mesenchymal stem cell tissue engineering, discusses animal models and case reports of stem cell enhanced bone regeneration, as well as ongoing clinical trials.

Abstract
BACKGROUND Autologous bone graft has been regarded as the criterion standard for the repair of alveolar cleft. However, the most prominent issue in alveolar cleft treatment is the high absorption rate of the bone graft. The authors' objective was to investigate the effects of an autologous iliac bone, bone marrow-derived mesenchymal stem cell, and platelet-rich fibrin mixture on the repair of dog alveolar cleft. METHODS Twenty beagle dogs with unilateral alveolar clefts created by surgery were divided randomly into four groups: group A underwent repair with an autologous iliac bone, bone marrow-derived mesenchymal stem cell, and platelet-rich fibrin mixture; group B underwent repair with autologous iliac bone and bone marrow-derived mesenchymal stem cells; group C underwent repair with autologous iliac bone and platelet-rich fibrin; and group D underwent repair with autologous iliac bone as the control. One day and 6 months after transplantation, the transplant volumes and bone mineral density were assessed by quantitative computed tomography. All of the transplants were harvested for hematoxylin and eosin staining 6 months later. RESULTS Bone marrow-derived mesenchymal stem cells and platelet-rich fibrin transplants formed the greatest amounts of new bone among the four groups. The new bone formed an extensive union with the underlying maxilla in groups A, B, and C. Transplants with the bone marrow-derived mesenchymal stem cells, platelet-rich fibrin, and their mixture retained the majority of their initial volume, whereas the transplants in the control group showed the highest absorption rate. Bone mineral density of transplants with the bone marrow-derived mesenchymal stem cells, platelet-rich fibrin, and their mixture 6 months later was significantly higher than in the control group (p < 0.05), and was the highest in bone marrow-derived mesenchymal stem cells and platelet-rich fibrin mixed transplants. Hematoxylin and eosin staining showed that the structure of new bones formed the best in group A. CONCLUSION Both bone marrow-derived mesenchymal stem cells and platelet-rich fibrin are capable of improving the repair of dog alveolar cleft, and the mixture of them is more potent than each one of them used singly for enhancing new bone regeneration.

Abstract
INTRODUCTION Ortho dontico-surgical coverage of alveolar crack is essential in reason of its repercussions on facial growth and implementation of children's teeth set. We proposed to realize a premature gingivo periosto plastic surgery from 4 years old by osseous substitute to lower age of alveolar cracks closure and decrease the morbidity of patients. PATIENTS AND METHODS We conducted a retrospective study over one year (January, 2012 to December, 2012), with six months postoperatively outcomes, on 23 cases of gingivo periosto plastic sugary with osseous substitute type glass by bone transplant at infantile plastic surgery service of Timone - Children teaching hospital of Marseille, France. RESULTS We held 23 patients. Seventeen children, 12 boys and 5 girls presented unilateral cracks. Twenty patients required a quantity of glass bone under 1cc for the narrow cracks. Prevalence of the mucous cracks was low (4 cases on 23). Technique of gingivo periosto plastic surgery with osseous substitute is simple and our results are globally satisfactory. We observed less morbidity of the operating site. CONCLUSION The first results of this study showed that gingivo periosto plastic surgery with osseous substitute glass bone is a simple, reliable and reproducible technique, with promising results. Reduction of site's morbidity by osseous transplant, accessibility of glass bone cost and simplicity of surgical gesture justified adoption of this technique.

Abstract
OBJECTIVES The aim of this study was to evaluate HA coated with different ratios of TCP as a carrier for hABMSCs obtained during implant osteotomy in comparison to slowly-resorbing biomaterial, Bio-Oss, as a negative control, using in vitro and in vivo experiments. MATERIALS AND METHODS Human ABMSCs (hABMSCs) harvested during implant osteotomy were transplanted using HA/TCP or Bio-Oss as carriers in a murine ectopic transplantation model (n = 12). Pore size and cell affinity were evaluated in vitro. The area of newly formed bone was analyzed histometrically, the number of osteocytes was counted, and immunohistochemical staining was conducted against several markers of osteogenesis, including alkaline phosphatase (ALP), runt-related transcription factor 2 (RUNX-2), osteocalcin (OCN), and osteopontin (OPN). Osteoclast formation was evaluated by tartrate-resistant acid phosphatase staining. RESULTS The carrier materials had comparable pore sizes. The cell affinity assay resulted in a high proportion of cell adhesion (>90%) in all experimental groups. Substantial new bone and osteocyte formation was observed on both HA/TCP carriers, whereas it was minimal with Bio-Oss. Positive immunostaining for ALP, RUNX-2, OCN, and OPN was observed with HA/TCP, but only limited expression of osteogenic markers with Bio-Oss. Conversely, there was a minimal osteoclast presence with Bio-Oss, but a significant presence of osteoclasts with both HA/TCP carriers. CONCLUSIONS Both types of scaffolds, BCP and Bio-Oss, showed high stem cell-carrying potential, but the in vivo healing patterns of their complexes with hABMSC could be affected by the microenvironment on the surfaces of the scaffolds.

