Genome wide analysis of Visceral adipose tissue CD14+ cells from Obese and obese diabetic subjects

ABSTRACT: Identification of the inflammatory signature in visceral adipose tissue CD14+ cells (adipose tissue macrophage) Total RNA obtained from CD14+ cells (Immunoselcted cells from stromal adipose tissue cells) Adipocytes and cells of the stroma vascular fraction (SVF) were obtained by collagenase digestion of adipose tissue. SVF cells were resuspended in endotoxin-free PBS supplemented with 2% FCS and 1 mM EDTA. Isolation of CD14+ using positive selection magnetic beads (Stemcell technologies) and CD4+ cells was performed using positive selection magnetic beads (Stemcell Technologies, Vancouver, Canada). An Illumina (San Diego, CA) RNA amplification kit (NuGEN, BiotinIL Module) was used according to the manufacturer's instructions to obtain biotinlabeled cDNA from 50 ng of total RNA extracted from adipose tissue CD14+ cells.

Gene expression data of brown-like adipocytes from Lgr4 homozygous mutant SVF

Project description:Obesity has become a global health problem. Brown adipose tissue (BAT), specialized for energy expenditure through thermogenesis, potently counteracts obesity. Recently, BAT is also identified in human adults. We found that Lgr4 homozygous mutant (Lgr4m/m) mice display reduced adiposity and exhibit brown-like adipocytes in their WAT depots with higher expression of uncoupling protein 1 (Ucp1). Furthermore, Lgr4 ablation potentiates brown adipocyte differentiation from stromal vascular fraction (SVF) of epididymal WAT (eWAT) in vitro. We used microarrays to emxamine the gene expression profiles of the brown-like adipocytes differentiated from SVF of wild-type and Lgr4 mutant mice. We identified distinct gene expression profiles of these two groups. To demonstrate Lgr4 ablation can potentiate the differentiation of SVF from eWAT toward brown-like adipocytes in vitro, we isolated SVF from epididymal white adipose tissue (eWAT) of wild-type (WT) and Lgr4 mutant mice. We then plated SVF cells in 12-well plate, and differentiated them to brown adipocytes, followed by RNA extraction and hybridization with Affymetrix microarrays.

Gene expression in canine adipose stromal vascular fraction

Project description:Microarray studies were performed to identify expression patterns by cryopreserved adipose stromal vascular fraction (SVF) preparations that were prepared by three different veterinary stem cell companies from the same source of canine adipose tissue. [Samples 1 - 3] Three equal samples of approximately 20 grams of adipose tissue were shipped on ice to 3 different companies which specialize in adipose-derived veterinary stem cell therapy. All 3 SVF preparations were cryopreserved at their respective facilities. Approximately one month later, cryopreserved samples were retrieved from all companies and transported frozen to the University of Kentucky for gene profiling and viability analysis. [Samples 4 - 11] Groups of cells (samples 5, 7, 9, 11) were treated by the stem cell company with photo-activated platelet-rich plasma (PRP) according to their proprietary procedures in order to enhance regenerative properties of the adipose stem cells. These PRP-treated cells were incubated in the investigator's lab for 6 hours at 37 degrees Celsius to allow for expression of genes that were induced by PRP treatment.

FACS sorting of human adipose tissue stromal vascular fraction

Project description:Adipose tissue from 6 non-obese patients was collagenase treated and adipocytes separated from the stromal vascular fraction(SVF). SVF was then FACS sorted for the following fractions CD45-/CD34+/CD31+ (endothelial), CD45-/CD34+/CD31- (progenitor), CD45+/CD14+ (monocyte/macrophage), CD45+/CD14-(Leukocyte). RNA was isolated from adipocyte, SVF, progenitor, macrophage/monocyte and leukocyte fractions and analyzed on the Affymetrix Human Transcriptome 2.0 array. We also sorted SVF from an additional 13 (10 non-obese, 9 obese) patients and sent progenitor RNA for Affymetrix Human Transcriptome 2.0 array analysis.

RNA-seq analysis of adipose tissue-derived mesenchymal stem cells (AD-MSCs) selected for the surface marker CD271 (CD271+), compared to unsorted stromal vascular fraction (US), and the CD271- AD-MSCs population (CD271-).

Project description:Differences in gene expression between unsorted adipose tissue-derived mesenchymal stem cells (AD-MSCs), and a specific subpopulation that has been selected for the expression of the surface marker CD271. It is believed that the selection of this specific subpopulation from the heterogeneous SVF will lead to mesenchymal stem cells with higher angiogenetic potential.

Transcriptome profiling of subcutaneous and visceral adipose tissue from obese individuals

Project description:Distinct characteristics of adipose tissue at different localization of human body has shown greater significance in development of metabolic disorders. Visceral adipose tissue in particular is known to be associated with obesity related metabolic complications that include type II diabetes. In this experiment, we attempt to profile transcriptome signatures of adipocyte, stromal vascular fraction (SVF) and adipose tissue from subcutaneous and visceral adipose tissue from obese individuals.

scRNA-seq of stromal vascular cells from 48 week (aged) mouse subcutaneous adipose tissue compared to control 10 week (young) mouse SVF

Project description:Adipose tissue mass and adiposity change throughout the lifespan. During aging, while visceral adipose tissue (VAT) tends to increase, peripheral subcutaneous adipose tissue (SAT) decreases significantly. Unlike VAT, which is linked to metabolic diseases, SAT has beneficial effects. However, the molecular details behind aging-associated loss of SAT remain unclear. Here we compare scRNA-seq of total SVF of SAT from young and aging mice to identify a novel Aging-dependent Regulatory Cell (ARC) that emerges in SAT of aged mice. Inguinal white adipose tissue (iWAT) was used as a representative SAT; iWAT pads of 2 mice from each age group were subjected to collagenase digestion and treated with a hypotonic buffer to remove red blood cells before subjection to scRNA-seq by 10X Genomics Chromium Single Cell Kit. The findings showed that ARCs express adipogenic markers but lack adipogenic capacity and inhibit differentiation of neighboring adipose precursors.

Single-cell RNA-seq of the human Lineage– cells derived from the adipose stromal vascular fraction across depots

Project description:We used single-cell RNA-seq to characterize the heterogeneity of the human Lin- stromal vascular fraction across five adipose depots. We mollecularly assessed Lin- SVF cells from subcutaneous, omentum, mesocolic, and perirenal fat depots, as well as gallbladder-associated fat using 10x Genomics.
