Islet transplantation is a promising alternative therapy for insulin-dependent patients, with the potential to eliminate life-threatening hypoglycemic episodes and secondary complications of long-term diabetes. However, widespread application of this therapy has been limited by inadequate graft function and longevity, in part due to the loss of up to 60% of the graft in the hostile intrahepatic transplant site. We report a proteolytically degradable synthetic hydrogel, functionalized with vasculogenic factors for localized delivery, engineered to deliver islet grafts to extrahepatic transplant sites via in situ gelation under physiological conditions...

AIM: Anal fistulas are common pathologies with a significant social impact; however their treatment is often complex and the recurrence rate can be significant. Some surgical treatments for fistula are also associated with the risk of sphincter injury. In this technical note, we aim to evaluate the feasibility and efficacy of the Fat GRAFT technique (Fat Grafting in Anal Fistula Treatment) in the treatment of recurrent anal fistulas. METHOD: All patients presenting with recurrent trans-sphincteric anal fistulas over an 18-month period were included...

BACKGROUND: Fat grafting experiences a regeneration process from free lipoaspirate to intact adipose tissue. The adipose extracellular matrix (ECM) provides the structure and biochemical support for the surrounding cells, and is regulated by inflammatory cells, like macrophages. It is hypothesized that transferred fat undergoes ECM remodeling after fat grafting and the process can be regulated by macrophage infiltration. METHODS: Lipoaspirate was injected subcutaneously into the back of nude mice...

INTRODUCTION: Autologous fat grafting (AFG) can be used as an adjunct in breast cancer surgery to improve contour defects. Few previous studies have assessed patient reported outcomes (PROs) for AFG. This study analysed AFG use and assessed PROs in terms of physical and psychosocial well-being. MATERIALS AND METHODS: All patients undergoing AFG were identified from a prospective database and asked to complete the validated BREAST-Q questionnaire and a tool to assess patient-perceived change after AFG (5-point Likert-type scale)...

BACKGROUND: Sunken upper eyelid is a commonly found deformity among Asians, mostly due to the aging process and excessive orbital fat removal during oriental blepharoplasty procedures. This deformity is frequently accompanied by multiple, poorly defined upper eyelid folds and blepharoptosis. To date, autologous fat graft has been the treatment of choice for this group of patients. However, accurate placement of the graft in the orbital fat is quite challenging, and it can result in contour irregularities when injected into the preseptal plane...

OBJECTIVES: In addition to its use as a volume filler, fat grafting may have a potential role in wound healing based on the concentration of growth factors in the lipoaspirate. In this study, we compare the quantitative and qualitative concentration of the various growth factors and adipokines using the Shippert or the Coleman techniques to prepare the lipoaspirate. METHODS: We measured leptin, adiponectin and the growth factors, i.e., acidic fibroblast growth factor (aFGF), basic FGF (bFGF), keratinocyte growth factor (KGF), bone morphogenetic protein-2 (BMP-2) and vascular endothelial growth factor (VEGF) by ELISA in solid and liquid fractions obtained with both techniques in human fat obtained with Coleman technique and Shippert technique...

Patients with hand muscular atrophy due to damage of the ulnar nerve could be stigmatized for their appearance. Unsatisfactory results in the attempt to correct the atrophy are reported in the literature. Fat grafting is an autologous and easily obtainable graft, antigenic response is very unlikely, it does not require any special material, and the procedure has a low cost. The technique of autologous fat grafting by using fat block, to remodel the first interdigital space, is useful and safe in correcting muscle atrophy of the first interdigital space caused by the injury of the ulnar nerve...

PURPOSE: To provide insight into the clinical anatomy of Tenon's capsule and to describe a technique to manage sclerocorneal defects using autologous Tenon's tissue. METHODS: A thin layer of Tenon's capsule harvested from the patient's own eye is used to seal the defect and act as a scaffold. The Tenon's flap is spread over the defect and held in place by Vicryl sutures. A bandage contact lens is then placed on the eye. RESULTS: Tenon's capsule is composed of thick fibrous tissue with smooth muscle fibers and a thin posterior capsule of orbital fat...

Perivascular fat, the cushion of adipose tissue surrounding blood vessels, possesses dilator, anti-contractile and constrictor actions. The majority of these effects have been demonstrated in vitro and may depend on the vessel and/or the experimental method or species used. In general, the relaxant effect of perivascular adipose tissue is local and may be either endothelium-dependent or endothelium-independent. However, nerve stimulation studies show that, in general, perivascular adipose tissue (PVAT) has an anti-contractile vascular effect likely to involve an action of the autonomic vascular nerves...

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...

BACKGROUND: Traditional and non-traditional risk factors for atherosclerotic cardiovascular disease (ASCVD) are different between men and women. Gender-linked impact of epicardial adipose tissue volume (EATV) in patients undergoing coronary artery bypass grafting (CABG) remains unknown. METHODS: Gender-linked impact of EATV, abdominal fat distribution and other traditional ASCVD risk factors were compared in 172 patients (men: 115; women: 57) who underwent CABG or non-coronary valvular surgery (non-CABG)...

Bone repair/regeneration is usually investigated through x-ray computed microtomography (μCT) supported by histology of extracted samples, to analyze biomaterial structure and new bone formation processes. Magnetic Resonance Imaging (μMRI) shows a richer tissue contrast than μCT, despite at lower resolution, and could be combined with μCT in the perspective of conducting non-destructive 3D investigations of bone. A pipeline designed to combine μMRI and μCT images of bone samples is here described and applied on samples of extracted human jawbone core following bone graft...

Autologous fat grafting is a gold standard therapy for soft tissue defects, but is hampered by unpredictable postoperative outcomes. Fat graft enrichment with adipose-derived stromal cell (ASCs) was recently reported to enhance graft survival. Platelet-rich plasma (PRP) has also emerged as a biologic scaffold that promotes fat graft viability. Combined ASC/PRP fat grafting enrichment is thus a promising new regenerative medicine approach. The effects of PRP on ASC proliferation are well documented, but the impact of PRP on ASC differentiation has yet to be investigated in depth to further elucidate the PRP clinical effects...

BACKGROUND: The use of fat grafting as a reconstructive surgical option is becoming much more common. Adipose-derived stem cells found in fat grafts are believed to facilitate wound healing via differentiation into fibroblasts and keratinocytes and the release of pro-healing growth factors. Several small studies have shown a positive effect of fat grafting in healing of wounds of a variety of aetiologies. When fat is combined with autologous platelet-rich plasma (PRP), there may be enhanced healing effects...
