In healthy blood vessels, albumin crosses the endothelium to leave the circulation by transcytosis. However, little is known about the regulation of albumin transcytosis or how it differs in different tissues; its physiological purpose is also unclear. Using total internal reflection fluorescence microscopy, we quantified transcytosis of albumin across primary human microvascular endothelial cells from both lung and skin. We then validated our in vitro findings using a tissue-specific knockout mouse model. We observed that albumin transcytosis was saturable in the skin but not the lung microvascular endothelial cells, implicating a receptor-mediated process...

Oncoplastic breast surgery (OBS), which combines the concepts of oncologic and plastic surgery, is becoming more common worldwide. We report the results of OBS in a Japanese patient with early breast cancer located on the outer lower quadrant area. We performed OBS combining partial mastectomy with immediate breast reshaping using multiple adipofascial cutaneous flaps and free dermal fat graft because she refused any other OBS. We selected three local flaps to repair the defect. Perioperative and postoperative complications were not seen...

BACKGROUND: Hypertrophic scars cause cosmetic and functional problems for patients, and their treatment remains challenging. Mechanical micronization of adipose tissue can remove adipocytes and concentrate functional cells. Stromal vascular fraction (SVF)-gel is obtained by a series of simple mechanical processes, including shifting between syringes and centrifugation. This study aimed to assess the therapeutic effect of SVF-gel on hypertrophic scars. METHODS: A model of hypertrophic scars was established in rabbit ears...

BACKGROUND & AIMS: Anorexia nervosa (AN) is a severe psychosomatic disease that seriously affects nutritional status. Therapeutic approaches primarily aim for rapid weight restoration by high caloric diets and activity restriction. This often promotes abdominal body fat gain, which potentially negatively influences the patient's compliance and increases the risk of relapse. This study focused on the evaluation of body weight and subcutaneous adipose tissue (SAT) in AN patients by novel approaches...

PURPOSE: Robotics has evolved rapidly in terms of mechanical design and control in the past few years. Collaborative robots that have direct contact with humans are being introduced in various fields, including industrial and medical services. Because collaborative robot systems are being introduced rapidly, the safety of the humans who work with them is becoming an important issue. In this study, we investigated skin injuries resulting from a collision between robots and humans using a freefall experiment system...

BACKGROUND: Frontal fibrosing alopecia (FFA) is an irreversible scarring alopecia, and its incidence has reached epidemic size. Immune privilege collapse of the bulge and epithelial mesenchymal transition play a role in the pathogenesis. We have noted adipose tissue in the dermis in several specimens from FFA. OBJECTIVE: Our primary objective was to verify the presence of adipose tissue at the isthmus level in biopsies from FFA. Additional objectives included the presence of deep inflammation and position of the sweat coils...

AIMS: Histopathologic overlap between lupus erythematosus and certain types of cutaneous T-cell lymphoma (CTCL) is well documented. CD123+ plasmacytoid dendritic cells (PDCs) are typically increased in lupus erythematosus, but have not been well studied in CTCL. We aimed to compare CD123 immunostaining and histopathologic features in these conditions. METHODS AND RESULTS: Skin biopsies of cutaneous lupus erythematosus (CLE, n=18), lupus erythematosus panniculitis (LEP, n=17), mycosis fungoides (MF, n=25) and subcutaneous panniculitis-like T-cell lymphoma (SPTCL, n=9) were retrospectively reviewed and immunostained with CD123...

Dermal fibroblasts (dFBs) resist infection by locally differentiating into adipocytes and producing cathelicidin antimicrobial peptide in response to Staphylococcus aureus (S. aureus). Here, we show that neonatal skin was enriched with adipogenic dFBs and immature dermal fat that highly expressed cathelicidin. The pool of adipogenic and antimicrobial dFBs declined after birth, leading to an age-dependent loss of dermal fat and a decrease in adipogenesis and cathelidicin production in response to infection...

INTRODUCTION: Reconstruction of segmental peripheral nerve gap is still challenging when the autografts are unavailable owing to limited availability of donor site and functional recovery. The creation of artificial conduits composed of biological or synthetic materials is still developing. Acellular dermal matrix (ADM) has been widely studied and its extension and plasticity properties may become suitable nerve conduits under different forms of nerve gaps. Adipose-derived stem cells (ADSCs) have the potential to differentiate into various cell types of different germ layers including neural stem cells (NSCs)...

A 3-dimensional, multi-layered approach combining modalities targeting different manifestations is recommended for achieving optimal esthetic outcomes. To date, studies reporting same-day treatment with dermal fillers and botulinum toxin have not been published. This article documents the practical use of a single-visit, pan-facial multimodal approach in addressing the varying esthetic needs of 8 Asian adults. The case series included male or female patients of varying age and degrees of facial fat, who received combination treatment with calcium hydroxylapatite filler, polydensified hyaluronic acid filler, and incobotulinumtoxin A in a single visit in August 2016 at a treatment center in Taiwan...

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...

RATIONALE: Limbal dermoids are choristomas known as congenital benign tumors found in abnormal locations. Despite the benign nature, enlarging limbal dermoids may cause visual abnormalities by cornea infiltration with fat component, visual axis invasion, gradually induced corneal astigmatism, and finally result in anisometropic amblyopia. Here we report a rare case of progressive, large pediatric corneal limbal dermoid in a newborn, managed with tissue glue-assisted monolayer amniotic membrane transplantation...

During aging, stromal functions are thought to be impaired, but little is known whether this stems from changes of fibroblasts. Using population- and single-cell transcriptomics, as well as long-term lineage tracing, we studied whether murine dermal fibroblasts are altered during physiological aging under different dietary regimes that affect longevity. We show that the identity of old fibroblasts becomes undefined, with the fibroblast states present in young skin no longer clearly demarcated. In addition, old fibroblasts not only reduce the expression of genes involved in the formation of the extracellular matrix, but also gain adipogenic traits, paradoxically becoming more similar to neonatal pro-adipogenic fibroblasts...

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...

In a large scale screen for skin, hair, and nail abnormalities in null mice generated by The Jackson Laboratory's KOMP center, homozygous mutant Far2tm2b(KOMP)Wtsi/2J (hereafter referrred to as Far2-/-) mice were found to develop focal areas of alopecia as they aged. As sebocytes matured in wildtype C57BL/NJ mice they became pale with fine, uniformly sized clear lipid containing vacuoles that were released when sebocytes disintegrated in the duct. By contrast, the Far2-/- null mice had sebocytes that were similar within the gland but become brightly eosinophilic when the cells entered the sebaceous gland duct...

Linear scleroderma en coup de sabre (LScs) is a variant of localized scleroderma. This disease typically occurs in patients in their 20s or younger individuals and predominantly occurs in the forehead area. A 26-year-old man with linear scleroderma was surgically treated at our center with Medpor (porous polyethylene) and dermal fat graft for the forehead lesion. After 26 months of postoperative follow-up, the depressed lesion that appeared scarred as well as the margins improved significantly. The surgical treatment of LScs using Medpor and dermal fat graft is an effective treatment modality that can increase patient satisfaction...
