Project description:Scope: Adipose tissue is regarded as a true endocrine organ. Recent studies showed that adipose tissue derived exosomes could serve as carrier of circulating miRNAs to regulate distant targets. However, the characteristics of exosomal proteins released from adipose tissue have not been investigated yet. Methods and Results: In this study, we conducted a complementary protein profiling on exosome-like vesicles derived from adipose tissue (ELV-AT) with Label-free Quantitative Proteomic Analysis. A total of 3229 ELV-AT proteins were identified, among which only 266 proteins have been annotated as adipokines. 3 undefined adipokine candidates (NPM3, STEAP3, and DAD1) were selected for further validation. These 3 proteins were expressed in both white and brown adipose tissue, upregulated during adipogenic differentiation of both 3T3-L1 cells and adipose derived stem cells (ADSCs). Expressions of NPM3, DAD1 in ELV-AT were significantly decreased in obese subjects compared with lean controls while obesity could not alter the expression of STEAP3. Conclusions: Our profiling study of the ELV-AT proteins expands the list of adipokines and highlights the pivotal role of exosomal adipokines in the regulation of multiple biological processes within adipose tissue

Project description:Directed differentiation of cells in vitro is a powerful approach for dissection of developmental pathways, disease modeling and regenerative medicine, but analysis of such systems are complicated by heterogeneous and asynchronous cellular responses to differentiation-inducing stimuli. To enable deep characterization of heterogeneous cell populations, we developed an efficient digital gene expression profiling protocol that enables surveying of mRNA in thousands of single cells at a time. We then applied this protocol to profile 11,116 cells collected during directed differentiation of human adipose-derived stem/stromal cells. The resulting data reveals the major axes of cell-to-cell variation within and between time points and suggests a link between incomplete adipogenesis in vitro and adipocyte dysfunction in vivo.

Project description:human Multipotent Adipose-Derived Stem (hMADS) cells were subjected to adipogenic differentiation in vitro and microRNA expression was analyzed during differentiation. Total RNA was extracted at day 0 (AD0), day 3 (AD3) and day 8 (AD8) of differentiation, two biological replicates (1) and (2), and microRNA profiles were established with SOLiD sequencing.

Project description:Background: Obesity is characterized as a disease that directly affects the whole-body metabolism and is associated with excess fat mass and several related comorbidities. Dynamics of the adipocyte hypertrophy and hyperplasia play an important role in health and disease, especially in obesity. Human adipose-derived stem cells (hASC) represent an important source for understanding the entire adipogenic differentiation process. However, little is known about the triggering step of adipogenesis in hASC. Here, we performed a proteogenomic approach for understanding the protein abundance alterations expression changes during the initiation of the adipogenic differentiation process. Methods: hASC were isolated from adipose tissue from three donors, characterized and expanded. Cells were cultured for 24 hours in adipogenic differentiation medium followed to protein extraction. We used shotgun proteomics to compare the proteomic profile of 24h-adipogenic differentiated and undifferentiated hASC. Besides, we used our previously next-generation sequencing data (RNA-seq) from the total and polysomal mRNA fractions of hASC to study post-transcriptional regulation during the initial steps of adipogenesis. Results: We identified a total of 3,.420 proteins out of and 48,.336 peptides, being 92 exclusively identified proteins in the undifferentiated hASC and 53 exclusive proteins in 24h-differentiated cells. Using a stringent criterion, we identified 33 differentially abundant proteins when compare 24h-differentiated versus undifferentiated hASC (14 upregulated and 19 downregulated, respectively). Among the upregulated proteins, we shortlist identified several adipogenic-related proteins. Combined analysis of the proteome and the transcriptome allowed the identification of positive correlation coefficients between proteins and mRNAs. Conclusions: These results demonstrate a specific proteome profile related to adipogenesis at the very beginning (24h) of the differentiation process in hASC, which represents an important piece for a better understanding of human adipogenesis and obesity. In addition, the adipogenic differentiation is fine-tuning regulated at transcriptional, post-transcriptional and post-translational levels.

Project description:Analysis of human adipose tissue-derived stem cells (hMADS cells) overexpressing either miR-30a or miR-30d, as well as knocked-down for the whole miR-30 family. Gene expression was analyzed after 4 days in adipogenic medium. Data give insight into the role of miR-30 during adipogenesis, and identifies enriched predicted targets for miR-30. Human adipose tissue-derived stem cells (hMADS cells) were transfected with one of the following: premiR-30a (Ambion), premiR-30d (Ambion), premiR negative control #1 (Ambion). Three days after transfection, cells were submitted to adipogenic differentiation for 4 days. In a separate experiment, hMADS cells were transfected with either antimiR-30 or antimiR-neg (mismatch control), and then submitted to differentiation as described above. For each experimental condition, 2 hMADS cell clones were used independently (clone B7 and B9).

Project description:Pathological processes like osteoporosis or steroid-induced osteonecrosis of the hip are accompanied by increased bone marrow adipogenesis. Such disorder of adipogenic/osteogenic differentiation, which affects also bone marrow derived mesenchymal stem cells (BMSCs) contributes to bone loss during aging. Therefore, we investigated the effects of extracellular vesicles (EVs) isolated from human (h)BMSCs during different stages of osteogenic differentiation on osteogenic and adipogenic differentiation capacity of naïve hBMSCs.

Project description:Adipose-derived and bone-marrow-derived mesenchymal stem cells were collected from 3 pigs and cultivated in vitro up to 3 passages. At passage 3 cells were cultured to 80% confluence and induced to differentiate in adipose and bone. Cell were harvested at 0 day of differentiation (dd) or pre-differentiation, at 2, 7, and 21dd for RNA extraction. The RNA was used for a large microarray analysis using a specific pig oligo-array with >10,000 annotated genes. The main aim of the microarray analysis was to directly compare the two transcriptomics adaptation of the two mesenchymal stem cells during osteogenic and adipogenic differentiation The mesenchymal stem cells were harvested at 0, 2, 7, and 21 day of differentiation (dd). A dye-swap reference design (reference = mixture of RNA from several porcine tissues) was used.
