Despite the popularity of lipofilling procedures in recent years, the presence of older habits still in fat graft harvesting and processing seems to be the biggest obstacle to the final better outcome of fat grafting. Our study is aimed to highlight some strategies what should be done in fat grafting in the shadow of evidence-based medicine and patient-reported outcomes which might be of interest to the clinicians. Between 2015 and 2017, 14 patients were included who underwent facial micro-autologous fat transplantation with platelet-rich plasma injection...

Adipose tissue yields adult adipose stem cells (ASCs) in large quantities via less-invasive methods. These cells are of interest owing to their modulating properties and paracrine activities, which can be harnessed in regenerative medicine. Many studies on the use of rat fat tissue in an autologous animal model have been conducted; however, the different locations to obtain stromal vascular fraction of rat fat depots have not been fully characterized. The purpose of the current study was to identify optimal source of ASC from various locations of rat body...

Background: Lower blepharoplasty has been used for rejuvenating lower eyelids, and diverse modifications have been used to treat conjunct deformities at the tear trough/lid-cheek junction. Strategies for recontouring prominent tear trough/lid-cheek junctions, including orbital fat manipulation, have been reported with good results in the literature. Micro-autologous fat transplantation (MAFT) is a previously unevaluated, potentially advantageous approach to blending the prominent tear trough/lid-cheek junction...

BACKGROUND: Autologous fat transplantation (AFT) is being increasingly used to improve the results after breast-conserving surgery and breast reconstruction. However, studies on patient-reported outcomes (PROs) and health-related quality of life (HRQoL) after AFT are scarce. The aim of this prospective longitudinal case-series study was to assess PRO in women who had undergone AFT after surgery for breast cancer or risk-reducing mastectomy. METHODS: Fifty women, who had undergone breast-conserving surgery or breast reconstruction, needing corrective surgery, were consecutively included between 2008 and 2013...

BACKGROUND: Barraquer-Simons syndrome (BSS) or acquired partial lipodystrophy is a disorder of loss of subcutaneous fat from the upper part of the body. The resulting cosmetic disfigurement causes significant psychological distress in the affected individuals. Fillers, autologous fat transplant or cosmetic surgeries can be used to correct the volume deficit. METHODS: The authors report a case of a young woman, who presented with gradual loss of subcutaneous fat from the face, upper limbs, and trunk...

RATIONALE: Several studies have suggested a role for the gut microbiota in inflammation and atherogenesis. A causal relation relationship between gut microbiota, inflammation and atherosclerosis has not been explored previously. OBJECTIVE: Here, we investigated whether a pro-inflammatory microbiota from Caspase1-/- ( Casp1-/- ) mice accelerates atherogenesis in Ldlr-/- mice. METHODS AND RESULTS: We treated female Ldlr-/- mice with antibiotics and subsequently transplanted them with fecal microbiota from Casp1-/- mice based on a co-housing approach...

BACKGROUND: Autologous fat grafting has become an increasingly common procedure for soft tissue augmentation throughout the body. However, the long-term outcome is always unpredictable because of inconsistent graft survival. Based on the "law of use and disuse," we speculate that the volume loss of fat grafts will occur when transferred into a site where there is less fat. The purpose of this study is to investigate the cause of high resorption rate from the perspective of fat function after transplantation...

Folliculitis decalvans is a rare clinical disorder classified as primary neutrophilic scarring alopecia with a slight preference for the male gender. Here, we report the use of autologous fat transplantation as a source of stem cell therapy for hair re-growth assisted by inflammatory action of the fat itself in a female patient. The patient underwent adipose transplantation in April and September 2017. After treatments, the patient had no new pustules and no longer had pain or burning sensation in the affected area...

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...

Despite its reliability, radial forearm (RF) flap is still affected by high donor site morbidity with poor cosmetic and functional outcomes after coverage with skin grafts. Having fat grafting demonstrated promising and effective filling and rejuvenating properties, we considered and tested it as a valuable alternative to dermal substitutes for the aesthetic improvement of RF flap donor site. Thirty-three patients with previous RF free flap reconstruction and poor donor site outcomes after full-thickness skin grafting to RF region were evaluated for secondary fat injection to improve outcomes...

