Cell-assisted lipotransfer has shown much promise as a technique to improve fat graft retention in both mouse and human studies. However, the literature varies as to whether fresh stromal vascular fraction or culture-expanded adipose-derived stromal cells are used to augment volume retention. The authors' study sought to determine whether there was a significant advantage to using adipose-derived stromal cells over unpurified stromal vascular fraction cells in a mouse model of cell-assisted lipotransfer.

BACKGROUND: Intermittent external volume expansion using suction enhances the vascular network of soft tissues, possibly increasing fat graft survival. However, the optimal kinetics of application have not been determined. Based on their previous experience, the authors hypothesized that moderate-intensity intermittent external volume expansion application may further enhance both the angiogenic and adipogenic potential. METHODS: Fifty 12-week-old wild-type mice were assigned to five experimental groups (n = 10 per group) and underwent five different intermittent applications of external volume expansion (i...

Breast implants and, more recently, autologous fat grafting are the two most common treatments used to correct tuberous breast deformity (TBD). The post-surgical quality of life between the two techniques is not well demonstrated. This study aimed to compare satisfaction and health-related quality of life in patients affected by TBD between these two techniques. All TBD patients operated between January 2008 and May 2015 were retrospectively identified, and only those treated with implants or lipofilling were included...

BACKGROUND: Cancer cells are typically surrounded by stromal cells and embedded in extracellular matrix (ECM). The stromal compartment interacts with cancer cells to promote growth and metastasis. For decades, autologous fasciocutaneous flaps have been safely applied for breast reconstruction after mastectomy. In contrast, the safety of fat grafting (lipofilling) procedure has been under debate regarding the risk of cancer recurrence. METHODS: Harvested fat tissue (lipoaspirates) and dissected abdominal fat (DAF) were co-cultured with MCF-7 breast cancer cells...

BACKGROUND: For steatotic livers, pharmacological approaches to minimize the hepatic neutrophil and macrophage infiltration, and cytokine and chemokine release in ischemia-reperfusion (IR) injury are still limited. Tumor necrosis factor (TNF)-α superfamily-stimulated pathogenic cascades and M1 macrophage/Kupffer cells (KC) polarization from Th1 cytokines are important in the pathogenesis of IR liver injury with hepatic steatosis (HS). Conversely, anti-inflammatory M2 macrophages produce Th2 cytokine (interleukin-4), which reciprocally enhances M2 polarization...

BACKGROUND: Liposuction and subsequent autologous fat grafting have become essential techniques for fat augmentation in plastic surgery. However, standard harvesting techniques that ensure the survival of adipocytes and stromal vascular fraction (SVF) cells and thus preserve the transplanted fat volume are lacking. In particular, the effect of different parameters of the tumescent solution has not been studied in this context. We hypothesized that the osmolality of the tumescent solution could have a significant effect on the survival of adipocytes and SVF cells...

PURPOSE: To compare the outcomes achieved with eminectomy, discectomy alone, and discectomy with an abdominal dermis fat graft (D + ADFG) in the treatment of internal derangements (IDs) of the temporomandibular joint (TMJ), and to briefly discuss the failed cases in which a second operation was needed. PATIENTS AND METHODS: This was a retrospective study of 31 patients (27 females, 4 males) who were unresponsive to conservative therapy and therefore underwent eminectomy (group A, n = 6), discectomy alone (group B, n = 8), or D + ADFG (group C, n = 17)...

INTRODUCTION: The integrity of the palatal mucosa can be lost due to congenital, pathological, and iatrogenic conditions. Various surgical techniques have been suggested for the closure of palatal defects. The aim of the current study is to present the free buccal fat pad graft as a novel technique to repair the soft-tissue defects at the palate. PATIENTS AND METHODS: During a 2-year period, the free fat tissue graft harvested from the buccal fat pad (BFP) (FBFG) and used to reconstruct five soft-tissue defects of the palate in five patients (2 women, 3 men; mean age, 34 years; range, 22-58 years)...

Autologous fat grafting for blepharoplasty-induced lower eyelid retraction offers potential for a long-term solution while avoiding the morbidity associated with posterior lamellar spacer grafts. By combining traditional methods of lifting the retracted lower eyelid with autologous fat grafting, both functional and aesthetic concerns can be successfully addressed in these patients.

