Sadeghi S, Ghane Y, Hajizadeh N, Goodarzi A. Autologous adipose tissue injection in the treatment of alopecia: A mini-review. J Cosmet Dermatol 2024; 23:758-765. [PMID: 37955172 DOI: 10.1111/jocd.16081] [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: 09/06/2023] [Revised: 10/07/2023] [Accepted: 10/29/2023] [Indexed: 11/14/2023]
Abstract
BACKGROUND Alopecia may decrease patients' quality of life and self-confidence by limiting their social life. Therefore, the main goal of the treatment is to limit or halt the progression of inflammation, scarring, and hair loss. The promising effect of fat injection on hair regrowth, limited adverse effects, and subsiding inflammation can be proof of its efficacy and safety in treating alopecia. AIMS This review sought to assess the role of autologous fat tissue injection in scarring and non-scarring alopecia. METHODS Accordingly, a thorough search was performed on the Web of Science, Scopus, and PubMed/Medline databases, as well as the Google Scholar search engine, for studies published from inception until September 1st, 2023, using the related keywords. RESULTS Autologous fat grafting (AFG) is a novel and potentially effective modality for treating alopecia, particularly primary and secondary cicatricial alopecia. AFG can be an effective semi-invasive option for treating refractory lichen planopilaris because it induces angiogenesis, which supports hair regrowth. In addition to cicatricial alopecia, AFG held promise for treating non-scarring alopecia, including androgenic alopecia and alopecia areata. The adipose-derived regenerative cells (ADRCs) in adipose tissue (AT) secrete different growth factors, further supporting hair regeneration. Moreover, different anti-inflammatory and anti-oxidative agents are known in AT, preventing further damage to hair follicles. CONCLUSIONS AFG can significantly control inflammatory processes, improve signs and symptoms, and increase hair density and diameter.

Abstract
Systemic sclerosis (SSc) or scleroderma is a rare, systemic, autoimmune connective tissue disease. It causes increased collagen synthesis, leading to multi-organ sclerosis, including the skin and joints. Patients' overall health and quality of life are harmed dramatically. Involvement of the face and, especially, the oral opening can limit patients' ability to speak and eat, oral hygiene, and cosmetic appearance. Profhilo® (NAHYCO®) is an over-the-counter product consisting of pure hyaluronic acid. It is used to improve skin quality by increasing collagen production and adipocyte vitality. This interventional study evaluated the results of perioral injections of hyaluronic acid in terms of improved skin quality, elasticity, and increased oral opening. Patients diagnosed with SSc received an injection of one syringe of Profhilo® (2 mL of hyaluronic acid) at each of two clinic visits at one-month intervals. The oral opening was measured between the upper and lower central incisors before and after treatment. Quality of life was assessed using the modified Rodnan Skin Score and Health Assessment Questionnaire-Disability Index. A total of 14 patients received the first treatment, and 11 received the second treatment. The mean oral opening increased from 31.6 mm (range 17-50 mm) prior to therapy to 35.8 mm (range 21-56) 2 months following the second injection. Statistical analysis showed that there was a significant increase in the oral opening as observed one week (36.2 mm, p = 0.011), one month (36.2 mm, p = 0.007), and three months (31.6 mm, p = 0.023) after the second injection, at the 5-month follow-up. Treatment of SSc patients' perioral area with Profhilo® can result in significant improvements in oral opening and quality of life.

Abstract
BACKGROUND Systemic Sclerosis in the hand is characteristically evidenced by Raynaud's phenomenon, fibrosis of the skin, tendons, ligaments, and joints as well as digital ulcers with prolonged healing. Current medical treatment does not always cure these complications. Local adipose-derived stromal vascular fraction administration into the hands has been proposed as an emerging treatment due to its regenerative properties. The objective of this randomized controlled clinical trial was to evaluate the safety and clinical effects of fat micrografts plus adipose derived-stromal vascular fraction administration into the hands of patients with systemic sclerosis. METHODS This was an open-label, monocentric, randomized controlled study. Twenty patients diagnosed with systemic sclerosis were assigned to the experimental or control group. Fat micrografts plus the adipose derived-stromal vascular fraction were injected into the right hand of experimental group patients. The control group continued to receive only medical treatment. Demographic, serologic data and disease severity were recorded. Digital oximetry, pain, Raynaud phenomenon, digital ulcers number, mobility, thumb opposition, vascular density of the nail bed, skin affection of the hand, serologic antibodies, hand function, and quality of life scores were evaluated in both groups. RESULTS The results of the intervention were analyzed with the Wilcoxon rank test, and the differences between the control and experimental groups at 0 days and 168 days were analyzed with the Mann-Whitney U test. Adverse events were not observed in both groups. At the end of the study, statistically significant improvements were observed in pain levels (p<0.05) and number of digital ulcers (p<0.01) in the experimental vs control group. CONCLUSION The injection of adipose derived-stromal vascular fraction plus fat micrografts is a reproducible, and safe technique. Pain and digital ulcers in the hands of patients with systemic sclerosis can be treated with this technique plus conventional medical treatment.

