Abstract
BACKGROUND Nanofat and lipoconcentrate contain adipose-derived stem cells and growth factors, and have wide clinical applications in the regenerative field. This study aimed to investigate the microenvironmental changes associated with nanofat and lipoconcentrate. METHODS Conventional fat, nanofat, or lipoconcentrate (0.2 mL each, n = 5 per group) were injected subcutaneously into the dorsal flanks of athymic nude mice. The graft weights were measured at postoperative week 4; the grafts and their overlying skin were used for histological analyses. RESULTS Weights of the lipoconcentrate grafts were significantly greater than those of the conventional fat (p < 0.05) and nanofat (p < 0.01) grafts. There was no significant difference in inflammation, oil cysts, and fibrosis between the conventional fat and nanofat groups. Histological examination of the lipoconcentrate grafts showed less macrophage infiltration and the formation of fibrosis and oil cysts. Additionally, adipogenesis and angiogenesis were induced more in the lipoconcentrate grafts than in the nanofat grafts (p < 0.01). Lipoconcentrate and nanofat improved dermal thickness (p < 0.001 and p < 0.01, respectively, versus the baseline). CONCLUSION Lipoconcentrate grafts had greater volume and shape retention than conventional fat and nanofat grafts. They had better histological structure and acted as scaffolds for adipogenesis and angiogenesis. Both products showed regenerative effects on dermal thickness; however, only lipoconcentrate grafts had the required volume and regenerative effects, allowing it to serve as a novel adipose-free grafting method for facial rejuvenation and contouring.

Abstract
BACKGROUND Tear trough deformity makes patients appear tired. Patients with less severe tear trough deformity prefer a less invasive method to correct the deformity. The infraorbital area is a multilayered tissue, and the aging of various components leads to tear trough deformity. To this end, we utilized the different characteristics of different fat derivatives to correct tear trough deformity. METHODS Thirty-two patients with Barton Grade I/II tear trough deformity were enrolled in this study between September 2020 and March 2021. We injected Stromal Vascular Fraction Gel (SVF-Gel) into the suborbicularis oculi fat layer and Nanofat into the subcutaneous. After 12 months of follow-up, we evaluated the changes using standardized clinical photogrammetric techniques, volume, global aesthetic improvement scale, and patient self-evaluation. RESULTS There were no major complications in any of the 32 patients. The measured data points demonstrated improvements in all aesthetic parameters. The width of the tear trough and the distance from the pupil to the tear trough improved. The Global Aesthetic Improvement Scale (GAIS) showed a high score (2.45±0.64 points), with patient self-assessment showing satisfactory results. CONCLUSION SVF-Gel combined with Nanofat injection can effectively correct tear trough deformities. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article.