BACKGROUND: Adipose tissue-derived mesenchymal stem cells (ATMSCs) are currently used in grafting procedures in a number of clinical trials. The reconstructive role of such cells in fat graft enrichment is largely unclear. This study was undertaken to assess survival and inflammatory response in fat grafts enriched with ATMSCs in mice. METHODS: ATMSC-enriched adipose tissue was grafted subcutaneously in a clinically relevant manner in mice, and survival and inflammatory response were determined by bioluminescence imaging of transgenic tissue constitutively expressing luciferase or driven by inflammation in wild-type animals...

Many congenital and acquired defects occur in the maxillofacial area. The buccal fat pad flap (BFP) is a simple and reliable flap for the treatment of many of these defects because of its rich blood supply and location, which is close to the location of various intraoral defects. In this article, we have reviewed BFP and the associated anatomical background, surgical techniques, and clinical applications. The surgical procedure is simple and has shown a high success rate in various clinical applications (approximately 90%), including the closure of oroantral fistula, correction of congenital defect, treatment of jaw bone necrosis, and reconstruction of tumor defects...

BACKGROUND: There are several methods available for measuring breast volume in the clinical setting, but the comparability and accuracy of different methods is not well described. The ideal breast volume measurement technique should be low cost, comfortable for the patient, have no ionizing radiation and be non-invasive. METHODS: Prospective cohort study comparing a 3-dimensional (3D) laser scanner versus noncontrast magnetic resonance imaging (MRI) for breast volume assessment...

BACKGROUND: Autologous fat grafts and adipose-derived stem cells (ASCs) can be used to treat soft tissue defects. However, the results are inconsistent and sometimes comprise tissue resorption and necrosis. This might be due to insufficient vascularization. Platelet-rich plasma (PRP) is a source of concentrated autologous platelets. The growth factors and cytokines released by platelets can facilitate angiogenesis. The simultaneous use of PRP might improve the regeneration potential of fat grafts...

Aging changes to the lower eyelids and midface include pseudoherniated orbital fat, tear trough deformity, lid laxity, and dermatochalasis. Surgical repair often aims at treating redundant skin or orbital fat malposition with a lower eyelid blepharoplasty. Either a transcutaneous or transconjunctival approach may be used, though recent trends have favored the transconjunctival technique if procedures require more than simple skin excision. In manipulating the inferior orbital fat pads, a surgeon has many options including excision, repositioning, or augmentation with synthetic dermal filler, autologous fat grafts, or acellular dermal allografts...

Adipocyte-derived VEGF-A plays a crucial role in angiogenesis and contributes to adipocyte function and systemic metabolism, such as insulin resistance, chronic inflammation and beigeing of subcutaneous adipose tissue. Utilizing a doxycycline (Dox)-inducible adipocyte-specific VEGF-A overexpressing mouse model, we investigated the dynamics of local VEGF-A effects on tissue beiging of adipose tissue transplants. VEGF-A overexpression in adipocytes triggers angiogenesis. We also observe a rapid appearance of beige fat cells in subcutaneous white adipose tissue (sWATs) within as early as 2 days post induction of VEGF-A...

INTRODUCTION: Watertight reconstruction to separate the intradural compartment from the sinonasal cavities is crucial after endoscopic resection with transnasal craniectomy (ERTC) for naso-ethmoidal tumors. Three-layer reconstruction with the iliotibial tract (TRITT) is a safe and reliable alternative when vascularized flaps are not available. SURGICAL TECHNIQUE: The iliotibial tract graft is harvested on the lateral aspect of the thigh and divided in three portions, which are positioned in a multi-layered fashion to close the skull base defect...

BACKGROUND: The applications for fat grafting have increased recently, within both regenerative and reconstructive surgery. Although fat harvesting, processing and injection techniques have been extensively studied and standardised, this has not had a big impact on the variability of outcome following fat grafting. This suggests a possible larger role of patient characteristics on adipocyte and adipose-derived stem cell (ADSC) viability and function. This systematic review aims to collate current evidence on the effect of patient factors on adipocyte and ADSC behaviour...
