Megjegyzések:Brown adipocytes, abundant in deep-neck (DN) area in humans, are thermogenic with anti-obesity potential. FTO pro-obesity rs1421085 T-to-C SNP shifts differentiation program towards white adipocytes in subcutaneous fat. Human adipose-derived stromal cells were obtained from subcutaneous neck (SC) and DN fat of 9 donors, of which 3-3 carried risk-free (T/T), heterozygous or obesity-risk (C/C) FTO genotypes. They were differentiated to white and brown (long-term PPAR? stimulation) adipocytes, then global RNA sequencing was performed and differentially expressed genes (DEGs) were compared. DN and SC progenitors had similar adipocyte differentiation potential but differed in DEGs. DN adipocytes displayed higher browning features according to ProFAT or BATLAS scores and characteristic DEG patterns revealing associated pathways which were highly expressed (thermogenesis, interferon, cytokine, retinoic acid, with UCP1 and BMP4 as prominent network stabilizers) or downregulated (particularly extracellular matrix remodelling) compared to SC ones. Part of DEGs in either DN or SC browning was PPAR?-dependent. Presence of the FTO obesity-risk allele suppressed the expression of mitochondrial and thermogenesis genes with a striking resemblance between affected pathways and those appearing in ProFAT and BATLAS, underlining the importance of metabolic and mitochondrial pathways in thermogenesis. Among overlapping regulatory influences which determine browning and thermogenic potential of neck adipocytes, FTO genetic background has a so far not recognized prominence.

Cím:Effect of Inflammatory Microenvironment on the Regenerative Capacity of Adipose-Derived Mesenchymal Stem Cells / Szűcs Diána, Miklós Vanda, Monostori Tamás, Guba Melinda, Kun-Varga Anikó, Póliska Szilárd, Kis Erika, Bende Balázs, Kemény Lajos, Veréb Zoltán

Megjegyzések:Adipose-derived mesenchymal stem cells are increasingly being used in regenerative medicine as cell therapy targets, including in the treatment of burns and ulcers. The regenerative potential of AD-MSCs and some of their immunological properties are known from in vitro studies; however, in clinical applications, cells are used in non-ideal conditions and can behave differently in inflammatory environments, affecting the efficacy and outcome of therapy. Our aim was to investigate and map the pathways that the inflammatory microenvironment can induce in these cells. High-throughput gene expression assays were performed on AD-MSCs activated with LPS and TNF?. Analysis of RNA-Seq data showed that control, LPS-treated and TNF?-treated samples exhibited distinct gene expression patterns. LPS treatment increased the expression of 926 genes and decreased the expression of 770 genes involved in cell division, DNA repair, the cell cycle, and several metabolic processes. TNF? treatment increased the expression of 174 genes and decreased the expression of 383 genes, which are related to cell division, the immune response, cell proliferation, and differentiation. We also map the biological pathways by further investigating the most altered genes using the Gene Ontology and KEGG databases. Secreted cytokines, which are important in the immunological response, were also examined at the protein level, and a functional assay was performed to assess wound healing. Activated AD-MSC increased the secretion of IL-6, IL-8 and CXCL-10, and also the closure of wounds. AD-MSCs presented accelerated wound healing under inflammation conditions, suggesting that we could use this cell in clinical application.

Cím:Vessel Wall-Derived Mesenchymal Stromal Cells Share Similar Differentiation Potential and Immunomodulatory Properties with Bone Marrow-Derived Stromal Cells / Veréb Zoltán, Mázló Anett, Szabó Attila, Póliska Szilárd, Kiss Attila, Litauszky Krisztina, Koncz Gábor, Boda Zoltán, Rajnavölgyi Éva, Bácsi Attila

Megjegyzések:This study is aimed at investigating the phenotype, differentiation potential, immunomodulatory properties, and responsivenessof saphenous vein vessel wall-derived mesenchymal stromal cells (SV-MSCs) to various TLR ligands and proinflammatory cytokines, aswell as comparing their features to those of theirbone marrow-derived counterparts (BM-MSCs).Methods. SV-MSCs were isolated byenzymatic digestion of the saphenous vein vessel wall. Phenotype analysis was carried out byflow cytometry and microscopy, whereasadipogenic, chondrogenic, and osteogenic differentiation potentials were tested inin vitroassays. For comparative analysis, theexpression of different stemness, proliferation, and differentiation-related genes was determined by Affymetrix gene array. To comparethe immunomodulatory properties of SV-MSCs and BM-MSCs, mixed lymphocyte reaction was applied. To investigate theirresponses to various activating stimuli, MSCs weretreated with TLR ligands (LPS, PolyI:C) or proinflammatory cytokines (TNF?,IL-1?,IFN?), and the expression of various early innate immune response-related genes was assessed by qPCR, while secretion ofselected cytokines and chemokines was measured by ELISA.Results. The isolated SV-MSCs were able to differentiate into bone, fat,and cartilage cells/directionin vitro. SV-MSCs expressed the most important MSC markers (CD29, CD44, CD73, CD90, and CD105)and shared almost identical phenotypic characteristics with BM-MSCs. Their gene expression pattern and activation pathways wereclose to those of BM-MSCs. SV-MSCs showed better immunosuppressive activity inhibiting phytohemagglutinin-induced Tlymphocyte proliferationin vitrothan BM-MSCs. Cellular responses to treatments mimicking inflammatory conditions werecomparable in the bone marrow- and saphenous vein-derived MSCs. Namely, similar to BM-MSCs, SV-MSCs secreted increasedamount of IL-6 and IL-8 after 12- or 24-hour treatment with LPS, PolyI:C, TNF?,orIL-1?,comparedtountreatedcontrols.Interestingly, a different CXCL-10/IP-10 secretion pattern could be observed under inflammatory conditions in the two types ofMSCs.Conclusion. Based on our results, cells isolated from saphenous vein vessel wall fulfilled the ISCT's (International Society forCellular Therapy) criteria for multipotent mesenchymal stromal cells, and no significant differences in the phenotype, gene expressionpattern, and responsiveness to inflammatory stimuli could be observed between BM-MSCs and SV-MSCs, while the latter cells havemore potent immunosuppressive activityin vitro. Further functional assays have to be performed to reveal whether SV-MSCs couldbe useful for certain regenerative therapeutic applications or tissueengineering purposes.
