Abstract
Adipose tissue resorption after fat grafting is a major drawback in plastic and reconstructive surgery, which is primarily caused by the insufficient blood perfusion of the grafts in the initial phase after transplantation. To overcome this problem, several promising strategies to boost the vascularization and, thus, increase survival rates of fat grafts have been developed in preclinical studies in recent years. These include the angiogenic stimulation of the grafts by growth factors and botulinum neurotoxin A, biologically active gels, and cellular enrichment, as well as the physical and pharmacological stimulation of the transplantation site. To transfer these approaches into future clinical practice, it will be necessary to establish standardized procedures for their safe application in humans. If this succeeds, the surgical outcomes of fat grafting may be markedly improved, resulting in a significant reduction of the physical and psychological stress for the patients.

Abstract
Autologous fat transplantation -i.e., lipofilling- has become a promising and popular technique in aesthetic and reconstructive surgery with several application such as breast reconstruction, facial and hand rejuvenation. However, the use of this technology is still limited due to an unpredictable and low graft survival rate (which ranges from 25%-80%). A systematic literature review was performed by thoroughly searching 12 terms using the PubMed database. The objective of this study is to present the current evidence for the efficacy of adjuvant regenerative strategies and cellular factors, which have been tested to improve fat graft retention. We present the main results (fat retention rate, histological analysis for pre-clinical studies and satisfaction/ complication for clinical studies) obtained from the studies of the three main fat grafting enrichment techniques: platelet-rich plasma (PRP), the stromal vascular fraction (SVF) and adipose-derived stem cells (ADSCs) and discuss the promising role of recent angiogenic cell enrichment that could induce early vascularization of fat graft. All in all, adding stem or progenitor cells to autologous fat transplantation might become a new concept in lipofilling. New preclinical models should be used to find mechanisms able to increase fat retention, assure safety and transfer these technologies to a good manufacturing practice (GMP) compliant facility, to manufacture an advanced therapy medicinal product (ATMP).

Abstract
BACKGROUND This review was designed to discuss the safety and efficacy of using platelet-rich fibrin (PRF) in fat grafts during facial lipostructure. METHODS From January 2018 to December 2021, 650 fat grafts for facial lipostructure were performed in the authors' department. According to their wishes, we divided the patients into two groups: 498 patients were treated with autologous fat injection (control group), and 152 patients were treated with autologous fat injection combined with PRF. All of the patients were monitored for at least six months. The effects were evaluated via physician assessment and patient satisfaction rates, and the incidences of complications were compared. RESULTS All the cases had a degree of improvement after treatment. The patient satisfaction rate was 55.3% in the PRF group and 43.4% in the control group. In all, 68.4% of the patients in the PRF group and 58.2% in the control group indicated that one-stage surgery was sufficient to achieve the desired effect. According to the evaluation conducted by the plastic surgeon, 59.2% of patients in the PRF group and 47.0% in the control group achieved a perfect effect. A total of 76.3% of patients in the PRF group and 63.9% in the control group reported that one surgery achieved satisfactory results. The difference between the PRF and control groups was statistically significant. CONCLUSION Using an autologous fat graft during facial lipostructure is beneficial and safe when combined with PRF. The combination may enhance the effect and satisfaction rate. Further research and prospective clinical studies are needed to understand the role of PRF in fat grafting.

Abstract
Stem cells could form the basis of a novel, autologous treatment for chronic wounds like diabetic foot ulcers. Fat grafts contain adipose-derived stem cells (ADSC) but low survival of cells within the grafts is a major limitation. Platelet-rich plasma (PRP) may increase graft survival. This review examines the histology from animal studies on fat grafting, ADSC and PRP in wound healing. A literature review of major electronic databases was undertaken, and narrative synthesis performed. Data from 30 animal studies were included. ADSC increase angiogenesis over 14 days and often clinically accelerated wound healing. ADSC had a greater effect in animals with impaired wound healing (e.g. diabetes). Activated PRP increased viability of fat grafts. Despite the high number of studies, the quality is variable which weakens the evidence. It does suggest there is a benefit of ADSC, particularly in impaired wound healing. High-quality evidence in humans is required, to establish its clinical usefulness.