Adipose‑derived stem cells (ASCs) can easily be obtained and expanded in vitro for use in autologous cell therapy. Via their production of cytokines and neurotrophic factors, transplanted ASCs provide neuroprotection, neovascularization and induction of axonal sprouting. However, the influencing mechanism of undifferentiated ASCs on nerve regeneration is currently only partially understood. In the present study, undifferentiated ASCs and cutaneous primary afferent dorsal root ganglion (DRG) neurons were co‑cultured in order to investigate their interaction...

Adipose-derived mesenchymal stem cells (ADSCs) have attracted attention due to their potential for use in the treatment of various diseases. However, the self-renewal capacity of ADSCs is restricted and their function diminishes during passage. We previously generated induced tissue-specific stem cells from mouse pancreatic cells using a single synthetic self-replicating Venezuelan Equine Encephalitis (VEE)-reprogramming factor (RF) RNA replicon (SR-RNA) expressing the reprogramming factors POU class 5 homeobox 1 (OCT4), Krueppel-like factor 4 (KLF4), Sex determining region Y-box 2 (SOX2), and Glis Family Zinc Finger 1 (GLIS1)...

AIM OF THE STUDY: The use of autologous bio-engineered dermo-epidermal skin substitutes (DESS) yields a pivotal opportunity to cover large skin defects in human patients. These skin grafts consist of both epidermal and dermal compartments necessary for robust and permanent functional wound closure. In this study, we investigated the impact of mesenchymal cells derived from different body site origins on the expression pattern of diverse markers within DESS. METHODS: Human keratinocytes were obtained from interfollicular epidermis, and mesenchymal cells were isolated from foreskin, palmar skin, fat tissue, and tonsils...

Since the mechanisms of scar formation are not fully understood, at least to date, there is no ideal method to prevent and treat scar after burn. In recent years, on the basis of conventional treatments, such as pressure therapy, external use of silicone gel, and intralesional injections of corticosteroids, the therapeutic approaches of fractional carbon dioxide laser treatment, injection of anti-vascular endothelial growth factor antibody, autologous fat transplantation, injection of botulinum toxin A, radiation therapy etc...

BACKGROUND: In Crohn's disease, it is essential to distinguish between persistent damage and abnormalities that can heal with anti-inflammatory therapy. AIM: To magnetic resonance enterography (MRE) lesions that persist in patients in long-standing endoscopic remission, analyse their relationship with baseline characteristics, and determine their prognostic implications. METHODS: We systematically reviewed pre- and post-treatment MRE findings in patients with Crohn's disease and severe inflammation (segmental CDEIS ≥ 7 or ulcers in at least one segment) who achieved endoscopic remission (CDEIS < 2) after 1 year of treatment with TNF-inhibitors or autologous haematopoietic stem-cell transplantation...

Graft-versus-host-disease (GVHD) following stem cell transplantation (SCT) is a common complication in patients that have undergone allogenic SCT but rare in recipients of autologous SCT. Gastro-intestinal tract (GIT)-GVHD can be difficult to diagnose due to non-specific symptoms such as fever, nausea, diarrhea, and vomiting; a histological confirmation is therefore required. Here, we present the findings of a whole-body 18 FDG PET/CT with extensive and multifocal involvement of the GIT in a patient that developed severe acute GVHD 93 days post autologous SCT for Hodgkin's lymphoma...

Introduction: Autologous transplantation of adipose stromal vascular fraction (SVF) is a cost-effective and technically accessible option for cell therapy. Clinical study of SVF transplantation for male stress urinary incontinence (SUI) is underway, but the effectiveness remains unknown for female SUI, majority of which is caused by childbirth trauma. Methods: Vaginal Distension (VD) rats were generated as in vivo model for female SUI. To quantitate the severity of SUI, leak point pressure (LPP) was measured by placing a bladder catheter...

Objective: Adipose-derived stem cells (ASCs) are capable of multiple differentiation pathways, imparting immunomodulatory effects, and secreting factors that are important for wound healing. These characteristics can be exploited to decrease the incidence of anastomotic leakage. Methods: In order to delay local wound healing at the anastomotic site, we induced ischemia in a portion of porcine small intestine by ligating vessels. Then, we injected mitomycin C into the serosa of the small intestine above the ligated vessels...