[PMID: 35130761 PMCID: PMC10233632 DOI: 10.1177/15589447211066347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/17/2022]
Abstract
Autologous fat grafting (AFG) has traditionally been used for facial rejuvenation and soft tissue augmentation, but in recent years, its use has expanded to treat diseases of the hand. Autologous fat grafting is ideal for use in the hand because it is minimally invasive, can restore volume, and has regenerative capabilities. This review summarizes the emerging evidence regarding the safety and efficacy of AFG to the hand in several conditions, including systemic sclerosis, Dupuytren disease, osteoarthritis, burns, and traumatic fingertip injuries. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant literature search on the use of AFG in hand pathologies was performed on October 8, 2020, in Ovid MEDLINE, Elsevier Embase, Clarivate Web of Science, and Wiley Cochrane Central Register of Controlled Trials. The retrieved hits were screened and reviewed by 2 independent reviewers and a third reviewer adjudicated when required. Reviewers identified 919 unique hits. Screening of the abstracts identified 22 manuscripts which described the use of AFG to treat an identified hand condition. Studies suggest AFG in the hands is a safe, noninvasive option for the management of systemic sclerosis, Dupuytren contracture, osteoarthritis, burns, and traumatic fingertip injuries. While AFG is a promising therapeutic option for autoimmune, inflammatory, and fibrotic disease manifestations in the hand, further studies are warranted to understand its efficacy and to establish more robust clinical guidelines. Studies to date show the regenerative, immunomodulatory, and volume-filling properties of AFG that facilitate wound healing and restoration of hand function with limited complications.

Abstract
BACKGROUND Fat grafts are widely used as natural fillers in reconstructive and cosmetic surgery. However, the mechanisms underlying fat graft survival are poorly understood. Here, we performed an unbiased transcriptomic analysis in a mouse fat graft model to determine the molecular mechanism underlying free fat graft survival. METHODS We conducted RNA-sequencing (RNA-seq) analysis in a mouse free subcutaneous fat graft model on days 3 and 7 following grafting (n = 5). High-throughput sequencing was performed on paired-end reads using NovaSeq6000. The calculated transcripts per million (TPM) values were processed for principal component analysis (PCA), unsupervised hierarchically clustered heat map generation, and gene set enrichment analysis. RESULTS PCA and heat map data revealed global differences in the transcriptomes of the fat graft model and the non-grafted control. The top meaningful upregulated gene sets in the fat graft model were related to the epithelial-mesenchymal transition and hypoxia on day 3, and angiogenesis on day 7. Mechanistically, the glycolytic pathway was upregulated in the fat graft model at days 3 (FDR q = 0.012) and 7 (FDR q = 0.084). In subsequent experiments, pharmacological inhibition of the glycolytic pathway in mouse fat grafts with 2-deoxy-D-glucose (2-DG) significantly suppressed fat graft retention rates, both grossly and microscopically (n = 5). CONCLUSIONS Free adipose tissue grafts undergo metabolic reprogramming toward the glycolytic pathway. Future studies should examine whether targeting this pathway can enhance the graft survival rate. DATA AND MATERIALS AVAILABILITY RNA-seq data were deposited in the Gene Expression Omnibus (GEO) database under accession number GSE203599.

Abstract
Systemic sclerosis (SSc) or scleroderma, is a rare, systemic autoimmune connective tissue disease that can cause fibrosis of cutaneous tissue and visceral organs. Facial involvement can have a deleterious effect on patients' function, cosmetic appearance and quality of life. This study describes our experience and results with total facial autologous fat grafting for treating scleroderma. It includes 14 women and 3 men with SSc, at an average age of 51.3 years who underwent 32 autologous fat grafting surgeries between 2017-2022. The surgical technique is further described and demographic and surgical data, including preoperative and postoperative measurements were analyzed. Patients who had multiple surgeries ultimately received grafts with twice the volume of fat than in the first procedure. The oral opening increased an average of 33%. All patients reported improvement in quality of life and were very satisfied with the aesthetic outcomes. The use of autologous fat grafting to treat SSc patients successfully increased oral openings and improved facial manifestations. The procedure is reproducible, safe and leads to improvement in facial manifestations and patients' quality of life. It can be repeated over time to preserve or enhance the results.

Abstract
Systemic sclerosis (SSc) is a heterogeneous, chronic connective tissue disease, characterized by skin fibrosis as well as vascular and visceral lesions. It can involve the lungs, heart, kidneys, gastrointestinal tract, and bones. The orofacial manifestations of SSc can cause functional, aesthetic, and social distress, resulting in significant psychological implications for the patients. In recent decades, fat grafting improved the aesthetic outcomes in terms of volume deficiency, contour asymmetry, and skin elasticity of the face thanks to the regenerative action of the stem cells contained within it. We describe five cases of a patient with SSc treated with fat grafting used to correct volume loss and facial elasticity of the lips and perioral region on the middle and lower third of the face. All the patients received regular postoperative checks at weeks 1 and 2. A multiple choice questionnaire was administered to assess the degree of tolerability of the procedure. The reliability of the questionnaire was evaluated by calculating the Cronbach alpha using the MedCalc Statistical Software version 20.113. The aim of our study is to describe three different types of fat grafting used to correct volume loss and restore facial elasticity of the lips and perioral region on the middle and lower third of the face.

Abstract
Systemic sclerosis is an autoimmune disease featured by uncontrolled fibrosis and collagen deposition. This study aimed to investigate the impact of adipose-derived stem cells (ADSCs) transplantation on collagen in scleroderma. After establishment of scleroderma model using Bleomycin,
the animals received subcutaneous injection of 0.3 ml fat (group B) or 0.3 ml fat+1×106 ADSCs (group C), or 1×106 ADSCs alone (group D). Mice treated with PBS were taken as control group (group A). One month after operation, the skin tissue at injection site
was collected for H&E staining, and immunohistochemistry to determine the content of TGF-β1 and type III collagen. Compared to control group, group B, C, and D exhibited improvement in collagen deposition and reduction in TGF-β1 content and type III collagen. Combined
graft of fat and ADSCs exerted more significant effect compared to single ADSCs treatment. In conclusion, fat and ADSCs transplantation improves collagen deposition in nude mice with scleroderma and the combined treatment exerts a higher efficacy, suggesting that ADSCs need adipose carrier
and microenvironment. These findings provide a novel insight into the treatment of scleroderma.