Abstract
BACKGROUND Genitourinary syndrome of menopause (GSM) is a major problem in many post- or perimenopausal women. Lipofilling has long been considered to be an effective technique for restoring volume, but the discovery of its trophic proprieties has made it the most widely utilized method in regenerative medicine. OBJECTIVES The authors aimed to assess the safety and efficacy of microfat and nanofat grafting for vulvovaginal rejuvenation. METHODS Women with GSM who met the inclusion criteria were enrolled. Women received microfat in the labia majora and nanofat in the vagina; follow-up was conducted 1, 3, 6, 12, and 18 months. The vaginal health index (VHI) and Female Sexual Distress (FSD) were utilized to assess improvement in vulvovaginal atrophy, orgasm, and sexual desire posttreatment. RESULTS Fifty women were included; their average age was 53 years (range, 45-63 years). The VHI score significantly increased at 1 and 3 months after treatment (P < 0.0001). Moreover, the average FSD score showed a significant improvement at 1 and 3 months posttreatment. This score stabilized from 6 to 12 months but showed further improvement at 18 months. At 6 months posttreatment, for both scales, data pertaining to 80% of patients appeared normalized. There was a particular benefit noted for dryness and dyspareunia. At 18 months, the results remained stable for all of patients. No major side effects were observed. CONCLUSIONS There are now many ways to rejuvenate the intimate sphere, but microfat and nanofat grafting seem to offer good results with an autologous procedure. Their utilization appears promising for genital rejuvenation. LEVEL OF EVIDENCE: 4

Abstract
Diabetic foot ulcers are often unresponsive to conventional therapy and are a leading cause of amputation. Animal studies have shown stem cells and growth factors can accelerate wound healing. Adipose‐derived stem cells are found in fat grafts and mixing them with platelet‐rich plasma (PRP) may improve graft survival. This study aimed to establish the histological changes when diabetic foot ulcers are treated with fat grafts and PRP. A three‐armed RCT was undertaken of 18 diabetic foot ulcer patients: fat grafting; fat grafting with PRP; and routine podiatry care. Biopsies were obtained at week 0, 1, and 4, and underwent quantitative histology/immunohistochemistry (H&E, CD31, and Ki67). Treatment with fat and PRP increased mean microvessel density at 1 week to 1645 (SD 96) microvessels/mm2 (+32%‐45% to other arms, P = .035). PRP appeared to increase vascularity surrounding fat grafts, and histology suggested PRP may enhance fat graft survival. There was no clinical difference between arms. This study demonstrates PRP with fat grafts increased neovascularisation and graft survival in diabetic foot ulcers. The histology was not, however, correlated with wound healing time. Future studies should consider using apoptosis markers and fluorescent labelling to ascertain if enhanced fat graft survival is due to proliferation or reduced apoptosis. Trial registration NCT03085550.

Abstract
Autologous fat grafting has been widely used for soft tissue filling in plastic surgery. Platelet-rich plasma (PRP) could play a wide role in health and disease because of containing a variety of growth factors and cytokines. Although previous studies have described the positive effect of autologous PRP mixed with fat grafts, only minimal improvements in fat graft survival have been reported. The present study is aimed at comparing the effects of PRP and platelet-poor plasma (PPP) on the survival and quality of fat grafting. We built a 180-day nude mouse model implanted with a fat graft supplemented with PRP, PPP, or saline, respectively. The above reagents (PRP, PPP, or saline) were injected two additional times after the initial engraftment. The survival ratio of the fat grafts and the capillary density in the PRP group were significantly higher than those in the PPP group and the saline group (control group) at 15, 30, 90, and 180 days posttransplantation (P < 0.05). The survival ratio of the PPP group was higher than that of the saline group (P < 0.05), but the capillary density in the PPP group was not significantly different from that in the saline group at any time point (P > 0.05). We hence conclude that the repeated application of PRP or PPP three times can enhance the survival of fat grafts within 180 days. Moreover, the effect of PRP is superior to that of PPP.

