BACKGROUND: Fat grafting has emerged as a reference procedure in daily plastic surgery practice. Unpredictable fat resorption is the main clinical problem. For this purpose, the addition of PRP to enhance fat revascularization is now an easy and popular procedure. However, no consensus exists regarding the respective volume of fat and PRP used to obtain the ideal mixture. This study investigated the rheological properties of microfat mixed with different proportions of PRP. Results obtained were compared with commercialized hyaluronic acid fillers...

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...

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...

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...

INTRODUCTION: External volume expansion (EVE) is one method, which has been utilised for increasing the survival of adipose tissue grafts. EVE releases positive pressure from the graft and also induces intense levels of edema that decreases diffusion of metabolites essential for graft survival initially. The ideal timing of external volume expansion in relation to the injection of the fat to facilitate survival is not yet clear. AIMS AND OBJECTIVES: This study was undertaken to evaluate and compare the efficacy of external volume expansion applied at variable time points in relation to the injection of the fat...

The ideal filler for aesthetic surgery is inexpensive and easy to obtain, natural in appearance and texture, immunologically compatible, and long lasting without risk of infection. By most metrics, autologous fat grafts meet these criteria perfectly. Although facial fat grafting is now a commonly accepted surgical procedure, there has been a wave of activity applying stem cells and platelet-rich plasma (PRP) therapies to aesthetic practice. This article addresses technical considerations in the use of autologous fat transfer for facial rejuvenation, and also explores the current evidence for these stem cell and PRP therapies in aesthetic practice...

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...

Evolving atrophic macular degeneration represents at least 80% of all macular degenerations and is currently without a standardized care. Autologous fat transplantation efficacy was demonstrated by several studies, as these cells are able to produce growth factors. The aim of the work was to demonstrate possible therapeutic effect of the joined suprachoroidal graft of adipocytes, adipose-derived stem cells (ADSCs) in stromal vascular fractions (SVFs) of adipose tissue, and platelet-rich plasma (PRP). Twelve eyes in 12 dry age-related macular degeneration (AMD) patients, aged 71...

Autologous fat transfer offers many qualities of a ideal soft tissue filler. Main advantages of fat grafting ensue from the fact that the lipoaspirate tissue is an abundant source of regenerative pluripotential cells. However, the reported rates of fat cell survival vary greatly in the medical literature (10-90%). Different techniques of harvesting, processing, and reinjecting the fat cells are so claimed to be responsible for these differences, without any agreement concerning the best way to process. To address this important disadvantage, we propose the addition of autologous platelet rich plasma (PRP) which is known as a natural reservoir of growth factors stimulating tissue repair and regeneration...

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...
