Project description: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.

Project description:Etv2 transgene was expressed from ROSA26 locus by removing floxed STOP cassette by Tie-2 Cre transgene. VE-Cad+/CD45= or VE-Cad+/CD45+ cells were sorted from control or tie-2-Etv2 E11.5 embryos (YS;yolk sac and Emb;embryo proper)and compared for gene expression in duplicate.
Project description:We discover that ER71/ETV2 initiates hemangiogenic program by activating blood and endothelial cell lineage specifying genes while enhancing FLK1 expression and expanding hemangioblast population. Furthermore, ER71/ETV2 establishes an ETS hierarchy by directly activating Ets genes in hematopoietic and endothelial cell lineage development. As such, ER71/ETV2-initiated blood and endothelial cell program is maintained by ER71/ETV2 downstream ETS factors through an ETS switching mechanism. ChIP-seq analysis of ER71 in differentiated embryonic stem 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.
