Project description:Gene expression profiling reveals multiple biological functions of oleacein in diabetic model. We evaluated the effects of oleacein on diabetic human adipose-derived stem cells. We performed an untargeted whole-genome transcriptome analysis to explore functionality of oleacein in a diabetic adipose stem cell-based tool.

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:Pericytes (PCs) are multipotent contractile cells that wrap around the endothelial cells to maintain the blood vessel's functionality and integrity. The hyperglycemia associated with Type 2 diabetes mellitus (T2DM) was shown to impair the function of PCs and increase the risk of diabetes complications. In this study, we aimed to investigate the deleterious effect of the diabetic microenvironment on the regenerative capacities of human PCs. PCs isolated from human adipose tissue were cultured in the presence or absence of serum collected from diabetic patients (DS). The functionality of PCs was analysed after 6, 14, and 30 days. Microscopic examination of PCs cultured in DS (DS-PCs) showed increased aggregate formation and altered surface topography with hyperbolic invaginations. Compared to PCs cultured in normal serum (NS-PCs), DS-PCs showed more fragmented mitochondria and thicker nuclear membrane. DS caused impaired angiogenic differentiation of PCs as confirmed by tube formation, decreased VEGF-A and IGF-1 gene expression, upregulated TSP1, PF4, actin related protein 2/3 complex and downregulated COL21A1 protein expression. These cells suffered higher apoptotis and showed higher expression of Clic4, apoptosis facilitator BCl-2-like protein serine/threonine protein phosphatase, and Caspase-7 proteins. DS-PCs showed dysregulated DNA repair genes CDKN1A, SIRT1, XRCC5 and TERF2 and up-regulation of the pro-inflammatory genes ICAM1, IL-6, and TNF-α. DS treated cells also showed disruption in the expression of the focal adhesion and binding proeins TSP1, TGF- β, fibronectin and PCDH7. DS-PCs showed resistance mechanisms upon exposure to diabetic microenvironment by maitining the intracellular ROS level and upregulation of ECM organizing proteins vinculin, IQGAP1, and tubulin beta chain.These data show that the diabetic microenvironment exert a deleterious effect on the regenerative capacities of human adipose tissue-derived PCs, and may thus have possible implications on the vascular complications of type-2 diabetes mellitus. Nevertheless, their protective mechanisms when initially exposed to DS could provide a promising cellular therapy for T2DM.

Project description:Owing to the risk of insertional mutagenesis, viral transduction has been increasingly replaced by nonviral methods to generate induced pluripotent stem (iPS) cells. We report the use of âminicircleâ DNA, a vector type that is free of bacterial DNA and capable of high expression in cells. Here we use a single minicircle vector to generate transgene-free iPSCs from adult human adipose stem cells. (Note: Our Nature Methods publication included analysis of array data from GSM378832 (Foreskin), GSM378833-GSM378838 (JT-iPSC), and GSM378817-GSM378820 (H1, H7, H9, H13, H14) in conjunction with this series). Total RNA from human adipose stem cells (hASC, n = 3 replicate samples), hASC-derived iPS cells using lentiviral factors (lenti-iPSC, n = 3 replicate samples), and minicircle-derived human iPS cells (mc-iPSC, n = 3 subclones from adipose tissue of three individual patients) was hybridized to nine Affymetrix GeneChip Human Genome U133 Plus 2.0 Arrays.

Project description:In this study we aimed to gain further insight on the role of GCs in adipocyte differentiation. For the future drugability of candidate targets it is of utmost importance to find factors relevant to human biology. Thus, we analyzed the transcriptome of GC induced primary human adipose stem cells (hASC) to identify novel factors downstream of GC action We used microarrays to detail the global programme of gene expression following glucocorticoid treatment and identified distinct classes of up- and downregulated genes during this process. Human preadipocytes (human adipose stem cells) were obtained from lipoaspirates by enzamytic digestions, followed by several steps of centrifugations (Mikkelsen et. al Cell. 2010 Oct 1;143(1):156-69.). Following isolation, human adipos estemm cells were treated with Dexamethasone (100nM) for various times.

Project description:Application of autologous adipose-derived stem cells (ASC) for diabetic chronic wounds has become an emerging treatment option. However, ASCs from diabetic individuals showed impaired cell function and suboptimal wound healing effects. We proposed that adopting a low glucose level in the culture medium for diabetic ASCs may restore their pro-healing capabilities. ASCs from diabetic humans and mice were retrieved and cultured in high-glucose (HG, 4.5 g/L) or low-glucose (LG, 1.0 g/L) conditions. Cell characteristics and functions were investigated in vitro. Moreover, we applied diabetic murine ASCs cultured in HG or LG condition to a wound healing model in diabetic mice to compare their healing capabilities in vivo. Human ASCs exhibited decreased cell proliferation and migration with enhanced senescence when cultured in HG condition in vitro. Similar findings were noted in ASCs derived from diabetic mice. The inferior cellular functions could be partially recovered when they were cultured in LG condition. In the animal study, wounds healed faster when treated with HG or LG-cultured diabetic ASCs relative to the control group. Moreover, higher collagen density, more angiogenesis and cellular retention of applied ASCs were found in wound tissues treated with diabetic ASCs cultured in LG condition. In line with the literature, our study showed that a diabetic milieu exerts an adverse effect on ASCs. Adopting LG culture condition is a simple and effective approach to enhance the wound healing capabilities of diabetic ASCs, which is valuable for the clinical application of autologous ASCs from diabetic patients.

Project description:RNAseq was performed in siJARID2 and control siRNA-treated human adipose tissue derived stem cells (hASC). The tretment of siRNA was performed by electroporation one day before induction of differentiation in vitro. The cells were lyzed and RNA was purified on day 6 (mid differentiation) and day 13 (full differentiation) from differentiation start.