Abstract
Introduction Postburn scarring often presents a specific reconstructive challenge from both functional and cosmetic perspectives. The purpose of this study was to investigate whether autologous nanofat harvested from the donor site of full skin or a skin flap can be reused for the treatment of early postburn scaring. Methods From July 2018 to April 2022, patients with early postburn scarring underwent scar reconstruction surgery with full-thickness skin or a skin flap for a contour deformity and/or scar contracture, and autologous nanofat grafting was performed during the same operation. The Vancouver Scar Score (VSS) and the itch and pain scores were evaluated at the preoperation time point as well as at 2-3 weeks and 3-months postoperation. A comparison was made among the same patients at different time points. Results A total of 17 patients, aged from 18 months to 62 years old were included in this analysis. The VSS was reduced from 10.00 ± 2.12 to 7.41 ± 1.277 at the 2-3-week postoperation time point, and to 5.53 ± 1.37 at the 3-month postoperation time point. The pain and itch score were reduced from 4.65 ± 1.37 and 6.35 ± 1.27, to 3.70 ± 1.10 and 4.94 ± 1.30 at the 2-3-week postoperation time point, and to 3.00 ± 1.28 and 3.94 ± 0.97 at the 3-month postoperation time point respectively. The VSS and pain and itch scores showed a statistically significant reduction (P < 0.05) at the 2-3-week and 3-month postoperative follow-ups compared with the preoperation time point. Conclusion Autologous nanofat grafting from donor sites of full thickness skin or skin flap may be a promising treatment for an early postburn scaring as it promotes scar softening, improves itching and pain within the scar. However, this is a small case series with only 17 patients. Further conclusions need to be drawn through expanded samples for randomized controlled clinical trials. Lay Summary Hypertrophic scarring is the most common complication after partial thickness burn injury, and the complex pathogenesis and prolonged dynamic process render treatments only marginally effective. In the past few decades, with the technological advances of liposuction and fat grafting, nanofat grafting has been used in a variety of surgical fields, including wound healing, scleroderma, facial rejuvenation, and neuralgia. However, the role of nanofat grafting is not well documented in the prevention and treatment of early postburn scarring. Full-thickness skin grafting or skin flap transplantation is the most common method for the reconstruction of a hypertrophic scaring until now. In the current study, we harvested subcutaneous fat during the preparation of the full-thickness skin or skin flap, prepared nanofat and injected it in the scar located at a nonsurgical site. Comparison of the pre- and postoperation scores for scar color, scar thickness, scar stiffness, and scar regularity showed that the postoperation scores were decreased significantly and that there was a significant improvement in scar pigmentation and thickness as well astheaesthetic outcome after treatment. Most importantly, reductions in the scores for pain and itching could be assessed objectively. It seems that the nanofat grafting is a potential method for prevention and treatment for early postburn scaring.

Abstract
INTRODUCTION Nerve autograft is the gold standard for reconstruction of peripheral nerve loss. The alternative is the interposition of a synthetic regeneration conduit. The purpose of the study was to evaluate the in vivo feasibility and interest of Adipose-Derived Stem Cells (ADSCs) using the Nanofat technique and chitosan conduit for peripheral nerve defect repair. MATERIAL AND METHODS In vivo, after the creation of a 10 mm defect of the sciatic nerve, 2 groups were defined according to the nerve repair in rats: "chitosan" group (n = 10) and "chitosan and ADSCs" group (n = 10) with a clinical and paraclinical evaluation at 7 weeks. RESULTS The in vivo results seem to show that the adjunction of ADSCs was favorable clinically, histologically and functionally compare to a chitosan reconstruction alone. DISCUSSION Peripheral nerve repair with defect using a chitosan conduit associated with ADSCs would constitute a surgical alternative in a single surgical step.

Abstract
BACKGROUND Acne is a common chronic inflammatory disease, which can result in permanent scarring. Different types of treatments have been used in order to treat acne scars. However, esthetic results have proved variable. Furthermore, none of these treatments has had an impact on the underlying inflammatory process. OBJECTIVE The main purpose of this case-report is to suggest a new potential therapy for acne scar management combining esthetic filling with an anti-inflammatory and a regenerative action. METHODS A Platelet rich plasma (PRP) and Nanofat mixture was injected into the pathological dermis in order to treat and fill severe acne scars. RESULTS After a one- year follow-up, skin elasticity had improved, scar reduction and a reversal of the inflammation process had been observed. CONCLUSIONS PRP and Nanofat could represent a new and promising therapeutic approach in the treatment of the inflammatory scarring process in severe acne.

Abstract
BACKGROUND Nanofat, as a derivative of adipose tissue, has gradually become a research hotspot in beauty and regenerative medicine. However, the nanofat preparation method has not yet been standardized; it remains unknown whether the aperture of the connector has any influence on the transplantation effect. METHODS Adipose tissue was mechanically emulsified into nanofat tissue through different connector apertures (1.0, 1.5, and 2.0 mm). Cell survival and apoptosis were measured using the volume of oil droplets, glucose transportation test, flow cytometry, cell counting kit-8 (CCK-8), wound healing assay, transwell migration assay, and fluorescence staining. The expression of adiponectin, GluT4, and PPAR-γ in nanofat-derived stem cells (NFSCs) was detected using quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS The fineness of nanofat tissue texture decreased with an increase in the aperture connector. The amounts of glucose transferred in the three groups (1, 1.5, and 2 mm) were 4.7 ± 0.894, 6.1 ± 1.026, and 6.9 ± 0.868 mmol/L, respectively. Flow cytometric analysis showed that the proportion of NFSCs in the 2.0 mm group was the highest (91.267±1.210%). Cell proliferation and migration abilities were stronger in the 1.5 and 2.0 mm groups. The numbers of late apoptotic and dead cells in the 2.0 mm group were significantly fewer than those in the two other groups. Expression levels of lipid-related genes were as follows: adiponectin > GluT4 > PPAR-γ in each component. CONCLUSIONS As nanofat is emulsified, the use of larger aperture connectors (2.0 mm) appeared to decrease the degree of adipocyte lysis and increase the biological activity of adipose tissue.

