Gene expression profiling in Tie-2-Etv2 YS hematopoietic precursors

ABSTRACT: Etv2 transgene was expressed from ROSA26 locus by removing floxed STOP cassette by Tie-2 Cre transgene.VE-Cad+/CD45+ cells were sorted from control or tie-2-Etv2 E10.5 embryosYS(yolk sac) and compared for gene expression in duplicate. This study will reveal the effect of Etv2 transgene in E10.5 mouse embryo yolk sac. The effect of Etv2 overexpression in relevant mouse tissue will be important to understand its effect in comparison with in ES cells. Genes aberrantly regulated by Etv2 overexpression will help to understand the caveat when using Etv2 to induce endothelial and hematopoietic cells in vitro.

Gene expression profiling in Vav-Etv2 KSL and Granulocyte hematopoietic cells

Project description:Etv2 transgene was expressed from ROSA26 locus by removing floxed STOP cassette by Vav Cre transgene. KSL or Mac1+/Gr1+ cells were sorted from control or Vav-Etv2 bone marrow and compared for gene expression in duplicate. This study will reveal the effect of Etv2 transgene in adult hematopoietic cells. The effect of Etv2 overexpression in relevant mouse tissue will be important to understand its effect in comparison with in ES cells. Genes aberrantly regulated by Etv2 overexpression will help to understand the caveat when using Etv2 to induce endothelial and hematopoietic cells in vitro.

Gene expression analysis of inducible ES cells overexpressing Etv2 (induced for 12 hours at day 3 of differentiation)

Project description:During embryogenesis, the endothelial and the hematopoietic lineages first appear during gastrulation in the blood island of the yolk sac. We have previously reported that an Ets variant gene 2 (Etv2/ER71) mutant embryo lacks hematopoietic and endothelial lineages, however, the precise roles of Etv2 in yolk sac development remains unclear. We carried out a transcriptome analysis using an ES cell line that can inducibly express Etv2. Cells were induced for 12 hours at day 3 of differentiation. An ES cell line (dervied from mouse of background strain 129P2/Ola) with a doxycycline inducible expression casette of Etv2 (ER71 A2Lox.cre) was differentiated in hanging drops. At 3 days of differentiation, cells were treated with doxycycline for 12 hours, and subsequently Flk1(+) cells were sorted. Experiment was done in triplicate and untreated cells were used for control.

Genome-wide analysis of gene expression of Flk1Cre;ETV2 CKO mouse yolk sacs.

Project description:To identify genes critical for vascular development, we generated mice where ETV2 is inactivated in FLK1+ cells by a loxP-Cre recombination approach. Results provide a detailed insight into the function of ETV2 in emrbyonic vasculare formation. Total RNA obtained from E9.5 yolk sacs from Flk1Cre;ETV2 CKO and control mice.

Comparison of gene expression pattern between Wild-type and Hypb knockout embryo yolk sacs

Project description:This study aimed at exploring the physiological function of mammalian HYPB by means of knockout mouse model. Homogenous disruption of mouse Hypb gene leads to embryonic lethality at E10.5-E11.5. Severe vascular defects were observed in the Hypb-/- embryos, yolk sac and placenta.In the mutant embryo and yolk sac, disorganized and abnormally dilated capillaries cannot be remodeled into large blood vessels or intricate networks. Thus, our results suggest that the mammalian HYPB HMT plays an important role in embryonic vascularization. Keywords: knockout, mouse embryo development, angiogenesis, yolk sac, E9.0, E10.5
