Abstract
A 5-year-old Miniature Dachshund was presented having an infrabony pocket on the palatal aspect of the right maxillary canine tooth. The bony defect had worsened despite previous closed root planing and administration of a perioceutic agent. A second surgery using an allogeneic cancellous bone augmentation with an enamel matrix derivative was performed in the infrabony defect following open root planing. Eight months after the periodontal surgery, the osseous defect showed healing by improved periodontal probing measurements and increased radiopacity using dental radiography and computed tomography.

Abstract
Skin scarring and fibrosis affect millions of people worldwide, representing a serious clinical problem causing physical and psychological challenges for patients. Stem cell therapy and regenerative surgery represent a new area of treatment focused on promoting the body's natural ability to repair damaged tissue. Adipose-derived stem cells (ASCs) represent an optimal choice for practical regenerative medicine due to their abundance, autologous tissue origin, non-immunogenicity, and ease of access with minimal morbidity for patients. This review of the literature explores the current body of evidence around the use of ASCs-based regenerative strategies for the treatment of scarring and skin fibrosis, exploring the different surgical approaches and their application in multiple fibrotic skin conditions. Human, animal, and in vitro studies demonstrate that ASCs present potentialities in modifying scar tissue and fibrosis by suppressing extracellular matrix (ECM) synthesis and promoting the degradation of their constituents. Through softening skin fibrosis, function and overall quality of life may be considerably enhanced in different patient cohorts presenting with scar-related symptoms. The use of stem cell therapies for skin scar repair and regeneration represents a paradigm shift, offering potential alternative therapeutic avenues for fibrosis, a condition that currently lacks a cure.

Abstract
INTRODUCTION Analysis of the 3-dimensional implant position, the bone defect morphology, and the soft tissue situation guides the decision to preserve or to remove an implant with a severe peri-implantitis lesion. The aim of this narrative review was to analyze and to comprehensively illustrate the treatment options focusing on peri-implant bone regeneration in presence of severe peri-implant bone loss. METHODS A database search was performed independently by the two reviewers to identify case reports, case series, cohort, retrospective, and prospective studies about peri-implant bone regeneration with a follow-up of at least 6 months. Of the 344 studies issued during the database analysis, 96 publications were selected by the authors for this review. RESULTS Deproteinized bovine bone mineral remains the best documented material for defect regeneration in peri-implantitis in combination with or without a barrier membrane. While studies using autogenous bone in peri-implantitis therapy are rarely found, they do report favorable potential of vertical bone regeneration. Moreover, while membranes are an inherent part of the guided bone regeneration, a 5-year follow-up study demonstrated clinical and radiographic improvements with and without a membrane. The administration of systemic antibiotics is frequently performed in clinical studies observing regenerative surgical peri-implantitis therapy, but the analysis of the literature does not support a positive effect of this medication. Most studies for regenerative peri-implantitis surgery recommend the removal of the prosthetic rehabilitation and the use a marginal incision with a full-thickness access flap elevation. This allows for a good overview for regenerative procedures with a certain risk of wound dehiscences and incomplete regeneration. An alternative approach referring to the poncho technique may reduce the risk of dehiscence. The effectiveness of implant surface decontamination might have an impact on peri-implant bone regeneration without any clinical superiority of a certain technique. CONCLUSION The available literature reveals that the success of peri-implantitis therapy is limited to the reduction of bleeding on probing, the improvement of the peri-implant probing depth and a small amount of vertical defect fill. On this basis, no specific recommendations for bone regeneration in surgical peri-implantitis therapy can be made. Innovative approaches for flap design, surface decontamination, bone defect grafting material, and soft tissue augmentation should be followed closely to find advanced techniques for favorable peri-implant bone augmentation.

Abstract
This case series presents three patients undergoing minimally invasive regenerative surgery for peri-implantitis using peri-implant excision and regenerative surgery (PERS). No report of a resolved inflammatory state with peri-implant bone loss following nonsurgical treatment was included in this case report. After the suprastructure of the implant was disconnected, a peri-implant circular incision was made to remove inflammatory tissue. The combination decontamination method was conducted using a chemical agent and a mechanical device. After copious irrigation with normal saline, collagenated demineralized bovine bone mineral was applied to fill the peri-implant defect. The suprastructure of the implant was connected following the PERS procedure. The three patients with peri-implantitis that underwent successfully PERS procedures suggest that surgical intervention is a feasible approach to obtaining proper peri-implant bone filling of 3.42 ± 1.08 mm. However, this novel technique should be investigated in a larger sample size to determine its reliability and validity.

