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: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.

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.

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.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.