Abstract
Nanofat (NF) is a fine emulsion that has been used to treat a variety of diseases given its abundance of bioactive components. However, the biological functions of NF have been limited due to its inability to localize during implantation. In this study, NF was immobilized in microfluidic-generated aldehyde-modified polylactic glycolic acid (PLGA) porous microspheres (PMs) via Schiff base condensation and non-covalent binding in a three-dimensional (3D) porous network (PMs@NF). The PMs effectively enhanced the cartilage-targeted retention efficiency of NF, which also resulted in remarkable lubrication performance, with the friction coefficient being reduced by ∼80%, which was maintained over time. Meanwhile, the 3D penetrating structure of the microspheres stimulated cytokine secretion by the NF-derived stem cells, upregulating the expression of anabolism-related genes and downregulating catabolism, and the expression of inflammation-related and pain-related genes. Injecting PMs@NF into the knee joint cavity of a rat model with destabilization of the medial meniscus (DMM) reduced osteophyte formation and protected the cartilage from degeneration, thereby inhibiting the progression of osteoarthritis and improving animal behavior. In summary, this study developed a multifunctional platform with NF immobilization and super-lubrication, which showed great potential for the minimally invasive treatment of osteoarthritis.

Abstract
BACKGROUND Fat grafting has been extensively applied as natural filler and has been very promising in restoring volume loss. Lipografting has also been credited to reduce age-related skin changes due to the regenerative potential of adipose derived stem cells. Cell-mediated therapies in plastic surgery are rapidly evolving with growing applications. Nanofat, a bio-regenerative liquid suspension rich in stromal vascular fraction cells without viable adipocytes, has been described as an efficient cutaneous anti-aging therapy. We have published in 2013 a review entitled "stem cell facelift: between reality and fiction." Available clinical evidence at that time did not substantiate marketing and promotional claims of "stem cell facelift". The same year, the report about nanofat was published demonstrating striking clinical outcome. The current literature search is aimed at reviewing any evidence that has emerged since then regarding clinical efficacy of this modality. METHODS A thorough PICO tool-based comprehensive literature search of PubMed database for "the efficacy of nanofat cell-mediated anti-aging therapy" was conducted with a time frame from 2013 till present. RESULTS Despite apparent increasing popularity of stem cell rejuvenation, well-controlled clinical studies about this modality are surprisingly very scarce. Only seven papers published after 2013 were identified and were included in this review CONCLUSION: Though considered to be a safe procedure, and despite documented histologic improvement and striking clinical outcome in some reports, available evidence can hardly support clinical improvement of skin quality. Before cell-mediated aesthetic rejuvenation applications can be routinely undertaken, more robust evidence with well-defined primary outcome end points and objective outcome measures is required.

Abstract
Adipose tissue is a compact and well-organized tissue containing a heterogeneous cellular population of progenitor cells, including mesenchymal stromal cells. Due to its availability and accessibility, adipose tissue is considered a “stem cell depot.” Adipose tissue products possess anti-inflammatory, anti-fibrotic, anti-apoptotic, and immunomodulatory effects. Nanofat, being a compact bundle of stem cells with regenerative and tissue remodeling potential, has potential in translational and regenerative medicine. Considering the wide range of applicability of its reconstructive and regenerative potential, the applications of nanofat can be used in various disciplines. Nanofat behaves on the line of adipose tissue-derived mesenchymal stromal cells. At the site of injury, these stromal cells initiate a site-specific reparative response comprised of remodeling of the extracellular matrix, enhanced and sustained angiogenesis, and immune system modulation. These properties of stromal cells provide a platform for the usage of regenerative medicine principles in curbing various diseases. Details about nanofat, including various preparation methods, characterization, delivery methods, evidence on practical applications, and ethical concerns are included in this review. However, appropriate guidelines and preparation protocols for its optimal use in a wide range of clinical applications have yet to be standardized.