Abstract
BACKGROUND Scleroderma is a chronic autoimmune disease with an incidence of 2.7 per 100,000 people. Traditional lipotransfer has been used to treat atrophic sclerotic skin. Enzymatically processed cell-assisted lipotransfer (CAL) and mechanically processed stromal vascular fraction gel (SVF-gel) are fat products with abundant adipose-derived stem cells (ASCs). The present study aimed to assess whether ASC-enriched lipotransfer elicits superior therapeutic effects on scleroderma. METHODS Scleroderma was induced in nude mice by injections of bleomycin for 4 weeks. Human-derived Coleman fat (CF), CAL, or SVF-gel (0.1 mL) was injected into sclerotic lesions. Histologic examinations, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL), and expression analyses of inflammatory factors in skin lesions and transferred fat were performed at 4 weeks post-implantation. RESULTS Dermal thickness was lower in the CF- (339.0 ± 19.66 µm), CAL- (271.0 ± 16.15 µm), and SVF-gel- (197.8 ± 12.99 µm) injected groups than in the phosphate-buffered saline-injected group (493.3 ± 28.13 µm) (P<0.05). The numbers of TUNEL+ and Mac2+ cells in fat tissue were significantly higher in the CF-injected group than in the SVF-gel- and CAL-injected groups. Expression of monocyte chemotactic protein-1 and interleukin-6 was significantly lower in the ASC-enriched groups than in the CF group. Histologic analysis showed there were far fewer macrophages and myofibroblasts in skin lesions in the ASC-enriched groups than in the CF group. CONCLUSION Transplantation of SVF-gel and CAL, which contain abundant ASCs, reduces the levels of apoptotic cells and inflammation, significantly reverses skin sclerosis, and elicits superior anti-inflammatory and anti-fibrotic effects on scleroderma.

Abstract
Lichen sclerosus (LS) is a chronic inflammatory dermatosis that mostly affects the genital and anal skin areas. Symptoms may vary from pruritis and pain to sexual dysfunction; however, LS can also be asymptomatic. LS occurs at all ages and in both sexes. Approximately 5% of all women affected by vulvar LS will develop vulvar squamous cell carcinoma. Topical treatment is safe but less effective resulting in chronic course in most patients, who suffer from persistent itching and pain. In severe cases of therapy-resistant LS, there is no adequate treatment. Fat grafting is a novel regenerative therapy to reduce dermal fibrosis. The therapeutic effect of adipose tissue grafts for LS is already investigated in various pioneering studies. This review provides an overview of these studies and the putative mechanisms-of-action of fat grafting to treat LS.

Abstract
Autoimmune thyroid diseases are the most common organ-specific autoimmune diseases, affecting 2–5% of the world’s population. Due to the autoimmune background of thyroid diseases, we analyzed a wide range of cosmetic procedures, from minimally invasive cosmetic injections (mesotherapy) to highly invasive procedures, such as lifting threads. Out of the seven categories of treatments in aesthetic medicine analyzed by us—hyaluronic acid, botulinum toxin, autologous platelet-rich plasma, autologous fat grafting, lifting threads, IPL and laser treatment and mesotherapy—only two, mesotherapy and lifting threads, are not recommended. This is due to the lack of safety studies and the potential possibility of a higher frequency of side effects in patients with autoimmune thyroid diseases.

Abstract
BACKGROUND Most patients with scleroderma suffer from microstomia, which can have debilitating consequences on their quality of life. Unfortunately, treatment options remain limited. No specific guidelines exist; hence, microstomia remains a challenge to treat in this patient population. OBJECTIVE This review aims to evaluate the different medical and surgical treatment modalities currently available for microstomia in patients with scleroderma and make recommendations for future research. MATERIALS AND METHODS A search of PubMed, Ovid MEDLINE, and Ovid Embase was conducted to identify articles discussing the treatment of microstomia in scleroderma. Twenty articles discussing surgical therapy and one article discussing medical therapy were reviewed. RESULTS Mostly because of a scarcity of high-level evidence, no individual therapy has documented long-term efficacy. Some treatments demonstrate positive results and warrant further research. CONCLUSION Given the variability of results, specific recommendations for the treatment of microstomia in patients with scleroderma are difficult to establish. A multifaceted approach that includes surgical and medical therapy is likely the best option to improve oral aperture in this patient population. Surgical treatments such as neurotoxins, autologous fat grafting, and ultraviolet A1 phototherapy may hold the most potential for improvement.

Abstract
Systemic sclerosis (SSc) is an autoimmune disease characterized by significant vascular alterations and multi-organ fibrosis. Microvascular alterations are the first event of SSc and injured endothelial cells (ECs) may transdifferentiate towards myofibroblasts, the cells responsible for fibrosis and collagen deposition. This process is identified as endothelial-to-mesenchymal transition (EndMT), and understanding of its development is pivotal to identify early pathogenetic events and new therapeutic targets for SSc. In this review, we have highlighted the molecular mechanisms of EndMT and summarize the evidence of the role played by EndMT during the development of progressive fibrosis in SSc, also exploring the possible therapeutic role of its inhibition.

Abstract
BACKGROUND Due to the evolving nature of the applications of adipose tissue-derived stem cells (ADSCs) and the rapidly growing body of scientific literature, it is difficult to generate a manual compilation and systematic review of ADSCs in plastic and reconstructive surgery. METHODS Bibliographic records were retrieved from the Web of Science Core Collection and analyzed with CiteSpace. RESULTS We retrieved 691 publications and their references. We identified 52 research categories. Interdisciplinary studies were common. The journals clustered into 13 subnetworks. The top institutions were Stanford University; University of Pittsburgh; University of Tokyo; University of California, Los Angeles; University of California, Davis; New York University; Tulane University; and University of Michigan. National Institutes of Health and National Natural Science Foundation of China provided the most generous financial support. Studies clustered into 22 topics. Emerging trends may include improvement of fat grafting, and application of ADSCs in wound healing, scleroderma, and facial rejuvenation. CONCLUSION The present study provides a panoramic view of ADSCs in plastic and reconstructive surgery. Analysis of journals, institutions, and grants could help researchers in different ways. Researchers may consider the emerging trends when deciding the direction of their study. LEVEL OF EVIDENCE III This journal requires that authors assign a level of evidence to each article.