Abstract
Both surgical and non-surgical techniques are employed for implant site development. However, the efficacy of these methods has not been thoroughly evaluated and compared. This systematic review aims to compare the biologic, functional and esthetic outcomes of three different approaches before implant placement in both the maxillary and mandibular arches: orthodontic extrusion, regenerative surgery and spontaneous healing after extraction. The systematic research of articles was conducted up to January 2020 in Medline, Scopus and the Cochrane Library databases. Studies were selected in a three-stage process according to the title, the abstract and the inclusion criteria. The methodological quality and the risk of bias of the included studies were evaluated using ROBINS-I tools for non-randomized studies, Rob 2.0 for RCT. Quality evaluation of case reports was performed using CARE guidelines. Through the digital search, 1607 articles were identified, and 25 of them were included in the systematic review. The qualitative evaluation showed a good methodological quality for RCT, sufficient for non-randomized studies and poor for case reports. Based on the available results, both orthodontic extrusion and regenerative surgery allowed the development of the implant site with satisfying esthetic and functional outcomes. Studies about the spontaneous healing of the extraction socket showed resorption of the edentulous ridge, which complicated the implant insertion. No study referred to failures or severe complications. Most of the studies reported only qualitative results. The present systematic review demonstrated that there is a substantial lack of data and evidence to determine which of the presented methods is better for developing a future implant site. Both surgical and non-surgical procedures appear effective in the regeneration of hard tissue, whereas not all the techniques can improve soft tissue volume, too. The orthodontic technique simultaneously enhances both hard and soft tissue.

Abstract
Background Associating liver partition and portal vein ligation (ALPPS) has evolved as a treatment strategy for patients with liver tumors who are not amenable for upfront hepatectomy because of an insufficient future liver remnant (FLR). Aim of this study was to test the applicability of ultrasound guided parenchyma sparing surgery to ALPPS concept, by non-anatomically shifting the plane of transection in favor of FLR, resulting in a new technical variant of ALPPS, entitled parenchyma sparing ALPPS (psALPPS). Materials and Methods Patients who could not safely undergo right trisectionectomy ALPPS because of insufficient FLR were considered eligible for psALPPS, consisting in liver partition through segment 4 using ultrasound guidance. Results Between April 2017 and April 2021, five patients with median age of 68 years (range: 66-78), four male and one female, underwent psALPPS for colorectal liver metastases (N=2), intrahepatic cholangiocarcinoma (N=2), and hepatocellular carcinoma (N=1). Standardized FLR (sFLR) for segments 2-3 before stage 1 surgery would have been a median of 11.6%. PsALPPS could double the sFLR at stage 1 resulting in an increase of ps-sFLR from a median of 22.7% (at stage 1) to 34.0% (at stage 2) after a median interstage interval of 15 days. All patients tolerated surgery well and no major complications were recorded. Conclusions Applying the principles of parenchyma sparing surgery to ALPPS offers the advantage to maximize FLR and simultaneously reduce ischemic injury of segment 4 compared to conventional ALPPS. In this way, psALPPS may markedly increase resectability while reducing morbidity.

Abstract
Development of methods for replacing human tissue defects based on scaffold technologies in regenerative surgery proves the prospects of this industry. High-tech manufacturing of scaffold matrices suggests complete replacement of obsolete methods of treatment with new developments in the near future. At the same time, additional studies devoted to these methods and their results are needed. One of the promising goals for development of scaffold technologies is creation of versatile materials used in various fields of regenerative medicine.

Abstract
The reconstruction of complex midface defects is a challenging clinical scenario considering the high anatomical, functional, and aesthetic requirements. In this study, we proposed a surgical treatment to achieve improved oral rehabilitation and anatomical and functional reconstruction of a complex defect of the maxilla with a vascularized, engineered composite graft. The patient was a 39-year-old female, postoperative after left hemimaxillectomy for ameloblastic carcinoma in 2010 and tumor-free at the 5-year oncological follow-up. The left hemimaxillary defect was restored in a two-step approach. First, a composite graft was ectopically engineered using autologous stromal vascular fraction (SVF) cells seeded on an allogenic devitalized bone matrix. The resulting construct was further loaded with bone morphogenic protein-2 (BMP-2), wrapped within the latissimus dorsi muscle, and pedicled with an arteriovenous (AV) bundle. Subsequently, the prefabricated graft was orthotopically transferred into the defect site and revascularized through microvascular surgical techniques. The prefabricated graft contained vascularized bone tissue embedded within muscular tissue. Despite unexpected resorption, its orthotopic transfer enabled restoration of the orbital floor, separation of the oral and nasal cavities, and midface symmetry and allowed the patient to return to normal diet as well as to restore normal speech and swallowing function. These results remained stable for the entire follow-up period of 2 years. This clinical case demonstrates the safety and the feasibility of composite graft engineering for the treatment of complex maxillary defects. As compared to the current gold standard of autologous tissue transfer, this patient’s benefits included decreased donor site morbidity and improved oral rehabilitation. Bone resorption of the construct at the ectopic prefabrication site still needs to be further addressed to preserve the designed graft size and shape.