Abstract
Background Osteoarthritis (OA) is the most common joint degenerative disorder, with little effective therapy to date. Nanofat is a cocktail of cells obtained from fat tissue, which possesses regenerative capacity and has a potential in treating OA. This study aimed to determine the anti-OA efficacy of Nanofat from basic and clinical aspects and explore its action mode. Methods Flow cytometry was performed to characterize Nanofat. A monoiodoacetate-induced OA rat model was employed for in vivo study. Cell viability and wound healing assays were conducted for in vitro study. Real-time PCR and Western blot assays were applied to explore the molecular action mode of Nanofat. Moreover, a retrospective analysis was conducted to determine the clinical efficacy and safety of Nanofat on knee OA patients. Results The in vivo results showed that Nanofat significantly attenuated pain symptoms and protected cartilage ECM (Col2) from damage, and its effects were not significantly differed with adipose tissue-derived stem cells (both P > 0.05). The in vitro results showed that Nanofat promoted the cell viability and migration of chondrocytes and significantly restored the IL-1β-induced abnormal gene expressions of Col2, Aggrecan, Sox9, Adamts5, Mmp3, Mmp9 Mmp13, IL-6 and Col10 and protein expressions of Col2, MMP9, MMP13, and Sox9 of chondrocytes. The regulatory actions of Nanofat on these anabolic, catabolic, and hypertrophic molecules of chondrocytes were similar between two treatment routes: co-culture and conditioned medium, suggesting a paracrine-based mode of action of Nanofat. Moreover, the clinical data showed that Nanofat relieved pain and repaired damaged cartilage of OA patients, with no adverse events. Conclusion In sum, this study demonstrated the anti-OA efficacy as well as a paracrine-based action mode of Nanofat, providing novel knowledge of Nanofat and suggesting it as a promising and practical cell therapy for clinical treatment of OA.

Abstract
The most important and greatest source in the body for regenerative cells is fat tissue. Obtaining regenerative cells from adipose tissue can be done in two ways: Enzymatic and mechanical. The regenerative cell cocktail obtained by the enzymatic method, including stem cells, is called Stromal vascular fracture (SVF). In the literature, there is no clear definition of regenerative cells obtained by mechanical method. We systematically searched the techniques and definitions for stromal cells obtained from adipose tissue by scanning different databases. To evaluate the mechanical stromal-cell isolation techniques and end products from adipose tissue. Systematic review of English and non-English articles using Embase, PubMed, Web of Science and Google scholar databases. Search terms included Nanofat, fragmented fat, mechanical stromal / stem cell, mechanical SVF, SVF gel. We screened all peer-reviewed articles related with mechanical stromal-cell isolation. Author performed a literature query with the aforementioned key words and databases. A total of 276 publications containing the keywords we searched were reached. In these publications, there are 46 different definitions used to obtain mechanical stromal cells. The term SVF is only suitable for enzymatic methods. A different definition is required for mechanical. The most used term nanofat is also not suitable because the product is not in both "fat" and in "nanoscale". We think that the term total stromal-cells would be the most appropriate definition since both extracellular matrix and all stromal cells are protected in mechanical methods.

