Description
The discovery of the first histone demethylase in 2004 (LSD1/KDM1) opened new avenues for the understanding of how histone methylation impacts cellular functions. A great number of histone demethylases have been identified since, which are potentially linked to gene regulation as well as to stem cell self-renewal and differentiation. KDM6A/UTY and KDM6B/JMJD3 are both H3K27me3/2-specific histone demethylases, which are known to play a central role in regulation of posterior development, by regulating HOX gene expression. So far nothing is known about the role of histone lysine demethylases (KDMs) during early hematopoiesis. We are studying the role of KDM6A and KDM6B on self-renewal, global gene expression and on local and global chromatin states in embryonic stem cells (ESCs) and during differentiation. In order to completely abrogate KDM6 demethylase activity in ESCs we employed a specific inhibitor (GSK-J4, Kruidenier et al. 2012). Treatment of ESCs with GSK-J4 had no effect on viability and proliferation . However, ESC differentiation in the presence of GSK-J4 was completely abrogated. In conclusion we show that ESC differentiation is completely blockend in the absence of any H3K27 demethylase activity.

Description
Study of Sox18 regulated genes: Human umbilical vein endothelial cells (HUVEC) were either transduced with adenoviral vectors expressing SOX18 from an IRES-EGFP casette, or IRES-EGFP alone, or left untreated. After 16 hours, mRNA was isolated and analyzed by hybridization to Affymetrix HG-U133A arrays.

Description
The epicardium, an epithelium covering the heart, is essential for cardiac development. During embryogenesis, the epicardium provides instructive signals for the growth and maturation of cardiomyocytes and for coronary angiogenesis. We generated an in vitro model of human embryonic epicardium derived from human pluripotent stem cells (hPSC-epi). These cells were able to differentiate into cardiac fibroblasts (cf) and smooth muscle cells (smc) in vitro (hPSC-epi-cf and hPSC-epi-smc respectively). Furthermore, we showed that they improved maturation of hPSC-derived cardiomyocytes (hPSC-cardio) in vitro while neural crest cells derived from hPSC (hPSC-NC) could not. Furthermore, they improved survival of hPSC-cardio and stimulated angiogenesis when injected in a rat model of myocardium infarction. We performed mRNA sequencing of the hPSC-epi, hPSC-epi-cf, hPSC-smc and hPSC-NC in order to identify the secreted molecules specifically produced by the hPSC-epi and/or its derivatives in comparison with the hPSC-NC. Vascular smooth muscle cells have different embryonic origins and different properties depending on their location in the body. The coronary smooth muscle cells come from the epicardium while the aortic ones come from the mesoderm or the neural crest. We performed mRNA sequencing of human coronary artery smc and human aortic smc to identify a specific signature of the coronary smc. We also compared the genes expressed in the hPSC-epi-smc and the smc derived from hPSC-derived lateral plate mesoderm. Overall design: For hPSC-derived samples the three replicates are coming from three different in vitro differentiations from H9. For the human primary cells, the triplicates are technical replicates (three different wells from the same culture at the same passage)

Description
Cellular differentiation is associated with changes in transcript populations. Accurate quantification of transcriptomes during development can thus provide global insights into differentiation processes including the fundamental specification and differentiation events operating during plant embryogenesis. However, multiple technical challenges have limited the ability to obtain high quality early embryonic transcriptomes, namely the low amount of RNA obtainable and contamination from surrounding endosperm and seed-coat tissues. We compared the performance of three low-input mRNA sequencing (mRNA-seq) library preparation kits on 0.1 to 5 nanograms (ng) of total RNA isolated from Arabidopsis thaliana (Arabidopsis) embryos and identified a low-cost method with superior performance. This mRNA-seq method was then used to profile the transcriptomes of Arabidopsis embryos across eight developmental stages. By comprehensively comparing embryonic and post-embryonic transcriptomes, we found that embryonic transcriptomes do not resemble any other plant tissue we analyzed. Moreover, transcriptome clustering analyses revealed the presence of four distinct phases of embryogenesis which are enriched in specific biological processes. We also compared zygotic embryo transcriptomes with publicly available somatic embryo transcriptomes. Strikingly, we found little resemblance between zygotic embryos and somatic embryos derived from late-staged zygotic embryos suggesting that somatic and zygotic embryo transcriptomes are distinct from each other. In addition to the biological insights gained from our systematic characterization of the Arabidopsis embryonic transcriptome, we provide a data-rich resource for the community to explore. Overall design: mRNA-seq libraries were generated from three biological replicates of 50 Col-0 (wild type) embryos at eight different developmental stages (i.e. 8-cell/16-cell to mature green). Additionally, mRNA-seq libraries were prepared from total RNA isolated from 50 bent-cotyledon staged embryos and then diluted to 5, 1, 0.5 or 0.1 nanograms prior to library construction with three different library preparation methods.