Abstract
Autologous fat grafting is increasingly being used as a method for the repair of facial soft tissue defects and facial rejuvenation, given its low risk of adverse effects and high efficacy. However, the unpredictability of graft retention is a limitation of this procedure. In addition, there is no standard procedure to date for autologous fat grafting. Different methods have been developed to increase the retention of grafted fat. For instance, platelet concentrates have been used to directly deliver bioactive factors to grafted fat. Platelet concentrates also provide incidental therapeutic benefits by enhancing the persistence of fat grafted in the face via the release of growth factors and cytokines. In this review, we describe current strategies for improving the survival of facial fat grafts, mainly focusing on the application of growth factors/cytokines and platelet concentrates to fat grafting.

Abstract
Fat grafting is becoming a common procedure in regenerative medicine because of its high content of growth factors and adipose derived stem cells (ADSCs) and the ease of harvest, safety, and low cost. The high concentration of ADSCs found in fat has the potential to differentiate into a wide range of wound-healing cells including fibroblasts and keratinocytes as well as demonstrating proangiogenic qualities. This suggests that fat could play an important role in wound healing. However retention rates of fat grafts are highly variable due in part to inconsistent vascularisation of the transplanted fat. Furthermore, conditions such as diabetes, which have a high prevalence of chronic wounds, reduce the potency and regenerative potential of ADSCs. Platelet-rich plasma (PRP) is an autologous blood product rich in growth factors, cell adhesion molecules, and cytokines. It has been hypothesised that PRP may have a positive effect on the survival and retention of fat grafts because of improved proliferation and differentiations of ADSCs, reduced inflammation, and improved vascularisation. There is also increasing interest in a possible synergistic effect that PRP may have on the healing potential of fat, although the evidence for this is very limited. In this review, we evaluate the evidence in both in vitro and animal studies on the mechanistic relationship between fat and PRP and how this translates to a benefit in wound healing. We also discuss future directions for both research and clinical practice on how to enhance the regenerative potential of the combination of PRP and fat.

Abstract
In 2009, the American Society of Plastic Surgeons Task Force on Autologous Fat Grafting (AFG) determined that autologous fat grafting was a safe procedure with a relatively low rate of complications. This consensus opinion unleashed a wave of popularity as plastic surgeons discovered the procedures' efficacy in a wide variety of cosmetic and reconstructive indications. Frequently reported cosmetic applications include soft-tissue augmentation of breast, buttocks, hips, face, and hands, whereas reconstructive applications include adjunct for breast reconstruction contour problems, plantar fat pad improvement, and correction of various posttraumatic and surgical contour deformities. Recognition of other regenerative effects of fat grafting expanded the use AFG for improvement of hypertrophic scar tissue, postradiation sequelae, lipodystrophy, hyperpigmentation, senile skin changes, and actinic damage. The popularity of AFG is supported by a remarkably low risk of complications, minimal scars, and readily available donor sites. Despite recognition of the advantages of AFG, there still is no consensus regarding optimal techniques of harvest, graft preparation, and injection. Further, the yield of permanent volume falls within a very wide range. In this article, we review the basic science of fat grafting, proposed methods offered to improve engraftment, and reported outcomes of AFG procedures.

Abstract
Adipose-derived stem cells found in fat grafts may have significant healing properties. When fat is combined with autologous platelet-rich plasma (PRP), there may be enhanced healing effects due to the pro-angiogenic and anti-inflammatory effects of PRP. This study aimed to evaluate the current evidence on fat grafting in combination with PRP for wound healing to establish the efficacy of this technique. A comprehensive search in the MEDLINE, EMBASE, CENTRAL, Science Citation Index, and Google Scholar databases (to March 2017) was conducted to identify studies on fat grafting and PRP for wound healing. Case series of less than 3 cases and studies only describing harvest technique were excluded. The database identified 571 articles, of which 3 articles that used a combination of fat and PRP for wound healing (1 RCT and 2 case series) were included in this review. A total of 69 wounds in 64 patients were treated with an average wound size of 36.32cm2 . Of these, 67% of wounds achieved complete healing. When reported, the mean time to healing was 7.5 weeks for those who underwent a single treatment. There were no significant complications in any patients. The combination of fat grafting and PRP may achieve adequate wound healing with relatively quick wound healing time compared with standard wound management options. However, evidence is extremely limited, and further studies are required to evaluate its efficacy for wound healing.