Abstract
Scar is a kind of skin fibroproliferative disease characterized by excessive repair of skin tissue and disorganized deposition of extracellular matrix resulting from deep dermal injury caused by burns or trauma. Scar is accompanied by symptoms such as itching and pain, which could lead to appearance damage and psychological disorders, and is one of the common diseases in burns and plastic surgery clinics. Currently, transplantation of adipose tissue and components is considered as one of the most cutting-edge treatments for scar. Adipose components transplantation includes transplantation of nanofat, adipose-derived stem cell matrix gel, stromal vascular fraction, and adipose-derived stem cell. More and more studies showed that adipose tissue and components possess the functions of tissue regeneration, extracellular matrix remodeling, and anti-fibrosis, which could improve the appearance and symptoms of scar by local transplantation. Therefore, this paper reviews the effects of adipose tissue and components transplantation on scar treatment, aiming to provide theoretical reference for adipose treatment of scar.

Abstract
Reparative, angiogenic, and immunomodulatory properties have been attributed to the cells in the adipose tissue-derived stromal vascular fraction. Because of these characteristics, in the last decade, fat grafting for treatment of autoimmune diseases has grown. This article focuses on systemic sclerosis, a rare autoimmune disease characterized by skin fibrosis and microvascular damage. Lesions of the face are almost always present; however, current therapy is insufficient and patients have considerable disability and social discomfort. This article presents our approach to using fat grafting in the face as an innovative and promising therapy for patients with systemic sclerosis.

Abstract
Fat grafting is as a unique regenerative filler with soluble factors and progenitor cells that may remodel scar tissue in an easy yet effective way. A combination of microfat grafting, lipococoncentrate injection, scar subcision, and platelet-rich plasma supplementation may be used to treat the majority of facial scars. The lipoconcentrate technique condenses the lipoaspirate to a progenitor cell-rich fluid of low volume by a combination of centrifugation and emulsification steps. In this article, the authors' methods for scar treatment by fat grafting are discussed. Choice of technique for facial scars, precise indications, and contraindications are introduced.

Abstract
Cellular and cell-derived components of adipose-derived tissue for the purposes of dermatologic and aesthetic rejuvenation applications have become increasingly studied and integrated into clinical practice. These components include micro-fragmented fat (nanofat), the stromal vascular fraction (SVF), adipose-derived mesenchymal stem cells (ASC), and extracellular vesicles (EVs), which have all shown capability to repair, regenerate, and rejuvenate surrounding tissue. Various aesthetic applications including hair growth, scar reduction, skin ischemia-reperfusion recovery, and facial rejuvenation are reviewed. In particular, results from preclinical and clinical studies are discussed, with a focus on clarification of nomenclature.

Abstract
BACKGROUND Nanofat and fat graft survival is an important clinical problem. The authors of this study investigated whether PRP has an impact on fat and nanofat graft survival and vascularization in a mouse model. MATERIALS AND METHODS Fat was harvested from a 50-year-old healthy woman by vacuum suction, and nanofat was obtained by emulsification and centrifugation procedures. PRP was collected after two rounds of centrifugation from an autologous blood sample. Twenty male nude mice were divided into four treatment groups: PRP/nanofat, PRP/fat, saline/nanofat and saline/fat. After 1 month and 3 months, the grafts were extracted and weighed. The microstructure of the fat and nanofat was examined with a scanning electron microscope. HE and immunohistochemical staining was applied to observe neovascularization. Western blot analysis was used to analyse the expression of CD31 and VEGF. RESULTS In fat tissue, fat cells had normal connections; the fat structure was complete and fibre networks were visible. In nanofat, the extracellular matrix vascular components were visible and their structures were intact. At 1 month and 3 months, the graft weights in the PRP/fat group were significantly higher than those in the other groups. Further, a higher degree of neovascularization was observed in the PRP/nanofat group, and the expression of CD31 and VEGF in the PRP/nanofat group was higher than that in the other groups. CONCLUSION PRP can promote nanofat and fat graft survival and vascularization. NO LEVEL ASSIGNED This journal requires that authors assign a level of evidence to each article.