Abstract
Adipose-derived stem cells (ADSCs) residing in the stromal vascular fraction (SVF) of white adipose tissue are recently emerging as an alternative tool for stem cell-based therapy in systemic sclerosis (SSc), a complex connective tissue disorder affecting the skin and internal organs with fibrotic and vascular lesions. Several preclinical and clinical studies have reported promising therapeutic effects of fat grafting and autologous SVF/ADSC-based local treatment for facial and hand cutaneous manifestations of SSc patients. However, currently available data indicate that ADSCs may represent a double-edged sword in SSc, as they may exhibit a pro-fibrotic and anti-adipogenic phenotype, possibly behaving as an additional pathogenic source of pro-fibrotic myofibroblasts through the adipocyte-to-myofibroblast transition process. Thus, in the perspective of a larger employ of SSc-ADSCs for further therapeutic applications, it is important to definitely unravel whether these cells present a comparable phenotype and similar immunosuppressive, anti-inflammatory, anti-fibrotic and pro-angiogenic properties in respect to healthy ADSCs. In light of the dual role that ADSCs seem to play in SSc, this review will provide a summary of the most recent insights into the preclinical and clinical studies employing SVF and ADSCs for the treatment of the disease and, at the same time, will focus on the main findings highlighting the possible involvement of these stem cells in SSc-related fibrosis pathogenesis.

Fat Grafting Subjectively Improves Facial Skin Elasticity and Hand Function of Scleroderma Patients. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3373. [PMID: 33552819 PMCID: PMC7861649 DOI: 10.1097/gox.0000000000003373] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Accepted: 11/17/2020] [Indexed: 01/15/2023]
Abstract
Systemic scleroderma is a chronic connective tissue disease characterized by internal organ and skin fibrosis. Unfortunately, there is a lack of efficacious treatments for cutaneous manifestations, and alternative interventions should be considered. Fat grafting has gained significant attention due to its regenerative properties and success in improving skin quality and volume deficits in fibrotic diseases. While some studies have investigated the efficacy of autologous fat grafting, we utilized the Coleman method for harvesting and processing to determine the efficacy of fat grafting to improve skin fibrosis in the hands and face of scleroderma patients without excess processing of adipose tissue. Patients with a diagnosis of scleroderma who underwent fat grafting between March 2015 and March 2019 at the University of Michigan were included. Ten female patients were identified that met inclusion criteria. The mean age at the time of surgery was 48.7 (± 17.6) years. An average of 53.2 (± 15.5) ml of fat was injected into the hands and 26.1 (± 16.4) ml into the face. Patients were treated with 1-4 rounds of grafting depending on the initial severity of skin fibrosis and volume deficiency. Fat grafting subjectively and qualitatively improved perioral skin quality, facial animation, hand range of motion, and hand pain for patients with systemic scleroderma. No complications were identified. Additional studies are necessary to determine the ideal volume, timing of treatments, and type of fat to optimize the efficacy of autologous fat grafting for the treatment of systemic scleroderma.

Abstract
BACKGROUND Systemic sclerosis is a connective tissue disease. Skin involvement of the mouth and hand may compromise function and quality of life. Autologous fat grafting has been described as a specific treatment of these clinical features. We report the results of our prospective study designed to treat and prevent skin complications in systemic sclerosis. MATERIALS AND METHODS We treated 25 patients with mouth and/or hand involvement (microstomia, xerostomia, skin sclerosis, Raynaud's phenomenon and long-lasting digital ulcers) with autologous fat grafting, according to the Coleman's technique, around the mouth and/or at the base of each finger. The surgical procedures were repeated in each patient every 6 months for a total of two or three times. Clinical data were collected before the first surgery and again 6 months after each surgical procedure. Pain, skin thickness, saliva production and disability were assessed with validated tests. RESULTS Overall we performed 63 autologous fat grafting sessions (either on the mouth, on the hands or on both anatomical areas). Results at 6 moths after the last session included improvement of xerostomia evaluated with a sialogram, reduction of the skin tension around the mouth and, in the hands, reduction of the Raynaud phenomenon as well as skin thickness. Pain was reduced while the perception of disability improved. Digital ulcers healed completely in 8/9 patients. CONCLUSIONS Our results confirm the efficacy and safety of autologous fat grafting for the treatment of skin complications and digital ulcers due to systemic sclerosis. In addition, the patients' subjective well-being improved. Level of evidence V This journal requires that authors assign a level of evidence to each article.

Abstract
INTRODUCTION Microfat grafting is a well-known technique that is underutilized in dermatology. Instead of removing sclerotic tissue, microfat grafting preserves the tissue and uses stem cells for remodeling its structure into normal tissue. We performed a retrospective study of patients treated with microfat grafting for sclerotic and atrophic skin lesions and scars. PATIENTS AND METHODS Seventy-two microfat grafts were performed using the Magalon technique under general anaesthesia for the treatment of sclerotic and atrophic skin lesions. We performed grafts for different indications, such as scars (n=55) and sclerotic and atrophic skin lesions (n=17: Parry-Romberg syndrome, morphea). The main outcome was assessed for satisfaction during follow-up. In addition, an independent committee judged the results based on photographs. RESULTS Satisfaction levels (e.g. results were judged to be "good") were almost 91% (n=50/55) for scars and 100% (n=17/17) for atrophic and sclerotic skin lesions. Satisfaction levels according to the independent committee were 94.1% for sclerotic and atrophic lesions and nearly 51% for scars. CONCLUSION Satisfaction was high after microfat grafting for atrophic and sclerotic skin lesions. Microfat grafting enabled restoration of the skin texture by exploiting stem cell properties. It is an efficient dermatological therapy for sclerotic and atrophic lesions, for which there are few alternative treatments.