Abstract
BACKGROUND The adjunction of platelet-rich plasma with graft fat has been the subject of a few clinical trials which have demonstrated its value in adipocyte survival. The aim of this study was to assess the different efficacies between activated and non-activated PRP on adipose cells in vitro and for adipose tissue graft survival in vivo. METHODS The in vitro study assessed the effects of PRP on both the proliferation and adipocyte differentiation of adipose cells. For the in vivo study, 8 nude rats received 3 human fat injections as follows: 0.8 mL of fat + 0.2 mL of normal saline; 0.8 mL of fat + 0.2 mL of non-activated PRP; and 0.8 mL of fat + 0.2 mL of PRP activated with calcium chloride (CaCl2). The quantitative assessment of adipocyte survival was implemented after 3 months using histomorphometric analysis. Histological and immunohistochemical analysis were also performed to evaluate angiogenesis, inflammation and quality of adipocytes in the grafted tissue. RESULTS We showed that activated PRP stimulated, in vitro, proliferation and differentiation of adipose cells. In vivo experiments indicated that CaCl2-activated PRP was more efficient than non-activated to prolong the survival of fat grafts in nude rats. The mean percentage areas occupied by viable adipocytes in the PRP-free group, non-activated PRP group and activated PRP group were 13%, 14% and 24% (p = 0.05%), respectively. Histological and immunohistochemical analysis revealed protective effect of activated PRP on inflammation and adipocyte death. CONCLUSION This study showed that activation by CaCl2 improves the beneficial effects of PRP for fat graft maintenance.

Abstract
Purpose: Peridural fibrosis which could occur after the spinal surgery could adhere neural tissue closely and may cause to neural entrapment symptoms and require surgical reintervention. Aim of the study: Present study was designed to reduce occurrence of peridural fibrosis in rat laminectomy model by using biophysical barriers called hyaluronic acid (HAS) dural barrier, activated polyethylene glycol and polyethylene imine (PEG) dural barrier, and platelet-rich plasma (PRP). Materials and methods: In this study, 2 of 26 male Wistar albino rats (325-350 g body weight), which were not included into study groups were sacrificed by removing their total blood and their blood was used for preparation of PRP, and remaining rats were randomly delivered into four groups called SHAM, HAS, PEG, and PRP groups. Then L3-4-5 laminectomy was performed to all animals and experimental agents were administered to the selected groups mentioned above. Spinal colons of all animals were removed gross total after 6-week period and investigated histopathologically. Additionally, real-time-polymerase chain reaction was used to obtain collagen type I and type III, transforming growth factor-1β, and tumor necrosis factor-α gene expressions. Results: All results demonstrated that polyethylene glycol and polyethylene imine dural barrier and PRP could decrease peridural fibrosis formation efficiently in rat. Conclusion: Present study results suggested that to reduce or block formation of peridural fibrosis, either polyethylene glycol and polyethylene imine dural barrier or PRP could be used effectively in human subjects after they will be closely investigated in future studies.

Abstract
BACKGROUND The addition of platelet-rich plasma (PRP) to adipose tissue may improve fat graft survival, although graft retention rates vary markedly between studies. To what extent this outcome heterogeneity reflects differing methodological factors remains unknown. This systematic review aims to synthesize and critically review methodological approaches to autologous PRP and fat cotransplantation in both human and animal studies. METHODS In accordance with PRISMA guidelines, Ovid MEDLINE, Scopus, and Cochrane Library databases were searched from inception to April 2017. Data were extracted from all in vivo studies involving autologous PRP and fat cotransplantation. A secondary aim was to assess reporting of technical detail; authors were not contacted to provide missing data. RESULTS From 335 articles, 23 studies were included in the qualitative synthesis. Some 21 were performed in humans and 2 in rabbits. Six studies were randomized control trials; the remainder reported on observational data. Methods of PRP extraction and activation varied markedly between studies. Fat graft preparation was comparatively more consistent. Methods of PRP and fat mixing differed significantly, especially with regards to relative volume/volume ratios. CONCLUSIONS Our study represents the first systematic review of methodological factors in autologous PRP and fat cotransplantation. It demonstrates that technical factors in graft preparation and administration vary significantly between in vivo studies. Such methodological heterogeneity may explain observed differences in experimental and clinical outcomes. Reporting of key procedural information is inconsistent and often inadequate. These issues make meaningful evaluation of the PRP-enhanced fat grafting literature difficult and may limit its translation into clinical practice.