Abstract
Background Our previous study proved that nanofat could enhance fat graft survival by promoting neovascularization. Fat extract (FE), a cell-free component derived from nanofat, also possesses proangiogenic activity. Objectives The aim of this study was to investigate whether FE could improve fat graft survival and whether FE and nanofat could work synergistically to promote fat graft survival. The underlying mechanism was also investigated. Methods In the first animal study, human macrofat from lipoaspirate was co-transplanted into nude mice with FE or nanofat. The grafts were evaluated at 2, 4 and 12 weeks post-transplantation. In the second animal study, nude mice were transplanted with a mixture of macrofat and nanofat, followed by intra-graft injection of FE at days 1, 7, 14, 21 and 28 post-transplantation. The grafts were evaluated at 12 weeks post-transplantation. To detect the mechanism by which FE impacts graft survival, the proangiogenic, anti-apoptotic and pro-proliferative activities of FE were analysed in grafts in vivo and in cultured human vascular endothelial cells (HUVECs), adipose-derived stem cells (ADSCs) and fat tissue in vitro. Results In the first animal study, the weights of the fat grafts in the nanofat- and FE-treated groups were significantly higher than those of the fat grafts in the control group. In addition, higher fat integrity, more viable adipocytes, more CD31-positive blood vessels, fewer apoptotic cells and more Ki67-positive proliferating cells were observed in the nanofat- and FE-treated groups. In the second animal study, the weights of the fat grafts in the nanofat+FE group were significantly higher than those of the fat grafts in the control group. In vitro, FE showed proangiogenic effects on HUVECs, anti-apoptotic effects on fat tissue cultured under hypoxic conditions and an ability to promote ADSC proliferation and maintain their multiple differentiation capacity. Conclusions FE could improve fat graft survival via proangiogenic, anti-apoptotic and pro-proliferative effects on ADSCs. FE plus nanofat-assisted fat grafting is a new strategy that could potentially be used in clinical applications.

Abstract
OBJECTIVE Emulsified fat injection showed its interest in aesthetic facial surgery. The adipose tissue harvested is mechanically emulsified and filtered. The suspension obtained is injected into the dermis through small diameter needles (27 to 30 gauges). The objective of our study was to evaluate the biological composition of emulsified fat and its clinical effectiveness in the treatment of peri-oral wrinkles in 4 patients aged 50 to 59 years. MATERIAL AND METHOD Each patient received an intradermal injection of emulsified fat in the peri-oral wrinkles prepared from abdominal fat under local anesthesia. The cell viability, stromal vascular fraction (FVS) composition in emulsified fat and the adipocyte differentiation capacity of mesenchymal stem cells (MSC) were studied. The clinical results were evaluated by standardized photographs, 3D microphotography, confocal microscopy, and self-evaluation of patient satisfaction over a period of 4 months. RESULTS The biological study of the emulsified fat found a lysis of all the adipocytes. The mean number of FVS cells was 126,330±2758 cells by cc of emulsified fat with preserved cell viability (85.1±6.84 %) and a good proportion of regeneratives cells (18.77±6.2 %). The clinical study found a tendency to decrease the volume of wrinkles on standardized photography and 3D microphotography no significative. Patients were satisfied with treatment with an average score of 7±1.15/10 to 4 months. CONCLUSION Intradermal injection of emulsified fat seems to be an interesting treatment of face wrinkles. Our study has shown its safety, but additional studies seems necessary to confirm its clinical efficacy.

Abstract
Zusammenfassung. Die Eigenfett-Therapie hat in der ästhetischen und plastisch-rekonstruktiven Chirurgie in den letzten Jahren zunehmend an Popularität gewonnen. Grundsätzlich können mit der Eigenfettmethode Volumendefizite behandelt werden. Die Brustrekonstruktion und Brustvergrösserung mit Eigenfett hat sich in den letzten Jahren als Alternative zur Verwendung von Silikongel-Implantaten entwickelt. Als Nebeneffekt zeigte sich eine Verbesserung der Hautqualität. Diese Beobachtungen schafften die Grundlage für die Anwendung von Eigenfett zur Narbentherapie. So kann das Fett nicht nur Volumen liefern, sondern durch seine regenerativen Eigenschaften auch in der Behandlung rigider und unschöner Narben eingesetzt werden. Die zugrundeliegenden Mechanismen sind nicht abschliessend geklärt. Klinische Studien zeigten gute Ergebnisse, sodass das Verfahren kontinuierlich weiterentwickelt wird.