Abstract
Morphea and systemic sclerosis are inflammatory, sclerosing disorders. Morphea primarily affects the dermis and subcutaneous fat, while systemic sclerosis typically involves the skin and internal organs. Functional impairment and cosmetic disfigurement are common in both diseases. Treatment options to mitigate disease progression remain limited. Both functional impairment and cosmetic deficits negatively impact quality of life and psychological well-being in this patient population. While the number of cosmetic procedures performed in the United States continues to rise each year, limited data exist regarding best practices for correcting aesthetic deficits caused by autoimmune conditions. There is scarce information to guide safety decisions regarding laser parameters, soft tissue augmentation, treatment intervals, and the concurrent use of immune-modifying or immune-suppressing medications. Given the fears of disease reactivation and exacerbation from postprocedural inflammation along with limited data, it is difficult for clinicians to provide evidence-based cosmetic treatment with realistic expectations with regard to short- and long-term outcomes. In the first article in this continuing medical education series, we attempt to address this practice gap.

Abstract
BACKGROUND Scleroderma is a chronic connective tissue disease that results in fibrosis of the skin and internal organs. Although internal organ involvement corresponds with poor prognosis, systemic agents are effective at improving the effects of scleroderma on internal organs. In contrast, skin manifestations are universally present in all patients diagnosed with scleroderma, yet no systemic agents have been shown to be successful. Fat grafting has been shown to improve skin quality and improve contour irregularities and may be helpful in the treatment of patients with scleroderma. METHODS The authors performed a thorough review of the pathophysiology of scleroderma and the current treatment options for scleroderma. The efficacy of fat grafting for the treatment of scleroderma and the mechanism by which fat grafting improves outcomes was also discussed. RESULTS Scleroderma is characterized by chronic inflammation and vascular compromise that leads to fibrosis of the skin and internal organs. Fat grafting has recently been the focus of significant basic science research. It has been shown to reduce inflammation, reduce fibrosis by limiting extracellular matrix proteins and increasing collagenase activity, and provide structural support through stem cell proliferation and differentiation. The adipocytes, adipose stem cells, endothelial cells, and vascular smooth muscle cells in the processed fat likely contribute to the effectiveness of this treatment. CONCLUSIONS Fat grafting in scleroderma patients likely improves skin manifestations by recreating fullness, correcting contour deformities, and improving skin quality. The injected fat provides a mixture of cells that influences the recipient site, resulting in improved outcomes.

Abstract
BACKGROUND The authors hypothesize that ischemic preconditioning of the recipient site with deferoxamine will increase fat graft survival by enhancing angiogenesis in a rat model. METHODS Cell viability, tube formation, and mRNA expression were measured in human umbilical vein endothelial cells treated with deferoxamine. A total of 36 rats were then used for an in vivo study. A dose of 100 mg/kg of deferoxamine was injected subcutaneously into the rat scalp every other day for five treatments. On the day after the final injection, the scalp skin was harvested from half the animals to evaluate the effects of deferoxamine on the recipient site. In the remaining animals, inguinal fat tissue was transplanted to the scalp. Eight weeks after transplantation, the grafts were harvested to evaluate the effects of deferoxamine preconditioning on fat graft survival. RESULTS In human umbilical vein endothelial cells, treatment with a deferoxamine concentration higher than 400 μM decreased cell viability compared with the control (p = 0.002). Treatment with 100 and 200 μM deferoxamine increased endothelial tube formation (p = 0.001) and mRNA levels of angiogenesis-related factors (p = 0.02). Rat scalps treated with deferoxamine exhibited increased capillary neoformation (p = 0.001) and vascular endothelial growth factor protein expression (p = 0.024) compared with controls. Fat graft volume retention, capillary density (p < 0.001), and adipocyte viability (p < 0.001) in the grafted fat increased when the recipient site was preconditioned with deferoxamine. CONCLUSION This study demonstrated that recipient site preconditioning with deferoxamine increases fat graft survival by inducing vascular endothelial growth factor and neovascularization.

Abstract
Background Over 90% of patients with systemic sclerosis suffer from gastroesophageal reflux. Esophageal motility disturbances are associated with a reduced life quality and may force interstitial lung disease progression. We wanted to determine whether we can improve gastroesophageal reflux in these patients by esophageal stem-cell injection. Methods We performed a pilot study including eights patients with systemic sclerosis and symptomatic gastroesophageal reflux. Sampling of adipose tissue was performed by an experienced plastic surgeon under local anesthesia. The collected fat was injected into the submucosa of the distal esophagus, each time 1 ml in all four quadrants starting 2, 4 and 6 cm proximal to the Z line (ending up to a total volume of 12 ml). Before the intervention, 3, 6 and finally 12 months after the procedure, patients answered the Gastroesophageal Reflux Disease Health-Related Quality of Life Questionnaire (GERD HRQL) and a high-resolution manometry was performed to quantify changes in motility function. Results All patients showed an improvement in the GERD HRQL score after the stem-cell injection and a lower dosage of proton-pump inhibitors. The manometric findings showed no change throughout the time. A serious adverse event occurred, as one patient developed multiple cerebellar embolic infarcts. Conclusion Because of the favorable effect in all patients, a safe route for esophageal fat injection needs to be developed.