Abstract
OBJECTIVES Evaluate in a case series the clinical applicability of a regenerative approach for treatment of peri-implant lesions based on papilla preservation flaps (PPF) and minimally invasive surgery (MIST). MATERIAL AND METHODS Twenty-one deep peri-implant defects in 21 patients were surgically accessed applying PPF and MIST. The exposed implant surface was decontaminated with the sequential application of mechanical devices and chemical agents. Bone substitutes alone or in combination with a collagen barrier were applied, according to the anatomy of the peri-implant lesion. Clinical and radiographic measurements were collected at baseline, post-surgery, 1 and 5 years. RESULTS Primary wound closure was obtained in 100% of the sites and maintained in 90% of the sites at 1 week. Bleeding on probing (BOP) was reduced from 100% at baseline to 28.6% at 1 year and to 42.8% at 5 years. The 1-year pocket reduction was 3.9 ± 1 mm. Residual probing depths (PD) were 4.1 ± 0.9 mm. PD remained stable up to 5 years. The radiographic bone gain was 2.5 ± 1.2 mm (mesial) and 2.5 ± 1.1 (distal) at 1-year and 2.3 ± 1.3 mm (mesial) and 2.6 ± 1.4 mm (distal) at 5 years. The radiographic resolution of the defect was 70.4% ± 19% (mesial) and 70.2% ± 22% (distal) at 1 year and 64.2% ± 21% (mesial) and 67.7% ± 21% (distal) at 5 years. All implants survived up to 5 years. A composite outcome of disease resolution shows consistent 1-year clinical improvements at all the treated sites and substantial 5-year stability. CONCLUSIONS PPF and MIST can be successfully applied for the regenerative treatment of peri-implant defects.

Abstract
BACKGROUND Nonsurgical treatment, resective surgery, reconstructive surgery, or combined approaches have been proposed for the treatment of peri-implantitis, with variable results. PURPOSE To evaluate the 1-year clinical and radiographic outcomes following combined resective and reconstructive surgical treatment with topical piperacillin/tazobactam antibiotic in the management of peri-implantitis. MATERIAL AND METHODS Forty-three patients diagnosed with peri-implantitis were included. Surgical treatment consisted of implantoplasty of the supra-crestal component of the defect, the application of a topical antibiotic solution over the implant surface, and subsequent reconstruction of the intra-osseous component of the peri-implant defect. The primary outcome was disease resolution, defined as the absence of bleeding on probing (BoP) and/or suppuration on probing (SoP), a peri-implant pocket probing depth (PPD) ≤5 mm, and no bone loss >0.5 mm 1 year after surgery. Secondary outcomes included changes in BoP, PPD, SoP, and peri-implant marginal bone levels. One implant per patient was included in the analysis. RESULTS The treatment success rate of the 43 dental implants included in the study was 86% at 1 year after surgery. Mean PPD and BoP decreased from 6.41 ± 2.11 mm and 100% at baseline to 3.19 ± 0.99 mm (p < 0.001) and 14% (p < 0.001) at 1 year, respectively. SoP was significantly reduced from 48.8% at baseline to 0% 1 year after surgery (p < 0.001). Radiographically, a mean defect fill of 2.64 ± 1.59 mm was recorded (p < 0.001). CONCLUSIONS The combination of a resective and reconstructive surgical approach together with locally delivered antibiotic achieved a high disease resolution rate after 1 year of follow-up and constitutes a viable option for the management of peri-implantitis.

Abstract
Osteoarthritis (OA) is a chronic debilitating disorder causing pain and gradual degeneration of weight-bearing joints with detrimental effects on cartilage volume as well as cartilage damage, generating inflammation in the joint structure. The etiology of OA is multifactorial. Currently, therapies are mainly addressing the physical and occupational aspects of osteoarthritis using pharmacologic pain treatment and/or surgery to manage the symptomatology of the disease with no specific regard to disease progression or prevention. Herein, we highlight alternative therapeutics for OA specifically considering innovative and encouraging translational methods with the use of adipose mesenchymal stem cells.

