Project description:Molecular profiling of human bone marrow and adipose tissue-derived stromal cells

Project description:Limbal stromal cells were reported to resemble mesenchymal stem cells (MSCs) with multipotential differentiation cability. However, little is known about their gene expression profiles compared to MSC derived from various sources. In this study, the gene expression profile of limbal stromal cells was compared to bone marrow, adipose stromal cells and foreskin fibroblasts. In addition, we also explored the gene expression changes of ex vivo expanded limbal stromal cells when cultured in two different systems. Expanded limbal stromal cells were divided into two groups; each cultured separately on a matrigel-coated plate in DMEM/F12 medium supplemented with bFGF and LIF and the other on a normal plate in DMEM medium supplemented with 10% fetal bovine serum (FBS). Cryopreserved bone marrow mesenchymal cells, adipose stromal cells and foreskin fibroblasts were cultured-expanded until confluent. Total RNA was extracted from all the samples and subjected to microarray experiments with an Agilent platform by using Human GE 8x60k microarrays. Data analysis was carried out with GeneSpring software. A total of 871 genes were upregulated when the limbal stromal cells were cultured in the matrigel system, whereas 58 genes were consistently differentially expressed in limbal stromal cells compared to other lineages. Besides the long intergenic non-coding RNA and unknown genes, these genes represent gene ontology for cellular components, molecular function and biological process. Samples derived from the same source were closely clustered by Hierachical clustering analysis. The limbal stromal cells have a distinct molecular signature compared to MSCs from other lineages. The culture system affected the gene expression profile of limbal stromal cells tremendously. Derived limbal stromal cells were cultured using two different methods, one with matrigel and the other with FBS. Their gene expression profiles were compared. The gene expression profile of limbal stromal cells that were cultured with FBS also was compared to the gene expression profiles of bone marrow mesenchymal stem cells, adipose stromal cells and foreskin fibroblasts.

Project description:Mesenchymal stem/stromal cells (MSCs) were harvested from subcutaneous adipose tissue of patients with obesity or healthy controls and expanded for 3-4 passages, and 5hmC profiles were examined through hydroxymethylated DNA immunoprecipitation sequencing (hMeDIP-seq). We hypothesized that obesity and cardiovascular risk factors induce functionally-relevant, locus-specific changes in overall exonic coverage of 5hmC in human adipose-derived MSCs.

Project description:We used an in vitro model to study the paracrine effect of stromal cells isolated from omental adipose tissue at different stages of differentiation and inflammation on the beta cell lines EndoC-βH1 through the use of conditioned media. We show that the expression of beta cells markers decreased and dedifferentiation markers increased when beta cells were cultured in conditioned medium derived from omental stromal cells. We report that stromal cells with a high pro-inflammatory profile had the most severe impact. By using RNAseq, we showed the stimulation of several signaling pathways such as STAT3, SMAD2 and RELA, as well as the downregulation of genes involved in lipogenesis and cholesterol synthesis.

Project description:To identify candidates of interest that were more highly expressed in BAT than WAT, we conducted RNAseq in human primary brown and white adipocytes. Adipose tissue was obtained from the central compartment of the neck, superior to the clavicle and deep to the lateral thyroid lobe either adjacent to the longus colli muscle or to the oesophagus (brown adipose tissue) and more superficially from the subcutaneous neck tissue (white adipose tissue). The stromal vascular fraction was isolated and cultured as described (Ramage, Akyol et al. 2016 doi: 10.1016/j.cmet.2016.06.011). Following differentiation, cells were cultured in serum-stripped medium for 48 hours prior to RNA extraction and subsequent bulk RNA-seq.