Abstract
BACKGROUND Pedal fat grafting is a cosmetic procedure to treat the functional and aesthetic sequelae of pedal fat pad atrophy. Fat grafting has been found to mitigate these symptoms, but the exact mechanism is unknown. OBJECTIVES The authors hypothesized that pedal fat grafting may improve skin quality, accounting for prolonged symptomatic improvement despite loss of grafted fat. METHODS Patients with pedal atrophy were enrolled in a randomized crossover clinical trial. Group 1 underwent fat grafting upon enrollment with 2-year follow-up. Group 2 was managed conservatively for 1 year then placed into the fat grafting group with 1-year follow-up. Patients underwent pedal ultrasounds to determine thicknesses of the fat pad and dermis, and photographs were taken to assess skin quality. RESULTS Three men and 20 women with an average age of 63 ± 6 years and an average BMI of 26.0 ± 4.6 kg/m2 were enrolled in the study. Twenty-six feet were injected in Group 1 and 17 were injected in Group 2. Group 1 dermal thickness increased at 6 months post-injection (P < 0.05). This increase persisted through 24 months. Group 2 dermal thickness decreased prior to injection (P < 0.05) but returned to baseline after injection and through 12-month follow-up (P < 0.05). Fat pad thickness returned to baseline by study completion in both groups (P < 0.05). CONCLUSIONS Pedal fat grafting yielded a significant, sustained increase in dermal thickness, though grafted fat was not retained. Fat grafting may improve skin quality, which could contribute to improved clinical outcomes despite loss of grafted fat. LEVEL OF EVIDENCE: 2

Abstract
Mesenchymal stromal cells (MSC) are nonhematopoietic cells that can be isolated from several adult and fetal tissues. MSC present specific features as the capacity to support hematopoiesis and to regulate immune response. Thus, the use of MSC as a cell therapeutic product in the field of immune-hematology is of great importance. In this review, we focused on human MSC and discussed their immune-hematologic properties and their translation toward therapeutic clinical applications. Thus, these features hold great promise for cell-based therapy and are of important relevance for the field.

Abstract
BACKGROUND The authors aimed to analyze factors related to lipotransfer for localized scleroderma, and to explore the feasibility of cell-assisted lipotransfer for localized scleroderma treatment. METHODS Abdominal fat samples were taken from six scleroderma patients without corticosteroid therapy, five scleroderma patients with corticosteroid therapy, and 10 normal liposuction patients. Their quantity, morphology, and proliferation ability were measured. Blood flow was measured by laser speckle contrast imaging in localized scleroderma lesions and normal contralateral regions for eight localized scleroderma patients. Bleomycin-induced skin fibrosis nude mice were also used to investigate differences between lipotransfer and cell-assisted lipotransfer. Fat weight was measured, and expression of transforming growth factor (TGF)-β1 and type III collagen in the injected skin was determined by immunohistochemistry. RESULTS The number of stem cells from scleroderma patients with corticosteroid treatment was significantly reduced. Mean blood perfusion in localized scleroderma lesions was not significantly different than in the contralateral normal regions. In normal nude mice, there were no significant changes in TGF-β1 and type III collagen between the control, lipotransfer, and cell-assisted lipotransfer groups, whereas in bleomycin-induced skin fibrosis nude mice, lipotransfer and cell-assisted lipotransfer reduced TGF-β1 and type III collagen expression. CONCLUSIONS For scleroderma patients, fewer adipose-derived stem cells, because of a history of corticosteroid therapy and a local inflammatory microenvironment, are more important factors, whereas blood supply showed no significant change. Therefore, cell-assisted lipotransfer not only improves the survival rate of transplanted fat but also improves skin texture in bleomycin-induced skin fibrosis nude mice.

Abstract
Systemic sclerosis (SSc) is a rare systemic autoimmune disease, characterized by progressive cutaneous and internal organ fibrosis. Orofacial manifestations of systemic sclerosis are extremely disabling and treatment options are limited. In this study, we aimed to assess the safety and efficacy of autologous fat grafting in the face of patients with systemic sclerosis. We enrolled 16 SSc patients suffering from facial sclerosis and limited mouth opening capacity. Autologous fat injection ranging from 15 to 40 ml was administered per patient, based on their face morphology. The patients were evaluated at baseline and 3 months after fat injection. Evaluations included mouth opening capacity, mouth handicap in systemic sclerosis (MHISS), Rodnan skin sclerosis score, skin biophysical properties using a sensitive biometrologic device with the assessment of cutaneous resonance running time (CRRT), volumizing and aesthetic effects based on pre- and posttreatment photographs, possible side effects, and global patient satisfaction. Clinical assessment showed autologous fat transfer significantly improved mouth opening capacity and the MHISS and Rodnan score of patients with facial scleroderma (p value <.001). The aesthetic and/or functional results of fat injection were satisfying to about 80% of the patients. The changes in CRRT values were not significant. Our findings support the possible therapeutic role of autologous fat grafting in improving facial scleroderma both in aesthetic and in functional aspects. This trial is registered with IRCT20180209038677N1.

Abstract
Lumbar laminectomy often results in failed back surgery syndrome. Most scholars support the three-dimensional theory of adhesion: Fibrosis surrounding the epidural tissues is based on the injured sacrospinalis behind, fibrous rings and posterior longitudinal ligaments. Approaches including using the minimally invasive technique, drugs, biomaterial and nonbiomaterial barriers to prevent the postoperative epidural adhesion were intensively investigated. Nevertheless, the results are far from satisfactory. Our review is based on various implant biomaterials that are used in clinical applications or are under study. We show the advantages and disadvantages of each method. The summary will help us to figure out ideas towards new techniques. The translational potential of this article: This review summarises recent biomaterials-related clinical and basic research that focuses on prevention of epidural adhesion after lumbar laminectomy. We also propose a novel possible translational method where a soft scaffold acts as a physical barrier in the early stage, engineered adipose tissue acts as a biobarrier in the later stage in the application of biomaterials and adipose-derived mesenchymal stem cells are used for prevention of epidural adhesion.

