Project description:ES cells differentiated in the presence of the Wnt inhibitor DKK1 fail to express the transcription factor Snail and undergo EMT or mesoderm differentiation. We generated an ES cell line, A2.snail, that induced Snail expression upon addition of doxycycline addition. Microarrays were used to gain a global picture of Flk1- and Flk1+ cells generated one day after Snail was expressed during Wnt inhibition.

We generated an ES cell line, A2.snail, that induced Snail expression upon addition of doxycycline addition. Microarrays were used to gain a global picture of Flk1- and Flk1+ cells generated one day after Snail was expressed during Wnt inhibition. A2.snail ES cells, which express Snail upon addition of doxycycline, were differentiated as embryoid bodies in differentiation media and DKK1. Snail-induced cultures uniquely develop a select population of Flk1+ cells. Total RNA was harvested from sorted control (no doxycycline) Flk1- cells and sorted Snail-induced (doxycycline at day 2) Flk1- and Flk1+ cells at day 3 of differentiation.

We generated an ES cell line, A2.snail, that induced Snail expression upon addition of doxycycline addition.

Total RNA was harvested from control (no doxycycline) and Snail-induced (doxycycline at day 2) cultures at 6, 12, and 24 hours after doxycycline addition (corresponding to days 2.25, 2.5, and 3 of differentiation).

Project description:Embryonic stem (ES) cells have the potential to generate a variety of cell lineages including endothelial cells, blood cells and smooth muscle cells. flk1-expressing cells derived from ES cells serve as vascular progenitors. We have used global gene expression analysis in order to establish a comprehensive list of candidate genes in the developing vasculature during ES cell differentiation in vitro. A large set of genes, including growth factors, cell surface molecules, transcriptional factors, and members of several signal transduction pathways that are known to be involved in vasculogenesis or angiogenesis, were found to have expression patterns as expected. Some unknown or functionally uncharacterized genes were differentially regulated in flk1+ cells compared with flk1 cells, suggesting possible roles for these genes in vascular commitment. Particularly, multiple components of the Wnt signaling pathway were differentially regulated in flk1+ cells, including Wnt proteins, their receptors, downstream transcriptional factors, and other components belonging to this pathway. Activation of the Wnt signal was able to expand vascular progenitor populations whereas suppression of Wnt activity reduced flk1+ populations. Suppression of Wnt signaling also inhibited the formation of matured vascular capillary-like structures during late stages of EB differentiation. These data indicate a requisite and ongoing role for Wnt activity during vascular development, and the gene expression profiles identify candidate components of this pathway that participate in vascular cell differentiation.

Project description:Blood and endothelial cells arise from hemangiogenic progenitors that are specified from FLK1-expressing mesoderm by the transcription factor ETV2. FLK1 mesoderm also contributes to other tissues, including vascular smooth muscle (VSM) and cardiomyocytes. However, the developmental process of FLK1 mesoderm generation and its derivatives and the lineage relationship among FLK1 mesoderm derivatives these tissues remain obscure. Recent single cell RNA-sequencing (scRNA-seq) studies of early stages of embryogenesis embryos, or in vitro differentiated human embryonic stem (ES) cells have differentiation provided unprecedented information on the spatiotemporal resolution of cells in embryogenesis. Nonetheless, these snapshots still nonetheless offer insufficient information on dynamic developmental processes due to inadvertently missing intermediate states and unavoidable batch effects. Here we performed scRNA-seq of mouse ES cells in asynchronous embryoid bodies (EBs), in vitro differentiated embryonic stem (ES) cells containing undifferentiated ES cells and its differentiated hemangiogenic progeny, as well as yolk sacs, the first hematopoietic extraembryonic tissue in developing embryo that contains hemangiogenic and VSM lineages. We captured a continuous developmental process from undifferentiated pluripotent cells to FLK1 mesoderm-derived tissues involved in hemangiogenesis. This continuous transcriptome map will benefit both basic and applied studies of mesoderm and its derivatives.

Project description:Our study shows that TGF-β signaling promotes tumorigenesis in the liver through upregulation of its target gene, Snail. We explored gene expression changes in tumors following TGF-β inhibition, and tumors ectopically expressing Snail with the TGF-β inhibition. RNA samples were harvested from tumors expressing Smad7 (S7HP tumors), firefly luciferase (LHP tumors), and Smad7 plus Snail (S7HP+Snail), respectively. Differentially expressed genes were investigated in LHP and S7HP+Snail tumors, compared with S7HP tumors.

Project description:We found that mouse ES cell-derived Flk1+ cells could be subdivided into three population by the expression of PDGFRa and CAR (Flk1+PDGFRa-CAR-, Flk1+PDGFRa-CAR+, and Flk1+PDGFRa+CAR+). Therefore, global gene expression analysis was perfomed by microarray to characterize these mesodermal subsets.
