Oestrogen receptor 2 () expression has been shown to be higher in subcutaneous adipose tissue (SAT) from postmenopausal compared to premenopausal women. The functional significance of altered expression is not fully known. This study investigates the role of for adipose tissue lipid and glucose metabolism. SAT biopsies were obtained from 44 female subjects with or without T2D. Gene expression of and markers of adipose function and metabolism was assessed. knockdown was performed using CRISPR/Cas9 in preadipocytes isolated from SAT of females, and differentiation rate, lipid storage, and glucose uptake were measured. expression was inversely correlated with measures of central obesity and expression of some fatty acid oxidation markers, and positively correlated with lipid storage and glucose transport markers. Differentiation was reduced in knockdown preadipocytes. This corresponded to reduced expression of markers of differentiation and lipogenesis. Glucose uptake was reduced in knockdown adipocytes.Our results indicate that deficiency in women is associated with visceral adiposity and impaired subcutaneous adipocyte differentiation as well as glucose and lipid utilization. High expression, as seen after menopause, could be a contributing factor to SAT expansion. This may support a possible target to promote a healthy obesity phenotype.

Intestinal barrier damage causes an imbalance in the intestinal flora and microbial environment, promoting a variety of gastrointestinal diseases. This study aimed to explore the mechanism by which adipose-derived stem cells (ADSCs) repair intestinal barrier damage. The human colon adenocarcinoma cell line Caco-2 and rats were treated with lipopolysaccharide (LPS) to establish in vitro and in vivo models, respectively, of intestinal barrier damage.

Stromal vascular fraction (SVF) is a heterogeneous collection of cells obtained from adipose tissue through lipoaspiration and is an alter-native intraarticular treatment option, especially in osteoarthritis (OA). The anti-inflammatory and extracellular tissue repair-stimulating properties of SVF increase its effectiveness in regeneration and repair mechanisms. One of the most common symptoms of hemophilia A and B is hemophilic arthropathy (HA).

Objective: Exosomes (Exos) from adipose derived stem cells (ADSCs) can delay skin photoaging, but their effects on reactive oxygen species (ROS) remains unclear. This study aimed to investigate the relationship between adipose derived stem cell exosomes (ADSCs-Exos) in anti-photoaging of skin and glutathione (GSH)/ ROS expression in human fibroblasts.
Methods: A skin photoaging model was established by irradiating human fibroblasts with ultraviolet B (UVB) light in vitro.

Lifestyle-related diseases, such as atherosclerosis and diabetes, are now considered to be a series of diseases caused by chronic inflammation. Adipose tissue is considered to be an endocrine organ that not only plays a role in lipid storage, heat production, and buffering, but also produces physiologically active substances and is involved in chronic inflammation. Perivascular adipose tissue (PVAT) surrounding blood vessels similarly produces inflammatory and anti-inflammatory physiologically active substances that act on blood vessels either directly or via the bloodstream.

Introduction: Systemic administration of induced pluripotent stem cell-derived mesenchymal stem cells (iPS-MSCs) has a therapeutic effect on myocardial ischemia. However, the therapeutic mechanism underlying systemic iPS-MSC-based therapy for ischemic cardiomyopathy (ICM) remains unclear. We investigated the therapeutic effects of iPS-MSCs through extracellular vesicle (EV)-mediated tissue repair in a rat model of ICM.