Abstract
INTRODUCTION Adipose grafting has undergone significant changes over time. Many different techniques have been followed by trying to improve the quality of the lipoaspirate and the survival of the fat graft after implantation. MATERIAL AND METHODS The purpose of this review is to analyse the historical evolution of the surgical harvesting and implant technique, describing the changes that have brought significant improvements, revolutionizing the aesthetic and functional results obtainable. RESULTS A standard fat grafting technique is commonly performed in three stages: harvesting of adipose tissue from a suitable donor site; processing of the lipoaspirate to eliminate cellular debris, acellular oil and excess of infiltrated solution, reinjection of the purified adipose tissue. The most widely used surgical technique was described by Coleman. He modified and corrected the methods and results of his predecessors and proposed an atraumatic protocol for the treatment of adipose tissue.He reported that the key to successful fat grafting lies in the technique. In addition, he noticed that adipose tissue was not only a good filler, but improved the quality of the skin. In fact, fat grafts demonstrated to have not only dermal filler properties but also regenerative potential owing to the presence of stem cells in fat tissue. CONCLUSION Adipose tissue, actually, is the closest to the ideal filler because it is readily available; easily obtainable, with low donor-site morbidity; repeatable; inexpensive; versatile; and biocompatible. There is an abundance of literature supporting the efficacy of fat grafting in both aesthetic and reconstructive cases. Recent studies have shown the utility of adipose-derived stem cells in the improvement of wound healing, describing their ability to regenerate soft tissues and their remodelling capacity provided by their unique cytokine and growth factor profiles.Despite ongoing concerns about survival and longevity of fat grafts after implantation and unpredictability of long-term outcome, fat has been successfully used as a filler in many differ clinic situation.

Abstract
Background The use of stem cells, including mesenchymal stem cells (MSCs), for regenerative medicine is gaining interest for the clinical benefits so far obtained in patients. This study investigates the use of adipose autologous tissue in combination with platelet-rich plasma (PRP) to improve the clinical outcome of patients affected by systemic sclerosis (SSc). Methods Adipose-derived mesenchymal stem cells (AD-MSCs) and PRPs were purified from healthy donors and SSc patients. The multilineage differentiation potential of AD-MSCs and their genotypic–phenotypic features were investigated. A cytokine production profile was evaluated on AD-MSCs and PRPs from both healthy subjects and SSc patients. The adipose tissue-derived cell fraction, the so-called stromal vascular fraction (SVF), was coinjected with PRP in the perioral area of SSc patients. Results Histopathological and phenotypical analysis of adipose tissue from SSc patients revealed a disorganization of its distinct architecture coupled with an altered cell composition. Although AD-MSCs derived from SSc patients showed high multipotency, they failed to sustain a terminally differentiated progeny. Furthermore, SVFs derived from SSc patients differed from healthy donors in their MSC-like traits coupled with an aberrant cytokine production profile. Finally, the administration of PRP in combination with autologous SVF improved buccal’s rhyme, skin elasticity and vascularization for all of the SSc patients enrolled in this study. Conclusions This innovative regenerative therapy could be exploited for the treatment of chronic connective tissue diseases, including SSc.

Abstract
In the past decade, adipose tissue has become a highly interesting source of adult stem cells for plastic surgery and regenerative medicine. The adipose source offers two options for the isolation of regenerative cells: the enzymatic digestion an expensive time-consuming procedure lacking a common standard operating protocol, or the non-enzymatic dissociation methods based on mechanical forces to break the processed adipose tissue. Here, we propose innovative inexpensive non-enzymatic protocols to collect and concentrate clinically useful regenerative cells from adipose tissue by centrifugation of the infranatant fraction of lipoaspirate as first step, usually discarded as a byproduct of the surgical procedure, and by fat shaking and wash as second enrichment step. The isolated cells were characterized according to the criteria proposed by the Mesenchymal and Tissue Stem Cell Committee of the International Society for Cellular Therapy (ISCT) to define human mesenchymal stem cells, and the results were compared with matched lipoaspirate samples processed with collagenase. The results demonstrated the usability of these new procedures as an alternative to fat grafting for treating stem cell-depleted tissues and for specific application requiring minimal or null soft tissue augmentation, such as skin diseases including severe burn and post-oncological scaring, chronic non-healing wounds, and vitiligo.

Abstract
BACKGROUND Systemic sclerosis (SSc) is an autoimmune disease with multisystem involvement, dominated by a general fibrosis. The early stage of the disease is associated with progressive damage to microcirculation, particularly in the respiratory tract, the gastrointestinal tract and skin. The face assumes a typical appearance characterized by microstomia (reduction of mouth opening) and microcheilia (thinning of the lips). These conditions cause a considerable reduction in performance status of patients. We treated them by fat grafting, rich in adipose stem cells, and we evaluated through time clinical, functional and aesthetic evaluation of oral pathology associated with SSc. MATERIALS AND METHOD From September 2014 to May 2016, we enrolled and treated seven patients in the plastic, reconstructive and aesthetic surgery clinic. Through time, we evaluated the following parameters: evaluation of mouth opening (maximum opening in superior-inferior and lateral directions) and lip thicknesses, both measured by doctors of the aforementioned operating unit; variation in the quality of life as perceived by patients according to the MHISS scale (Mouth Handicap Systemic Sclerosis); variation in severity of labial fibrosis assessed by microscopic analysis of pre- and post-fat transfer samples in the pathology clinic; safety of the protocol, according to the management of side effects resulting from the procedure; aesthetic evaluation, made by external observers and non-experts in the field, on pre- and post-operative photographs. RESULTS AND CONCLUSIONS We reported satisfying results, both functionally and aesthetically, for all parameters except one, for which the sample size might have proven critical. These data should be a starting point for further experimental research and clinical trials. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article.