Abstract
PURPOSE The aim of this retrospective study was to compare the influence of removing or not removing a prosthesis after regenerative surgery on peri-implant defects. METHODS Two different groups were compared (Group 1: removing the prosthesis; Group 2: maintaining the prosthesis), analyzing radiographic bone filling (n = 32 implants) after regenerative treatment in periapical radiographs. The peri-implant defects were measured before and after regenerative treatment using Bio-Oss® (Geistlich Pharma, Wohhusen, Switzerland) and a reabsorbable collagen membrane (Jason®, Botis, Berlin, Germany), the healing period was two years after peri-implant regenerative surgery. Statistical analysis was performed, and a Chi square test was carried out. To determine the groups that made the difference, corrected standardized Haberman residuals were used, and previously a normality test had been applied; therefore, an ANOVA or Mann-Whitney U test was used for the crossover with the non-normal variables in Group 1 and Group 2. RESULTS The results obtained suggest that a regenerative procedure with xenograft, resorbable membrane, and detoxifying the implant surface with hydrogen peroxide form a reliable technique to achieve medium-term results, obtaining an average bone gain at a radiographic level of 2.84 mm (±1.78 mm) in patients whose prosthesis was not removed after peri-implant bone regenerative therapy and 2.18 mm (±1.41 mm) in patients whose prosthesis was removed during the healing period. CONCLUSIONS There are no statistically significant differences in the response to treatment when removing or keeping the prosthesis after regenerative surgery in peri-implant defects.

Abstract
Erosive lichen planus is an uncommon variant of lichen planus. We report a case of longstanding and refractory plantar ELPs causing disabling and opiate-resistant pain treated with ‘classic’ meshed skin graft combined with Rigenera® micrografts. After approximately 9 months follow-up, no clinical recurrence or pain were observed. Erosive lichen planus (ELP) is an uncommon variant of lichen planus, involving oral cavity and genitalia and, less often plantar areas, where it usually presents with chronic erosions of the soles, along with intense, disabling pain and progressive loss of toenails. An abnormal immune cellular response (CD8+ lymphocytes and macrophages) and the consequent altered production of multiple mediators (interleukin-12, interferon-γ, tumor necrosis factor-α, RANTES and MMP-9), seem to play a crucial role in the pathogenesis, although the etiology remains uncertain. From a histological point of view, ELP shows keratinocyte apoptosis, intense inflammatory response and basal epithelial keratinocytes TNF-α overexpression. Several therapies have been proposed, with variable and controversial results. While topical corticosteroids and topical calcineurin inhibitors are the treatments of choice for localized forms, short pulses of systemic glucocorticoids, phototherapy, and systemic immunosuppressants are recommended for generalized cases. Surgery has been reported as a possible therapeutic option in refractory and stable cases with localized lesions, either alone or with cyclosporine. Herein, we report a case of longstanding and refractory plantar ELPS causing disabling and opiate-resistant pain treated with ‘classic’ meshed skin graft combined with Rigenera® micrografts.

Abstract
The complex tissue engineering/regenerative medicine now represents a therapeutic reality applicable to various organic substrates, with the aim of repairing deficient tissues and restoring normal organ function. Among the possible specialized uses, in the dental field, the treatment of periodontal, pre- and peri-implant bone defects should be mentioned. Nowadays, in oral surgery, there are many surgical methods that can be used, despite that the literature still seems controversial regarding the actual advantages of their use. Surely, this work will bring to light the current clinical-surgical orientations and the different perspectives.

Abstract
Clefts of the lip and/or palate are the most prevalent orofacial birth defects occurring in about 1:700 live human births worldwide. Early postnatal surgical interventions are extensive and staged to bring about optimal growth and fusion of palatal shelves. Severe cleft defects pose a challenge to correct with surgery alone, resulting in complications and sequelae requiring life-long, multidisciplinary care. Advances made in materials science innovation, including scaffold-based delivery systems for precision tissue engineering, now offer new avenues for stimulating bone formation at the site of surgical correction for palatal clefts. In this study, we review the present scientific literature on key developmental events that can go awry in palate development and the common surgical practices and challenges faced in correcting cleft defects. How key osteoinductive pathways implicated in palatogenesis inform the design and optimization of constructs for cleft palate correction is discussed within the context of translation to humans. Finally, we highlight new osteogenic agents and innovative delivery systems with the potential to be adopted in engineering-based therapeutic approaches for the correction of palatal defects. Impact statement Tissue-engineered scaffolds supplemented with osteogenic growth factors have attractive, largely unexplored possibilities to modulate molecular signaling networks relevant to driving palatogenesis in the context of congenital anomalies (e.g., cleft palate). Constructs that address this need may obviate current use of autologous bone grafts, thereby avoiding donor-site morbidity and other regenerative challenges in patients afflicted with palatal clefts. Combinations of biomaterials and drug delivery of diverse regenerative cues and biologics are currently transforming strategies exploited by engineers, scientists, and clinicians for palatal cleft repair.

