Label-free quantitative analysis proteomic profiles of human embryonic stem cell derived exosomes

ABSTRACT: In order to investigate the characteristics and mechanisms of embryonic stem cell derived exosomes attenuates transverse aortic constriction induced ventricular remodeling, the proteomic profiles of human embryonic stem cell derived exosomes were analysed by label-free quantification.

Embryonic stem sell differentiation time course

Project description:During in vitro differentiation, pluripotent stem cells undergo extensive remodeling of their gene expression profiles. While studied extensively at the transcriptome level, much less is known about protein dynamics, which might differ significantly from their mRNA counterparts. Here, we present deep proteome-wide measurements of protein levels during the differentiation of embryonic stem cells.

Highly efficient derivation of ventricular cardiomyocytes from induced pluripotent stem cells with a distinct epigenetic signature

Project description:The generation of sufficient numbers of mature ventricular myocytes for effective cell-based therapy is a central barrier for cardiac regenerative medicine. Here we demonstrate that induced pluripotent stem cells (iPSCs) can be derived from murine ventricular myocytes, and consistent with other reports of iPSCs derived from various somatic cell types, ventricular myocyte derived iPSCs (ViPSCs) exhibit a markedly higher propensity to differentiate into beating cardiomyocytes as compared to genetically-matched embryonic stem cells (ESCs) or iPSCs derived from tail-tip fibroblasts. Strikingly, ViPSC-derived cardiomyocytes form up to 99% ventricular myocytes suggesting that ventricular myocyte-derived iPSCs may be a viable strategy to generate specific cardiomyocyte subtypes for cell-based therapies. The enhanced ventricular myogenesis in ViPSCs is mediated via increased numbers of cardiovascular progenitors at early stages of differentiation. In order to investigate the mechanism of enhanced ventricular myogenesis from ViPSCs, we performed global gene expression and DNA methylation analysis, which revealed a distinct epigenetic signature that may be involved in specifying the ventricular myocyte fate in pluripotent stem cells. Total RNA was extracted from mouse ES cells, tail tip fibroblasts (TTFs), ventricular myocytes (VMs), TTF-derived induced pluripotent stem cells (TiPSCs) and VM-derived induced pluripotent stem cells (ViPSCs). Global gene expression profiling was performed using affymetrix mouse 430 2.0 gene arrays.

Myocardial proteome changes in aortic stenosis rats subjected to long-term aerobic exercise

Project description:The effects of exercise training (ET) on the heart of aortic stenosis (AS) rats are controversial and the mechanisms involved in alterations induced by ET have been poorly clarified. In this study we analyzed the myocardial proteome to identify proteins modulated by moderate intensity aerobic ET in rats with chronic supravalvar AS. Wistar rats were divided into four groups: sedentary control (C-Sed), exercised control (C-Ex), sedentary aortic stenosis (AS-Sed), and exercised AS (AS-Ex). ET consisted of five treadmill running sessions per week for 16 weeks. Statistical analysis was performed by ANOVA or Kruskal-Wallis and Goodman tests. Results were discussed at a significance level of 5%. At the end of the experiment, AS-Ex rats had higher functional capacity, lower blood lactate concentration, and better cardiac structural and left ventricular functional parameters than the AS-Sed. Myocardial proteome analysis showed that AS-Sed had higher protein expressions related to the glycolytic pathway, oxidative stress, and inflammation, and lower protein expressions related to beta-oxidation than C-Sed. AS-Ex had higher expression of one protein related to mitochondrial biogenesis and lower protein expressions associated with oxidative stress and inflammation than AS-Sed. Proteomic data were validated for proteins related to lipid and glycolytic metabolism. In conclusion, chronic pressure overload changes the expression of myocardial proteins that are mainly involved in lipid and glycolytic energy metabolism in rats. Moderate intensity aerobic training attenuates protein expressions related to oxidative stress and inflammation and increases protein expressions related to mitochondrial biogenesis. Protein changes are associated with improved functional capacity, cardiac remodeling and left ventricular function in aortic stenosis rats.

Genetic profiling and surface proteome analysis of epicardial derived cells reveals cardiogenic potential

Project description:Rationale: Epicardium-derived cells (EPDC) are formed in response to myocardial infarction and recapitulate an embryonic program that is likely to participate in cardiac regeneration and remodeling. The existence of atrial counterparts that are potentially involved in atrial remodeling is still elusive. Objective: We have elaborated and validated techniques for the robust isolation and cultivation of atrial and ventricular EPDC from the rat heart and compared their molecular phenotype with human atrial stromal cells obtained from tissue biopsies. Methods and Results: In vitro culture revealed that rat and human cells display a similar morphology, are highly enriched for the epicardial markers WT-1 and Tbx18 throughout in vitro expansion, strongly express the stem/progenitor cell markers CD73, CD90 and, surprisingly the early and late cardiac markers Gata4, Tbx5 and troponin T. In general, these cells display a similar molecular signature - which is different from human MSC - when analyzed by FACS, immunohistochemistry and real time PCR. We also examined the cell surface proteome of human and rat EPDC using cell surface biotinylation combined with nano-liquid chromatography - mass spectrometry. Proteome analysis revealed the presence of 149 overlapping proteins and >200 species specific proteins. These proteins are preferentially involved in cardiac repair and regeneration. Conclusions: This study demonstrates that atrial stromal cells are EPDC suggesting a common epicardial precursor. Cell surface proteome analysis suggests that atrial and ventricular EPDC are likely to play an important role during atrial and ventricular remodeling.