Abstract
Lipotransfer for soft tissue filling is a well-established plastic and aesthetic surgical technique. Elective fat grafting is considered a safe and well-tolerated procedure. Coleman and others have reported that fat grafting may have tissue regenerative properties and not only serve as a soft tissue filler. There have been reports from our group and others that it may improve fibrosis secondary to many different pathological aetiologies including scleroderma, burn injury, lichen sclerosis, graft vs host disease, and radiation. The mechanism of action remains unclear but has been postulated that is adipose derived stem cells (ADSCs) related. Lipoaspirate has been characterised and shown to contain several cell populations including fibroblasts, endothelial cells, and ADSCs. The ADSCs have shown to secrete angiogenic, immunodulatory, and antiapoptotic factors as well as proliferate and differentiate into different cell types similarly to other stem cell sources. We have shown that ADSCs are functionally different in scleroderma patients but despite this lipotransfer produces a significant reversal in the effects of fibrosis in these patients. The advantage of lipoaspirate containing a valuable source of regenerative properties, ease of access, isolation, and processing may serve a significant future role in the treatment of fibrotic conditions.

Abstract
Zuk et al in 2001 identified stem and regenerative cells within the stromal vascular fraction of fat. In preclinical studies, these cells appeared to stimulate angiogenesis and reduce inflammation, and soon thereafter, clinical use of stromal vascular fraction (SVF) evolved as researchers such as Rigotti, Coleman, Mojallal, our group, and others demonstrated that fat can be used for both therapeutic and aesthetic indications. The regenerative effects of fat and its contents on facial aesthetics have been shown at the histologic and cellular level. Regeneration of elastin and collagen fibers as well as improvement in capillary density and reduction of inflammation have been reported. We review our current approach to the use of regenerative cells and different types of fat grafts in facial surgery. The fat graft is classified, both from a regenerative point of view as well as a tissue product that can be modified into different tissue characteristics, depending on the area and condition treated. Clinical use of SVF enriched fat, millifat, microfat, and nanofat grafts as well as composite fat grafts are reviewed. Based on clinical experience and evidence to date, it appears that the regenerative effects seen with the use of SVF in aesthetic surgery are modest, but there appear to be definite histologic findings of regeneration. These improvements may not be clinically apparent to a patient when cell enriched fat grafts are compared to fat grafts alone. However, the subtle changes seen in histology may be cumulative over time. Three types of fat grafts are defined: millifat (parcel size 2.4<), microfat (1.2<), and nanofat (400-600 μm). Each are characterized by their injectability ratings and emulsification parcel size as well as amount of sSVF cells. Newer concepts of periosteal fat grafting, buccal fat pad grafting, pyriform aperture fat grafting, intraorbital fat grafting, and nanofat grafting are discussed. Composite fat grafts are presented as a new concept as is biofilling and biocontouring. The use of regenerative cells in facial surgery is evolving rapidly. Our understanding of the anatomic changes that occur with aging has become more precise and our ability to target histologic changes seen with aging has become more effective. Deep fat compartment grafting, superficial fat grafting, nanofat, and SVF are becoming important components of contemporary facial rejuvenation. The use of regenerative approaches in facial rejuvenation is a logical step in changing the paradigm from surgical treatment of aging to a more proactive prevention and maintenance approach that keeps up with changes in the tissues as they age.

Abstract
Lipomodeling is the process of relocating autologous fat to change the shape, volume, consistency, and profile of tissues, with the aim of reconstructing, rejuvenating, and regenerating body features. There have been several important advancements in lipomodeling procedures during the last thirty years. Four clinical steps are important for the success of engraftment: fat harvesting, fat processing, fat reinjection, and preconditioning of the recipient site. With the discovery of adipose derived stem cells and dedifferentiated cells, fat cells become a major tool of regenerative medicine. This article reviews recent trends in lipomodeling trying to understand most of the issues in this field.

Abstract
Objective: The use of noncultured autologous stromal vascular fraction or clinical grade adipose-derived regenerative cells (ADRCs) is a promising strategy to promote wound healing and tissue repair. Nevertheless, issues regarding the optimal mode of administration remain unclear. The purpose of this study was to compare the effects of local injection and topical spray delivery of ADRCs in a porcine model of thermal burns. Approach: Full-thickness thermal burns were created on the dorsum of 10 Gottingen minipigs. Two days following injury, wounds underwent fascial excision and were randomized to receive control vehicle or freshly isolated autologous ADRCs delivered by either multiple injections into or surrounding the wound bed, or by spray onto the wound surface (0.25 × 106 viable cells/cm2). Healing was evaluated by planimetry, histopathology, and immunohistochemistry at day 7, 12, 16, 21, and 28 posttreatment. Results:In vitro analysis demonstrated that there was no substantial loss of cell number or viability attributable to the spray procedure. Planimetric assessment revealed that delivery of ADRCs by either local injection or topical spray increased wound reepithelialization relative to control at day 14. No significant difference in wound reepithelialization was observed between both delivery approaches. In addition, on day 7 posttreatment, blood vessel density was greater in wounds receiving local or topical spray ADRCs than in the wounds treated with vehicle control. Histopathologic analysis suggests that ADRC treatment may modulate the inflammatory response by reducing neutrophil infiltration at day 7 and 12 posttreatment, irrespective of the route of administration. Conclusions: These data demonstrate that local injection and spray delivery of ADRCs modulate inflammation and improve wound angiogenesis and epithelialization. Importantly, both delivery routes exhibited similar effects on wound healing. Given the greater ease-of-use associated with topical spray delivery, these data support the use of a spray system for autologous ADRC delivery.