Abstract
Postmastectomy pain syndrome (PMPS) represents a common complication following breast surgery defined as a chronic neuropathic pain located in the front of the chest, in the axilla and in the upper arm that for more than 3 months after surgery. Several medications prove to be ineffective while autologous fat grafting revealed to be an innovative solution in the treatment of neuropathic pain syndromes based on retrospective studies. For this reason, we performed a prospective multicenter trial to reduce the memory bias and further increase the evidence of the results. From February 2018 to March 2019, 37 female patients aged between 18 and 80 years, underwent mastectomy or quadrantectomy with pathologic scarring and chronic persistent neuropathic pain, compatible with PMPS, are been included in the study and treated with autologous fat grafting. During the enrollment phase, patients were asked to estimate pain using the Visual Analogue Scale (VAS) and POSAS questionnaire in order to evaluate scar outcomes. The VAS scale, starting from 6.9 (1.3), decreased in the first month by 3.10 (1.59), continuing to fall by 0.83 (1.60) to 3 months and by 0.39 (2.09) at 6 months. Statistical analysis showed a significant reduction after 1 month (P < .0001) and 3 months (P < .005). All POSAS grades documented a statistically significant reduction (P < .0001) of the scores by both observers and patients. We observed that no significant association was found between age, BMI, menopausal status of patients, days from oncologic surgery to autologous fat grafting and reduction of VAS values over time while both smoking and axillary dissection were observed as the main factor significantly associated with a reduced clinical efficacy (respectively, P = .0227 and P = .0066). Our prospective multicenter trial confirms the efficacy of fat grafting in the treatment of PMPS based on the principle of regenerative medicine with a satisfactory response in terms of pain reduction and improvement of the quality of the treated tissues. Clinical questionnaires show that the cicatricial areas improve in terms of color, thickness, skin pliability, and surface irregularities. Regenerative effect is based also on the adoption of needles. The combined effect of fat grafting and needles determines a clinical full response.

Abstract
INTRODUCTION The peripheral giant cell granuloma (PGCG) is associated with periodontal bony lesions in several situations and excision results in a soft papilla defect and an intrabony defect without soft tissue protection. CASE PRESENTATION A PGCG associated with loss of periodontal support is described. Following the lesion excision, a specific flap design outlining a surgical papilla in the adjacent area was proposed. The aim of this flap design was to obtain an optimal condition for periodontal regeneration, to treat the lesion excision associated with soft tissue defect, and to avoid a second surgical area. Complete periodontal defect resolution without soft tissue contraction or lesion recurrence was obtained at 2-year follow-up. CONCLUSION Early diagnosis and treatment are essential to prevent greater loss of periodontal attachment.

Abstract
During the last three decades, tissue engineering and reconstructive surgery have become standard therapeutic options in the world of medicine. Several biomaterials, either alone or in combination with cultured cellular products, have been introduced to compensate for the scarcity of autologous donor tissue or to improve healing in a variety of surgical specialties, for example, abdominal/visceral surgery, plastic surgery, and cardiovascular surgery. Many of these biomaterials are of porcine origin. It is well known that Islam has prohibited the consumption of porcine or any of its products. With Muslims accounting for 23% (1.6 billion) of the global population, a thorough review of the implications of porcine-derived tissue-engineered products in surgery seems necessary. In life-threatening conditions as well as severe diseases, the use of porcine-derived products is permissible if similar non-porcine-derived materials are not available. In this case, the use of porcine-derived products represents a necessity and is allowed. Therefore, this distinction between sole need and necessity has great importance not only for the medical community but also for researchers in biotechnology and industry who may consider alternatives to porcine-derived materials.

