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:The emerging evidences support that exosome cargo miRNAs function as important regulators in cell differentiation. Therefore, in order to figure out the mechanism that Exo-AT mediated adipogenesis, we profiled miRNAs in Exo-AT using high-throughput sequencing (miRNA-seq). After trimming low-quality reads, contaminants, adaptors, and reads smaller than 15 nt, the remaining reads were mapped to merged pre-miRNA data bases. To identify the conserved miRNAs in Exo exosomes, miRNAs were aligned to miRBase v21. 148 and 154 types of known miRNAs in Exo-ADSCs and Exo-AT, respectively, were identified in the two replicates. Among these miRNAs, 103 miRNAs were simultaneously detected in both Exo-ADSCs and Exo-AT. Compared to Exo-ADSCs, 45 conserved miRNAs were enriched (expressed ≥ 2 folds, FDR<0.05) in Exo-AT. KEGG Pathway analysis was performed for the targets of the most 20 enriched miRNAs in Exo-AT (compared with Exo-ADSCs) to determine their potential function. Data showed that pathways that regulate adipogenesis such as Wnt signaling pathway, Insulin signaling pathway, MAPK signaling pathway, TGF-ß signaling pathway were enriched significantly for targets of Exo-AT miRNAs. Furthermore, 14 of 45 enriched miRNAs in Exo-AT (31.11%, such as miR-30a-5p, miR-148a-3p) were reported to participate in regulation of adipogenesis while 8 miRNAs (17.78%, such as miR-93-5p, miR-150-3p) that negatively control osteoblastic differentiation of MSC have been described.

Project description:Background: Adipose-derived stem cells (ADSCs) can differentiate into Schwann cells (SCs) at the site of nerve injury, where Schwann cell-derived exosomes (SC-Exos) are suspected to exert an induction effect. Our study aimed to induce the differentiation of ADSCs in vitro using SC-Exos and to investigate the mechanisms involved through miRNA sequencing. Methods: Subcutaneous fat was used to extract ADSCs. Exosomes were extracted from Schwann cell lines (RSC96) using ultracentrifugation. After 8 days of induction of ADSCs by SC-Exos, phenotypic characteristics were observed by examining the expression of SC markers (S100, NGFR, MPZ, GFAP) through RT-qPCR, Western blot and immunofluorescence. Additionally, miRNA sequencing was performed on induced ADSCs, followed by bioinformatic analysis and validation of the results. Results: SC-Exos were taken up by human ADSCs. The RNA and protein expression levels of S100, NGFR, MPZ and GFAP were found to be significantly higher in the SC-Exo induction group than in the uninduced group, despite no significant difference to the Dezawa’s method group, which was also consistent with the immunofluorescence results. According to the sequencing results, there were a total of 72 differentially expressed miRNAs. Bioinformatics analysis indicated that 3506 Gene Ontology terms and 98 Kyoto Encyclopedia of Genes and Genomes pathways were significantly enriched. Ten miRNAs, 6 target mRNAs and elevated expression of the PIK3CD/Akt pathway were validated by RT-qPCR or Western blot, which is consistent with the sequencing results. Conclusions: Our data suggest that SC-Exos are able to induce the differentiation of ADSCs into SCs in vitro. It is speculated that the differentially expressed miRNAs play a significant role in the differentiation process.

Project description:Mesenchymal stem cells (MSCs)-derived exosomes (exo) have shown comprehensive application prospects over the years. Despite similar functions, exomes from different origins present heterogeneous characteristics and components; however, there are no relevant proteomic analyses. In this study, we isolated exosomes from MSCs, derived from different tissues, by ultracentrifugation. A total of 1014 proteins were detected using a label-free method and analyzed with bioinformatics tools. The results revealed their shared function in the extracellular matrix receptor. Bone marrow-MSCs-derived exosomes showed superior regeneration ability. Likewise, adipose tissue-MSCs-derived exosomes played a significant role in immune regulation. Whereas, umbilical cord-MSCs-derived exosomes were more prominent in tissue damage repair.

Project description:Adipose tissue harbours a significant number of multipotent adult stem cells of mesenchymal origin known as adipose-derived stem cells (ADSCs). Broad differentiation potential and convenient accessibility of ADSCs make them an attractive source of adult mesenchymal stem cell for regenerative medicine and cell developmental plasticity research. Genome-wide microarray expression profiling was performed to identify genes deregulated during osteogenic differentiation of ADSCs to evaluate developmental plasticity of these cells. Dynamics of epigenetic modifications were analyzed in parallel and associated with the gene expression profile. Gene expression profile was analyzed in adipose-derived stem cells (ADSCs) differentiated into osteogenic lineage from 3 donors and compared to undifferentiated cells from the same donors.
