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.

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.

Project description:ETV2/ER71, an ETS transcription factor, is critical for hematopoiesis and vascular development. However, knowledge on the molecular mechanisms behind ETV2-mediated gene transcription is limited. Here, we show that ETV2 together with KDM4A, an H3K9 demethylase, regulates hematopoietic and endothelial genes. Etv2-/- mouse embryonic stem cells (mESCs), which fail to generate hematopoietic and endothelial cells, showed enhanced levels of H3K9me3 on hematopoietic and endothelial genes. ETV2 interacts with KDM4A and the ETV2-mediated transcriptional activation of hematopoietic and endothelial genes is dependent on KDM4A histone demethylase activity. ETV2 and KDM4A co-occupy the transcription regulatory regions of genes whose expression is directly regulated by ETV2. Mice lacking Kdm4a and Etv2 in endothelial cells (Cdh5Cre;Kdm4af/f;Etv2f/f) displayed a more severe defect in perfusion recovery and neovascularization compared with Cdh5Cre;Kdm4af/f, Cdh5Cre;Etv2f/f mice and controls. Collectively, we demonstrated that ETV2 interacts with KDM4A and that this interaction is critical for FLK1+ cell generation, differentiation into the downstream lineages, and vascular regeneration.

Project description:Samples 1-6: HDFs transduced with ER71/ETV2 were sorted on KDR expression at day 7. The isolated KDR+ cells together with human umbilical venous endothelial cells (HUVECs) and untransduced HDFs were subjected to genomic gene expression profiling. A significant number of genes related with vessel development and angiogenesis was significantly upregulated in KDR+ cells, compared to control HDFs. These findings strongly argue that ER71/ETV2 directly reprograms human fibroblasts to functional endothelial-like cells, which could be useful for disease investigation as well as autologous cell therapy. Samples 7-12: HDFs transduced with ER71/ETV2 were sorted on KDR expression at day 7. The isolated KDR+ cells were further cultured up to day 93. The further cultured cells together with human umbilical venous endothelial cells (HUVECs) and untransduced HDFs were subjected to genomic gene expression profiling. A significant number of genes related with vessel development and angiogenesis was significantly upregulated in the further cultured cells, compared to control HDFs. These findings strongly argue that ER71/ETV2 directly reprograms human fibroblasts to functional endothelial-like cells, which could be useful for disease investigation as well as autologous cell therapy.

Project description:Ets transcription factor ER71 is critical for Flk-1 mesoderm specification to different cell lineages. In this dataset, we determine to investigate the mechanisms by which ER71 regulates hematopoietic and endothelial cell versus cardiac cell lineage development. Expression of all four Flk-1+ mesoderm populations (i.e. Er71 overexpressed versus control, Er71 deficient versus control Flk-1+ mesoderm) was compared. Specifically, we sorted Flk-1+ mesoderm from day 3 differentiated embryonic stem(ES) cells, including induced Er71 and control ES cells, as well as Er71+/+ as well as Er71-/- ES cells .

Project description:Successful derivation of a specific cell lineage from pluripotent stem cells will tremendously facilitate the clinical usage of pluripotent stem derived somatic cells. Herein, we demonstrate that ER71/Etv2, GATA2 and Scl form a core network in hemangioblast development and that transient co-expression of these three factors robustly induced hemangioblasts from ES cells. Such induced hemangioblasts potently generated hematopoietic and endothelial cells in culture as well as in vivo, warranting the evaluation of these cells in the future for repairing and/or regenerating hematopoietic and/or angiogenic defects. We have established a doxycycline inducible ES cell, iEGS, in which ER71/Etv2, GATA2 three transcription factors can be transiently co-expressed by doxycycline induction. We further analyzed the downstream target genes and signaling pathways at 6, 12 and 24hrs after ER71/Etv2, GATA2 induction. These data were obtained from three independent experiments.