Abstract
Fat grafting has emerged as an important tool in the armamentarium of plastic surgeons. Its applications in aesthetic and reconstructive surgery continue to expand. However, its limitations (such as inconsistent survival) remain problematic. Recent research efforts have focused on tacking these issues with the use of platelet rich plasma, hypoxic preconditioning, hyperbaric oxygen, and the tissue engineering of scaffolds. In the future, as these laboratory discoveries are translated to clinical application, the beneficial uses of fat grafting will continue to increase.

Abstract
The goal of adding platelet-rich plasma (PRP) to autologous fat graft is to increase the survival rate of the graft. After their activation, platelets release some important growth factors. As a result, PRP may increase the proliferation and differentiation of Adipose-derived stem cells (ASCs) into adipocytes, improve fat graft vascularisation, and may block the apoptosis of grafted adipocytes. The other benefit expected from the addition of PRP to fat graft is the improvement of cutaneous trophicity above the grafted areas. An exhaustive review of the literature retrieved 11 clinical studies on humans and 7 on animals. A statistically significant increase of the survival rate of fat grafts has been found in 9 comparative studies. Our synthesis allowed us to set up the following protocol: addition of 20% of PRP activated with calcium hydrochloride to fat grafts. It may enhance the results of autologous facial fat graft in regenerative and aesthetic facial surgery.

Abstract
PURPOSE: To investigate if the association of fat grafts and platelet-rich plasma (PRP) improves graft viability in female rats. METHODS: This is an experimental, randomized and blinded study, which involved 47 rats. Fat was harvested from the inguinal region and grafted to the cranial region. The experimental group consisted of PRP-enriched fat grafts (n=22) whilst the control group consisted of fat graft only (n=25). After a 100-day period, the animals were euthanised and the fat grafts were analyzed using scores from 0 (absent) to 4 (abundant), in optical microscopy by two independent and blinded pathologists. RESULTS: Regarding fat graft cell viability, the PRP group scored moderate/abundant in 63% of cases and the fat graft only group scored absent/slight in 72% of cases (p=0.03). The PRP group also presented lower fat necrosis scores when compared to the fat graft only group (p=0.03). Tumors (dermoid cysts) within the fat grafts were observed in three animals in which the grafts were mixed with PRP. CONCLUSION: Platelet-rich plasma improves the viability and integration of fat grafts in rats, but more studies are needed to fully understand the exact mechanisms that lead to this improvement and assess the safety of the method for use in humans.

Abstract
BACKGROUND Platelet-rich plasma (PRP) contains multiple growth factors and has been shown to enhance fat graft survival after lipotransfer. However, the molecular mechanisms mediating this effect remain unknown. Adipose-derived stem cells (ASCs) play an important role in fat graft survival and are a likely target for PRP-mediated effects. This study seeks to investigate the impact of PRP on ASC proliferation and adipogenic differentiation. METHODS Human ASCs were isolated using our laboratory protocol. The experiments were divided into four arms: (1) ASCs cultured in general culture medium alone; (2) ASCs in general culture medium + 5%, 10%, 15%, or 20% PRP; (3) ASCs cultured in adipogenic differentiation medium alone; (4) ASCs cultured in adipogenic medium + 5%, 10%, 15%, or 20% PRP. Cell proliferation was analyzed and comparative m-RNA expression of adipogenic genes was assessed by quantitative PCR. Protein expression was determined by western blot. RESULTS PRP significantly enhanced proliferation of ASCs, even in the presence of antiproliferative, proadipogenic media. In contrast, PRP inhibited adipogenic differentiation in adipogenic media, evidenced by decreased intracellular lipid accumulation and reduced adipogenic gene expression (PPAR-γ and FABP4). Inhibition appears to occur through downregulation of bone morphogenetic protein receptor IA (BMPRIA) and fibroblast growth factor receptor 1 (FGFR1). Interestingly, PRP elicited these effects across the entire range of doses studied. CONCLUSIONS PRP appears to modulate ASC function primarily by enhancing cell proliferation. The consequences of its impact on adipogenesis are less clear. Enhanced proliferation initially might set the stage for more robust regeneration and adipogenesis at later time points, providing an important target for ongoing research.

