Project description:miRNA profiling of undifferentiated and neuro-differentiated adipose-derived stem cells. Adipose-derived stem cells obtained from 4 different donors were divided into 2 groups, undifferentiated "control" group and neurally-differentiated "neuro" group. miRNA of each cells were analyzed using Agilent miRNA microarray.

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: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.

Project description:we analyzed the expression level change of transcription factors in adipose derived stem cells during osteogenic differentiation and found a candidate target gene, Sox11. We defined that Sox11 suppresses osteogenic differentiation through overexpression and knock down of Sox11. total RNA obtained from adipose derived stem cells subjected to 1,3,6,10 or 14 days in osteogenic differentiation compared to undifferentiated control adipose derived stem cells.

Project description:Treatment strategies of critical nerve injuries involving nerve gaps more than 3 cm are still not optimal. The need for an alternative to the standard autologous nerve grafts has led to the exploration of adipose derived stem cells (ASC) seeded in bioartificial nerve conduits for enhancement of peripheral nerve regeneration. ASC can be differentiated into Schwann cell like cells, which is believed to improve their neurotrophic potency. Nevertheless, the differentiation process requires several weeks and there is no evidence that the cells maintain their differentiated phenotype in vivo. Thus, the present study evaluated the synergistic effect of undifferentiated ASC with exogenously added growth factors in vitro with the aim to improve the neurotrophic potency of undifferentiated ASC through short ex-vivo stimulation with growth factors. The study furthermore provides a comparative in vitro assay of the six well-known neurotrophic factors NGF, GDNF, BDNF, CNTF, NT3 and NT4. ASC were cultured and thus stimulated in the presence of the respective exogenous growth factor for three days and resulting conditioned medium was evaluated in an in vitro axonal outgrowth assay. In addition, also unstimulated ASC’s conditioned medium was tested in combination with the respective exogenous growth factor for the same assay, which was perfomed on dorsal root ganglion (DRG) explants from 10 days old embryonic chicken. DRG explants from most promising conditions were further analyzed for upregulated STAT-3 and GAP-43 by qRT-PCR. Furthermore, also proteomics and phosphoproteomics were performed for ASC and DRG explants using mass spectrometry. The quantity of selected proteins contained in the ASC’s conditioned medium was investigated by ELISA. Combination of ASC’s conditioned medium with growth factors generally resulted in significantly enhanced axonal outgrowth when compared with their control of DRG explants cultured with the respective growth factor only. Specifically, conditioned medium derived from NT3-stimulated as well as ASC’s conditioned medium supplemented with NT3 or BDNF elicited significant axonal outgrowth from DRG explants in contrast to all other experimental conditions. Significant upregulation of STAT-3 and GAP-43 was evidenced for DRG explants grown in NT3-stimulated ASC’s conditioned medium and to a certain extent also for DRG cultured in ASC’s conditioned medium supplemented with NT3.

Project description:We reported the application of next generation sequencing technology for high-throughput profiling of miRNA expression in human primary lung fibroblast Cells with undifferentiated (fibroblast) or differentiated (myofibroblast) status. By comparation the expression aboundence of known miRNAs between undifferentiated and differentiated type human primary lung fibroblast cells, we found both upregulated and downregulated miRNAs in fibroblast cells during differentiation. This study provides a basic condition for further investigation of the roles of the regulated miRNAs during differentiation in fibroblast cells.