Abstract
With advancements in biological and engineering sciences, the definition of an ideal biomaterial has evolved over the past 50 years from a substance that is inert to one that has select bioinductive properties and integrates well with adjacent host tissue. Biomaterials are a fundamental component of tissue engineering, which aims to replace diseased, damaged, or missing tissue with reconstructed functional tissue. Most biomaterials are less than satisfactory for pediatric patients because the scaffold must adapt to the growth and development of the surrounding tissues and organs over time. The pediatric community, therefore, provides a distinct challenge for the tissue engineering community.

Abstract
UNLABELLED The development of sufficient tissue engineered bone grafts for alveolar cleft osteoplasty could reduce the necessity of autogenous bone grafts and its donor site morbidity. The aim of the study was to evaluate tissue engineered bone grafts in an artificially created bone defect. Bone grafts were created in vitro colonizing a synthetic hydroxyapatite-tricalciumphosphate scaffold (BONITmatrix(®)) with either undifferentiated mesenchymal stromal cells (group 1) or osteogenic differentiated mesenchymal stromal cells (group 2). Cells were multiplied from bone marrow of donor rats. Unmodified scaffolds (group 3) and the tissue engineered bone grafts were inserted into artificial maxillary defects of 54 Lewis rats. In 18 animals the defects remained unfilled (control). After one, three and six weeks the rats were sacrificed. The defect was evaluated radiologically and histologically with regard to the remaining defect volume and diameter. Statistical analysis followed. The bone grafts led to a specific bone formation at the defect margin. No complete reunion of any defect was observed within the healing time. After six weeks, the remaining defect volume was 6.86 ± 3.21 mm(3) (control), 4.08 ± 1.36 mm(3) (group 1), 5.00 ± 0.84 mm(3) (group 2) 5.50 ± 1.05 mm(3) (group 3). The remaining defect diameter measured 2.63 ± 0.52 mm (control), 2.39 ± 0.23 mm (group 1), 2.53 ± 0.22 mm (group 2) and 2.70 ± 0.66 mm (group 3). In all experimental groups the defect volume and diameter decreased over time, which was significant for group 1 (p = 0.014), group 2 (p = 0.025) and group 3 (p = 0.048). The defect volume and width was significantly reduced for bone grafts containing undifferentiated cells compared to control (p = 0.035) or scaffolds only (p = 0.05). CONCLUSION Tissue engineered bone grafts induce a pronounced bone formation in artificial bone defects compared to unfilled controls or scaffolds only.

Abstract
AIM Due to a lack of regenerative potential, current treatments for periodontal defects do not always provide satisfactory clinical results. Previously, the implantation of a biomaterial scaffold-cell construct has been suggested as a clinically achievable approach. In this study, it was aimed to investigate the contribution of implanted periodontal ligament (PDL) cells to periodontal tissue regeneration. MATERIALS & METHODS Gelatin sponges were seeded with green fluorescent protein (GFP) transfected PDL or gingival fibroblasts (GF) cells, and implanted into a surgically created rat intrabony periodontal defect model. After six weeks, decalcified maxillae were used for histomorphometrical and immunohistochemical analyses. RESULTS After six weeks, animals that had received the PDL cells exhibited significantly more functional bone and ligament. Furthermore, there were remarkable differences in the distribution of the transplanted cells. Periodontal ligament cells were always located directly lining the newly regenerated areas. In contrast, GF cells dispersed over the whole defect area, and did not provide a favourable effect on the regeneration of the periodontal tissues. CONCLUSION We concluded that PDL cells transplanted into a periodontal defect survive and favour regeneration of periodontium, possibly in a paracrine manner.

