Project description:Adipogenesis participates in many physiological and pathological processes such as obesity and diabetes, and is regulated by a series of precise molecular events. However, the molecules involved in this regulation have not been fully characterized. We used microarrays to detail the full transcriptome expression profiles of undifferentiated and adipogenic-induced ADSCs.

Project description:Adipogenesis occurs through a specific gene program in undifferentiated fat progenitors. We hypothesized that the properties of the fat progenitors are regulated by hox genes, the developmental genes essential in different tissue stem cells. Their biased expression in white and brown fat implies roles in distinguishing the two fat types. Among 39 Hox genes, Hoxc8 is highly enriched in undifferentiated adipose tissue stem cells (ADSCs) and down-regulated in differentiated adipocytes. Forced expression of Hoxc8 suppressed adipocyte differentiation of ADSCs. Using microarrays, we investigated the effect of Hoxc8 overexpression on global transcripts in ADSCs. We compared among four groups: untreated ADSCs, adipogenic induction media (MDI)-treated ADSCs, MDI-treated ADSC-vector and MDI-treated ADSC-Hoxc8. A number of, but not all, adipogenesis-related genes are suppressed by Hoxc8. This dataset illustrates the global effect of Hoxc8, a developmental transcription factor, on the expression of adipogenesis-related genes. Gene expression was compared among untreated ADSCs (control), adipogenic induction media-treated ADSCs, adipogenic induction media-treated ADSC-vector (ADSCs transduced with control vector), and adipogenic induction media-treated ADSC-Hoxc8 (ADSCs transduced with human Hoxc8). Total RNA was isolated from ADSCs using the Qiagen RNeasy kit (Qiagen). At NimbleGen, quality and yield were verified before cDNA synthesis and Cy3-end labeling. The labeled cDNA samples were hybridized to Homo sapiens 4-Plex arrays (Roche NimbleGen, A4487001-00-01) that represent 24,000 human genes. Raw data files for each sample were normalized and background-corrected using a Robust Multi-Array Analysis as implemented by NimbleScan software. Students’ two-tail t-tests were conducted among the samples for each transcript and fold-change was determined. Transcripts whose abundance was significantly altered (P < 0.05) and an absolute fold change greater than 2 were defined as differentially regulated.

Project description:Gene Expression analysis of a differentiation timeseries of human Mesenchymal Stem Cells (hMSCs) in the presence of adipogenic/osteogenic factors. hMSCs differentiate into fat cells when treated with dexamethasone (10^-6 M), insulin (10 ug/ml), rosiglitazone (10^-7 M) and IBMX (250 uM). TGFbeta (5 ng/ml) inhibits this process and redirects these cells to differentiate into bone cells. Introduction: Patients suffering from osteoporosis show an increased number of adipocytes in their bone marrow, concomitant with a reduction in the pool of human mesenchymal stem cells (hMSCs) that are able to differentiate into osteoblasts, thus leading to suppressed osteogenesis. Methods: In order be able to interfere with this process, we have investigated in vitro culture conditions whereby adipogenic differentiation of hMSCs is impaired and osteogenic differentiation is promoted. By means of gene expression microarray analysis, we have investigated genes which are potential targets for prevention of fat cell differentiation. Results: Our data show that BMP2 promotes both adipogenic and osteogenic differentiation of hMSCs, while TGFβ inhibits differentiation into both lineages. However, when cells are cultured under adipogenic differentiation conditions, which contains cAMP-enhancing agents such as IBMX of PGE2, TGFβ promotes osteogenic differentiation, while at the same time inhibiting adipogenic differentiation. Gene expression and immunoblot analysis indicated that cAMP-induced suppression of HDAC5 levels plays an important role in the inhibitory effect of TGFβ on osteogenic differentiation. By means of gene expression microarray analysis, we have investigated genes which are downregulated by TGFβ under adipogenic differentiation conditions and may therefore be potential targets for prevention of fat cell differentiation. We thus identified 9 genes for which FDA-approved drugs are available. Our results show that drugs directed against the nuclear hormone receptor PPARG, the metalloproteinase ADAMTS5 and the aldo-keto reductase AKR1B10 inhibit adipogenic differentiation in a dose-dependent manner, although in contrast to TGFβ they do not appear to promote osteogenic differentiation. Conclusions: The approach chosen in this study has resulted in the identification of new targets for inhibition of fat cell differentiation, which may not only be relevant for prevention of osteoporosis, but also of obesity. hMSCs were induced to differentiate in the presence dexamethasone, insulin and rosiglitazone, to which was added either 50 ng/ml BMP2; BMP2 + TGFbeta; BMP2 + IBMX; BMP2 + TGFbeta + IBMX.

Project description:To further understand mechanisms governing adipogenic fate commitment, we perform a time course transcriptomic study of progenitors at 0, 3, 7 and 14 days post adipogenic induction. The progenitor cells undergo large scale gene expression changes within 3 days of exposure to adipogenic induction and adiponectin expression is strongly induced at day 3. The early detection of ADIPOQ expression suggests fate commitment occurs within 3 days of induction.

Project description:While the accumulation of bone marrow adipose tissue has been positively associated with aging and high fat diet, the physiological consequences are mostly unknown. It is well established that osteogenic and adipogenic progenitors share a common developmental origin.Unfavorable microenvironmental changes may bias these cell populations towards an adipogenic fate, which in turn could negatively influence bone homeostasis. Our previously collected data from mice reveal a high plasticity of the mesenchymal osteo-adipogenic stem cell population. Therefore, we now wish to perform by RNA-seq in defined cell population with varying adipogenic commitment within this heterogeneous stem cell pool.This data is part of a pre-publication release.
