Reflective Blankets vs Electric Warming in Preventing Hypothermia During Liposuction: A Randomized Controlled Trial.
[BACKGROUND] Perioperative hypothermia is common during liposuction and can lead to delayed recovery, shivering, and patient discomfort. Although electric warming (EW) systems are effective, their use may be limited in certain settings. [O…

Attenuated Angiogenesis and Macrophage Infiltration during Adipose Tissue Regeneration in Megavolume Human Fat Grafting.
[BACKGROUND] Survival and regeneration mechanisms of large (>250 mL) fat grafts remain incompletely understood. In fat grafts from volunteers with megavolume fat transfer breast augmentation, neovascularization and inflammatory cell infiltr…

Type IV Collagen Promotes Adipogenic Differentiation of Adipose Stem Cells.
Type IV collagen is a major component of the extracellular matrix in adipose tissue. It is secreted during the lipogenic differentiation of mesenchymal stem cells, but its direct impact and mechanism on the differentiation of adipose-derive…

Pathological characteristics of breast nodules after large-volume fat grafting for breast augmentation.
[BACKGROUND] The complications of large-volume fat grafting (LVFG) for breast augmentation remain unpredictable and include palpable breast nodules, oil cysts, and calcifications. [AIMS] This study was aimed to provide an optimal treatment…
-
Alternatively activated macrophages at the recipient site improve fat graft retention by promoting angiogenesis and adipogenesis.
The inflammatory response mediated by macrophages plays a role in tissue repair. Macrophages preferentially infiltrate the donor site and subsequently, infiltrate the recipient site after fat grafting. This study aimed to trace host-derived…

Density-Based High-Quality Fat: Characterization and Correlation with Different Body Fat Ratio.
[BACKGROUND] Lipoaspirate can be divided into high-quality fat and low-quality fat using Coleman's centrifugation by adding 0.935 g/ml marker float; the ratio obtained by different individuals is different. [OBJECTIVES] This study aimed to…
-
A Preliminary Exploratory Study of Autologous Fat Transplantation in Breast Augmentation With Different Fat Transplantation Planes.
[BACKGROUND] Autologous fat transfer is common in breast augmentationor reconstruction. However, AFG recipient site in the breast for fat grafting has not been carefully investigated. [METHODS] Forty female patients requiring breast augmen…

Improving Low-Density Fat by Condensing Cellular and Collagen Content through a Mechanical Process: Basic Research and Clinical Applications.
[BACKGROUND] Large-volume fat grafting results in high absorption and complication rates. Low-density fat includes small numbers of viable cells and considerable oil, resulting in nodules and oil cysts. This study evaluated a strategy for l…

Mechanical Micronization of Lipoaspirates for the Treatment of Horizontal Neck Lines.
[BACKGROUND] Horizontal neck wrinkles develop as a result of the aging process. Stromal vascular fraction (SVF) gel, which is rich in extracellular matrix and functional cells, can be produced by a series of simple mechanical processes, inc…

Botulinum Toxin A Improves Supramuscular Fat Graft Retention by Enhancing Angiogenesis and Adipogenesis.
[BACKGROUND] Autologous fat grafting is commonly used for soft-tissue augmentation and reconstruction in plastic surgery. However, long-term graft retention rates are unpredictable, especially in muscle-related fat grafting. [OBJECTIVE] To…

The effects of macrophage-mediated inflammatory response to the donor site on long-term retention of a fat graft in the recipient site in a mice model.
Inflammatory responses mediated by macrophages play a role in tissue repair. However, it is unclear whether the repair in the donor site after liposuction would have any effects on fat graft retention in the recipient site. This study is de…

Fat Grafting for Facial Rejuvenation Using Stromal Vascular Fraction Gel Injection.
This study used stromal vascular fraction gel (SVF-gel), a mechanically processed fat-derived product, to treat eye bag and tear trough deformity. SVF-gel is prepared by a process of centrifugation and intersyringe shifting and is particula…

Biocompatible Interface-Modified Tissue Engineering Chamber Reduces Capsular Contracture and Enlarges Regenerated Adipose Tissue.
Adipose flap expansion using a tissue engineering chamber (TEC) presents a promising candidate for soft tissue regeneration by activating in situ adipose tissue regeneration. However, foreign body reaction (FBR) and capsular contracture cau…

Three-dimensional printing of facial contour based on preoperative computer simulation and its clinical application.
Facial contouring is a complex procedure performed to alter tissue contents and restore facial appearance. However, it is difficult to measure the amount of the tissue volume that is needed. This study demonstrated the use of preoperative c…

HGF-induced formation of the MET-AXL-ELMO2-DOCK180 complex promotes RAC1 activation, receptor clustering, and cancer cell migration and invasion.
The proto-oncogene-encoded receptor tyrosine kinase (MET) and AXL receptor tyrosine kinase (AXL) are independently operating receptor tyrosine kinases (RTKs) that are functionally associated with aggressive and invasive cancer cell growth.…

A Modified Double Eyelid Plastic Surgery Method: Continuous Buried Suture Method Accompanied by Simultaneous Correction of Mild Blepharoptosis.
[BACKGROUND] Double eyelid surgery with a buried suture is a popular plastic surgery procedure in Asia owing to the relatively minor scarring and quick recovery associated with it. In this article, we present a new approach involving a cont…
-
Macrophage infiltration regulates the adipose ECM reconstruction and the fibrosis process after fat grafting.
[BACKGROUND] Fat grafting experiences a regeneration process from free lipoaspirate to intact adipose tissue. The adipose extracellular matrixes (ECM) provide the structure and biochemical support for surrounding cells; inflammatory cells, …

Adipocyte regeneration after free fat transplantation: promotion by stromal vascular fraction cells.
Our objective was to explore the mechanism of cell-assisted adipose transplantation by using freshly isolated human stromal vascular fraction (SVF) cells and to observe the dynamic changes of the graft after transplantation. The SVF was iso…

In vivo injectable human adipose tissue regeneration by adipose-derived stem cells isolated from the fluid portion of liposuction aspirates.
Liposuction aspirates separate into fatty and fluid portions. Cells isolated from the fatty portion are termed processed lipoaspirate (PLA) cells and isolated from the fluid portion termed liposuction aspirate fluid (LAF) cells, both of whi…