Abstract
Patients with clefts of the lip and palate commonly develop maxillary hypoplasia. In addition to orthognathic surgery, augmentation of the anterior maxilla may be necessary in these patients to restore symmetry to the nasomaxillary complex. Bone graft may be obtained from numerous sites. All require a separate incision at the donor site and may result in additional morbidity.The authors describe a 16-year-old with a complete right unilateral cleft of the lip and palate who underwent maxillary advancement at the Le Fort I level. Pronounced sagittal deficiency of the maxilla necessitated osseous augmentation. The patient's deformity resulted in deviation of the superior vomer bone. This bone was of adequate quality to be used as an onlay graft for the maxilla. This is the first report documenting the use of vomer as a bone graft for maxillary augmentation.

Abstract
We examined cytokine production by bone marrow stromal cells (BMSCs) of patients with multiple myeloma (MM) in response to contact with myeloma RPMI8226 cells in standard 2-dimensional (2D) cultures and in 3-dimensional (3D) cultures on a gelatine sponge scaffold. It was detected that BMSCs in the 3D cultures produced more IL-11 and HGF and less IL-10 than in the 2D cultures. Moreover, RPMI8226 cells after contact with BMSCs in 3D cultures produced more sIL-6R than in the classic 2D cultures. We concluded that 3D cultures of BMSCs with myeloma cells offered a promising model for in vitro examination of interactions between myeloma cells and the bone marrow stroma and for examination of potent antimyeloma agents.

Abstract
PURPOSE Clefts of the lip and palate are the most prevalent congenital craniofacial birth defect in humans. The developing field of tissue engineering is considered for the management of clefts of the lip and palate. MATERIALS AND METHODS A review of the literature was carried out by using electronic databases (such as PubMed and ISI Web of Science) to search topics including "cleft palate," "tissue engineering," "bone engineering," "palate engineering," and "alveolar bone grafting." To reflect current practice and research, these searches were limited primarily to articles published after the year 2000. RESULTS Current approaches for the treatment of clefts of the lip and palate include surgery and bone grafts; however, there are limitations associated with these therapies. Tissue engineering strategies, particularly alveolar bone engineering and soft tissue engineering, may provide clinicians with new alternatives. The application of these emerging technologies to a pediatric population must be well considered. CONCLUSIONS A tissue engineering approach may be a useful alternative for the treatment of cleft palates as it mitigates the concerns of donor site morbidity as well as provides additional options including scaffold implantation and growth factor delivery.

Abstract
INTRODUCTION Position of medical devices has increased for last 30 years in otorhinolaryngology. Legal directive of use, main indications and perspectives are presented. RESULTS AND DISCUSSION Biomaterials are medical devices planned for tissue reconstruction or substitution. The approval labelling are planned in Europe by the European Community certification (marquage CE) and overseen by a postmarket medical device safety (matériovigilance), that are completely independent from the Food and Drug Administration certification. Indications of biomaterials are likely competitive to those of autografts; their advantage is to limit the morbidity due to autograft harvesting. Benefits are aesthetics, functional or complementary. Main indications are presented in otology, rhinology, face traumatology, laryngology, anti-aging surgery, implants and epithesis. Research fields are scanned (increased therapeutic properties, drug delivery systems, tissue engineering...). CONCLUSION Biomaterials are increasingly implanted in ENT surgery. The surgical success of their use require a strict legal label and well-defined indications.

Abstract
The projected annual demand for stem cell-based dental treatments in the United States can range from over 290 million tooth restorative treatments to 30,000 patients requiring tissue regeneration following craniofacial cancer surgery. Professional dental treatments cost Americans over $60 billion per year. Scientific advances in stem cell technologies, tissue engineering, and transplantation will provide the basis for the introduction of new treatment technologies into dentistry. This review provides an assessment of how stem cell therapies will likely change dental practice. The problems of introducing stem cell therapies are substantial, but they provide the best hope for many patients with congenital defects, and to regenerate teeth and tissues lost because of disease, cancer, and trauma, or missing because of congenital malformation. The most expensive dental treatments may be the most attractive candidates for stem cell therapies. This would indicate that craniofacial reconstruction, implants, and endodontic treatments are the most valuable applications of dental stem cell therapies, whereas tooth restorations and other dental treatments are the less commercially valuable.