Abstract
BACKGROUND Lipofilling is a treatment modality to restore tissue volume. Both platelet-rich plasma and adipose-derived stromal cells have been reported to augment the efficacy of lipofilling, yet results are not conclusive. The authors hypothesized that the variation reported in literature is caused by a dose-dependent influence of platelet-rich plasma on adipose-derived stromal cells. METHODS Whole blood (n = 3) was used to generate platelet-rich plasma, which was diluted with Dulbecco's Modified Eagle Medium to 15%, 5%, and 1.7%, with 15% platelet-poor plasma and 10% fetal calf serum as controls. Pooled adipose-derived stromal cells (n = 3) were cultured in these media. Gene expression was assessed, along with angiogenic sprouting of endothelial cells by conditioned medium and platelet-rich plasma. RESULTS platelet-rich plasma in culture medium affected the expression of genes in a dose-dependent manner. The 15% concentration stimulated proliferation almost eightfold. Mesenchymal markers were unaffected. Interestingly, expression of collagens type 1 and 3 increased at lower concentrations, whereas transforming growth factor-β showed reduced expression in lower concentrations. Proangiogenic gene expression was unaltered or strongly reduced in a dose-dependent manner. platelet-rich plasma promoted endothelial sprouting and survival in a dose-dependent manner; however, conditioned medium from adipose-derived stromal cells exposed to platelet-rich plasma blocked endothelial sprouting capabilities. CONCLUSION The dose-dependent influence of platelet-rich plasma on the therapeutic capacity of adipose-derived stromal cells conditioned medium in vitro warrants caution in clinical trials.

Abstract
BACKGROUND The survival of autologous fat graft tissue is dependent on various factors, such as vascularization and inflammation. OBJECTIVE This study aims to evaluate the possible beneficial effects of dimethylsulfoxide (DMSO) on fat graft volume and survival. METHODS Eighteen male Wistar albino rats were divided randomly into three groups. An autologous fat graft obtained from the inguinal region of each rat was transferred to its back. DMSO was administered intraperitoneally (IP) in the DMSO-IP group and cutaneously (C) in the DMSO-C group once daily for 15 days after the surgical procedure. The control group underwent surgery but was not administered with DMSO. Two months after surgery, the grafted fatty tissues were harvested for histopathological and biochemical analyses. RESULTS The results showed that 2 months postoperatively, fat grafts of the DMSO-C and DMSO-IP groups weighed significantly more than the grafts of the control group. Moreover, the vascularity of the grafts was higher in the DMSO-C group than in the control group, and no significant difference was found between the two DMSO groups. The mean lipid peroxidation levels were the same in the three groups, but myeloperoxidation was significantly lower in the DMSO-C group than in the other two groups. CONCLUSIONS The study results showed that cutaneous rather than intraperitoneal DMSO administration could preserve the quality and volume of transplanted fat tissue in rats by enhancing vascularity and decreasing inflammation.