Abstract
Autologous fat grafting procedures in plastic surgery have been extensively used to reinforce soft tissue in congenital or acquired tissue impairments. With this background, the aim of this study is firstly to examine the impact of a selective centrifugation on existing adipose stem cells (ASCs) in terms of stemness profile maintenance and, secondly, to investigate the effect of restoring volume in reconstruction on patients affected by soft tissue damage. After centrifugation, the fat graft products were separated into two layers and subsequently examined in vitro for the expression of CD34, CD90, CD117, CD105, CD29, CD31, CD44, CD73, CD133, CD14 and CD45 markers by flow cytometry and gene expression analyses were performed for Sox2, WNT3A, END, CD44, FUT4, COLL1, CTNNB1, hbEGF, KRTLG, MMP2 and VIM genes. The results showed that in the middle-high density (MHD) layer there was a peak concentration of ASCs, compared to another layer obtained after centrifugation. Research carried out on patients under treatment for soft tissue regeneration using cells obtained from MHD layer selection will be fundamental in comparative analysis. These studies will lead to an adequate standardization of outcomes, provided that treatment is performed through cell selection. Therefore, a unique procedure in tissue reconstruction and regeneration through fat grafting is presented here.

Abstract
The critical shortage of donor organs has spurred investigation of alternative approaches to either generate replacement organs or implant exogenous cells for treatment of end-stage organ failure. Non-thermal irreversible electroporation (NTIRE), which uses brief high electric field pulses to induce irreversible permeabilization of cell membranes, has emerged as a technique for tumor ablation. Here, we introduce a new application for NTIRE that employs in situ cell ablation to create a niche within a solid organ for engraftment of exogenous cells in vivo. We treated the livers of mice with NTIRE and subsequently implanted exogenous congenic hepatocytes within the zone of cell ablation. Donor hepatocytes engrafted and integrated with host liver parenchyma pre-treated with NTIRE. This new approach should have value for studying the effects of a native matrix scaffold on in vivo cell growth and may pioneer a new type of minimally-invasive regenerative surgery.

Abstract
The graft of autologous fat for the augmentation of soft tissue is a common practice frequently used in the field of plastic and reconstructive surgery. In addition, the presence of adipose derived stem cells (ASCs) in adipose tissue stimulates the regeneration of tissue in which it is applied after the autologous fat grafting improving the final clinical results. Due to these characteristics, there is an increasing interest in the use of ASCs for the treatment of several clinical conditions. As a consequence, the use of clean room environment is required for the production of cell-based therapies. The present study is aimed to describe the biological properties of adipose tissue and cells derived from it cultured in vitro in clean room environment according to current regulation. The collection of adipose tissue was performed using the water-jet assisted liposuction in order to preserve an high cell viability increasing their chances of future use for different clinical application in the field of plastic and reconstructive surgery.

Abstract
BACKGROUND/AIM The aim of the present study was to evaluate the safety and the clinical outcome of platelet-rich plasma for the treatment of teno-desmic injures in competition horses. PATIENTS AND METHODS From January 2009 to December 2011, 150 sport horses suffering from teno-desmic injuries were treated with no-gelled platelet-concentrate. RESULTS No horse showed any major adverse reaction as a result of the procedure. Full healing was obtained for 81% of the horses. Twelve percent had clinical improvement and only 7% a failure. Eight percent of cases of relapse were observed. No statistically significant correlation existed between clinical outcome and the area of the lesion. A statistically significant correlation existed between the clinical outcome and the age of the horse. CONCLUSION Treatment with platelet-derived growth factors leads to the formation of a tendon with normal morphology and functionality, which translate in the resumption of the agonistic activity for the horses we treated.

Abstract
The bone-regenerative potentials of the periosteum have been explored as early as the 17th century. Over the past few years, however, much has been discovered in terms of the molecular and cellular mechanisms that control the periosteal contribution to bone regeneration. Lineage tracing analyses and knock-in transgenic mice have helped define the relative contributions of the periosteum and endosteum to bone regeneration. Additional studies have shed light on the critical roles that BMP, FGF, Hedgehog, Notch, PDGF, Wnt, and inflammation signaling have or may have in periosteal-mediated bone regeneration, fostering the path to novel approaches in bone-regenerative therapy. Thus, by examining the role that each pathway has in periosteal-mediated bone regeneration, in this review we analyze the status of the current research on the regenerative potential of the periosteum. The provided analysis aims to inform both clinician-scientists who may have interest in the current studies about the biology of the periosteum as well as dental surgeons who may find this review useful to perform periosteal-harnessing bone-regenerative procedures.