Abstract
In facial plastic surgery, the potential for direct delivery of growth factors from platelet preparations has been of particular interest for use in facial rejuvenation, recovery after facial surgery, and wound healing. A literature search was conducted through PubMed for the terms PRP, PRFM, platelet-rich plasma, platelet-rich fibrin matrix, platelet preparations, platelet therapy, growth factors, platelet facial, platelet facial rejuvenation, platelet wound healing, platelet plastic surgery. Articles pertaining to the use of platelet preparations in facial surgery and wound healing in plastic surgery after 2001 were included. Thirteen in vitro studies showed use of platelet-rich plasma (PRP) and platelet-rich fibrin matrix (PRFM) had a significant effect on cellular activity. Twenty-four out of 28 animal studies exhibited favorable results with use of a platelet preparation, including five of six studies that showed enhanced fat graft survival with addition of a platelet preparation. Twenty-three case series and clinical trials were identified, only two of which showed no differences. Twenty-one reported favorable results with use of various platelet preparations. A total of 47 studies used PRP, four studies evaluated Leukocyte-rich PRP, and fourteen studies used PRFM. The vast majority of studies examined show a significant and measurable effect on cellular changes, wound healing, and facial esthetic outcomes with use of platelet preparations, both topical and injectable. One must also consider possible publication bias against null results that may have had an influence on the data that were available for review. However, the preponderance of studies suggests that platelet preparations might represent an as-of-yet untapped adjunct in facial plastic surgery.

Abstract
Platelet-rich plasma (PRP) has been tested in vitro, in animal models, and clinically for its efficacy in enhancing the rate of wound healing, reducing pain associated with injuries, and promoting axon regeneration. Although extensive data indicate that PRP-released factors induce these effects, the claims are often weakened because many studies were not rigorous or controlled, the data were limited, and other studies yielded contrary results. Critical to assessing whether PRP is effective are the large number of variables in these studies, including the method of PRP preparation, which influences the composition of PRP; type of application; type of wounds; target tissues; and diverse animal models and clinical studies. All these variables raise the question of whether one can anticipate consistent influences and raise the possibility that most of the results are correct under the circumstances where PRP was tested. This review examines evidence on the potential influences of PRP and whether PRP-released factors could induce the reported influences and concludes that the preponderance of evidence suggests that PRP has the capacity to induce all the claimed influences, although this position cannot be definitively argued. Well-defined and rigorously controlled studies of the potential influences of PRP are required in which PRP is isolated and applied using consistent techniques, protocols, and models. Finally, it is concluded that, because of the purported benefits of PRP administration and the lack of adverse events, further animal and clinical studies should be performed to explore the potential influences of PRP.

Abstract
BACKGROUND One of the most interesting developments in practical applications of fat grafting in recent years is the use of prosurvival strategies to improve maintenance of volume. Platelet-rich plasma (PRP) plays a decisive role in the repair and regeneration of different tissues via the activation and secretion of a great variety of growth factors and other cytokines stored in the alpha-granules of the platelets. This review aimed to assess the efficacy of PRP mixed-fat grafting as a prosurvival strategy for fat grafts. METHODS Online searches of the Cochrane Library and MEDLINE until January 2014 were conducted. The review included studies with at least one clinical end point in which the effect of PRP on the absorption and viability of the fat graft could be assessed. RESULTS The review comprised 6 preclinical studies with a control group and 9 clinical studies of humans. It also included comparative studies performed with other prosurvival strategies for fat grafts, such as combination with the stromal vascular fraction and second-generation PRP, also called "platelet-rich fibrin." The results indicate that PRP may have a dose-dependent positive effect on fat grafts and suggest low complication rates. CONCLUSIONS The development of new growth factor delivery systems or cell therapies to enrich fat grafts is an area that merits further research.

Abstract
BACKGROUND This study focused on the possible effect of platelet-rich plasma (PRP) on recovery time and aesthetic outcome after facial rejuvenation. We conducted a retrospective analysis with regard to recovery time and the aesthetic improvement after treatment among four groups of patients: those treated with fat grafting only (Group I), those treated with fat grafting and PRP (Group II), those treated with a minimal access cranial suspension (MACS)-lift and fat grafting (Group III), and those treated with a MACS-lift, fat grafting, and PRP (Group IV). METHODS For the first part of this study, i.e., evaluation of recovery time after surgery, the following selection criteria were used: nonsmoking females, aged 35-65 years, with a complete documented follow-up. In total, 82 patients were included in the evaluation of patient-reported recovery time. For the second part of the study, i.e., evaluation of potential differences in aesthetic outcome, the records of these 82 patients were screened for the presence of pre- and postoperative standardized photographs in three views (AP, lateral, and oblique), leaving 37 patients to evaluate. A questionnaire was developed to evaluate the aesthetic outcome in all four groups of patients. This questionnaire was given to an expert panel that consisted of ten plastic surgeons. RESULTS The addition of PRP to a lipofilling procedure resulted in a significant drop in the number of days needed to recover before returning to work or to restart social activities [Group I (no PRP) took 18.9 days vs Group II (PRP) took 13.2 days, p = 0.019]. There seemed to be no effect when PRP was added to a MACS-lift + lipofilling procedure. Also, the aesthetic outcome of the lipofilling and MACS-lift + lipofilling groups that received PRP (Groups II and IV) was significantly better than the groups without PRP (Groups I and III). CONCLUSIONS Adding PRP to facial lipofilling reduces recovery time and improves the overall aesthetic outcome of a MACS-lift.

Abstract
In recent years, the use of platelet-rich plasma has increased notably in a range of diseases and settings. Uses of these products now go beyond skin rejuvenation therapy in patients with facial ageing. Good outcomes for other dermatological indications such as skin ulcers and, more recently, alopecia have been reported in case series and controlled studies. However, these indications are not currently included in the labeling given that stronger scientific evidence is required to support their real benefits. With the increased use of these products, dermatologists need to become familiar with the underlying biological principles and able to critically assess the quality and outcomes of the studies of these products in different skin diseases.

Abstract
Due to the natural properties of fat, fat grafting remains a popular procedure for soft tissue volume augmentation and reconstruction. However, clinical outcome varies and is technique dependent. Platelet-rich plasma (PRP) contains α-granules, from which multiple growth factors such as platelet-derived growth factor, transforming growth factor-β, vascular endothelial growth factor, and epidermal growth factor can be released after activation. In recent years, the scope of PRP therapies has extended from bone regeneration, wound healing, and healing of musculoskeletal injuries, to enhancement of fat graft survival. In this review, we focus on the definition of PRP, the different PRP preparation and activation methods, and growth factor concentrations. In addition, we discuss possible mechanisms for the role of PRP in fat grafting by reviewing in vitro studies with adipose-derived stem cells, preadipocytes, and adipocytes, and preclinical and clinical research. We also review platelet-rich fibrin, a so-called second generation PRP, and its slow-releasing biology and effects on fat grafts compared to PRP in both animal and clinical research. Finally, we provide a general foundation on which to critically evaluate earlier studies, discuss the limitations of previous research, and direct plans for future experiments to improve the optimal effects of PRP in fat grafting.

Abstract
BACKGROUND The aim of this study was to compare the effects of preoperative subcutaneous platelet-rich plasma and fibrin glue administration on skin flap survival. METHODS One week before surgery; saline, platelet-rich plasma, fibrin glue, and thrombin solutions were applied under rat skin flap areas in Groups I, II, III, and IV, respectively. Unipedicled epigastric flaps were elevated in the first three groups but could not be elevated in Group IV because of preoperative abdominal skin necrosis. Necrotic area measurements, microangiography, and histological and immunohistochemical evaluations were performed. RESULTS Platelet-rich plasma reduced the percentage of necrotic area when compared to other groups. Histologically and microangiographically an increased number of arterioles were observed in the platelet-rich plasma group. Thrombin (when used alone) caused abdominal skin necrosis. Increased expression of VEGF and PDGF was found in all platelet-rich plasma-treated flaps. There was no significant difference between groups with respect to TGF-β3 staining intensity. CONCLUSION In this study preoperative administration of platelet-rich plasma mimicked the pharmacological delay effect and enhanced flap survival. Individual use of thrombin was found to be unsuitable in flap surgery. LEVEL OF EVIDENCE I This journal requires that authors assign a level of evidence to each article.
