(Submitter supplied) Endothelial differentiation occurs during normal vascular development in the developing embryo. Mouse embryonic stem (ES) cells were used to further define the molecular mechanisms of endothelial differentiation. By flow cytometry a population of VEGF-R2 positive cells was identified as early as 2.5 days after differentiation of ES cells, and a subset of VEGF-R2 + cells, that were CD41+ positive at 3.5 days. more...

(Submitter supplied) Screening for genes up in Etv2+ cells within Flk-1+ ES derived mesoderm Microarray analysis performed to screen for the candidate genes regulated by Etv2. Differentiated Flk-1+ mesoderm can be devided into Etv2+ or-. Etv2+ cells are assumed to be committed to hemato/endothelial cells. Comparison of two populations can reveal genes relevant in this commitment.

(Submitter supplied) 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. more...

(Submitter supplied) RNA microarrays technology was used to compare hESC-derived cell populations to undifferentiated hESC and to human EL cell populations. Microarrays confirmed the hematoendothelial, endothelial and hematopoietic identity of hPSC-derived CD144+-EBs, BCs and ECs, respectively, and the similarities between hESC-derived cell populations and human EL equivalent populations.

(Submitter supplied) Embryonic stem (ES) cells, when grown in suspension culture without feeders, spontaneously form round structures known as embryoid bodies. Given the appropriate conditions, these cells can differentiate over time into precursors of all three germ layers. Embryoid bodies, in a disorganized way, mimic early embryonic development to a certain extent and can be used as a synchronously differentiating large scale source of tissue for the study of biological determinants of early differentiation. more...

(Submitter supplied) 3 different ES cell lines were compared in order to determine whether there are significant expression profile differences between ES cell lines, or whether the constraints of maintaining pluripotency in culture force a similar expression profile on cell lines derived from disparate sources. Our results indicate that the latter is more likely. We identified 21 genes that were significantly differentially regulated, either on comparison with the pooled control, or on direct comparison of individual ES cell line data from different slides. more...

(Submitter supplied) To assess changes in the miRNA-ome during the early stages of endothelial differentiation, the expression of mature human miRNAs at days 2, 4 and 10 of endothelial differentiation (vs pluripotent time-matched samples) in SA461 hESC cell line was analysed in a two-channel microarray. Expression of the pluripotency-associated miRNAs miR-302a – d and miR-372 and miR-373 was significantly suppressed with progression of differentiation. more...

(Submitter supplied) GBM is a heterogenous brain tumor with hyperproliferation of endothelial cells. In order to understand the cellular mechanism of vasculogenesis in GBM, four fractions of cells are seperated. Microarray assays was performed to examine the potential lineage relationship and the signal pathways involved in determining the cell identity and function.

(Submitter supplied) Differentiation of human embryonic stem cells into endothelial cells (hESC-ECs) has the potential to provide an unlimited source of cells for novel transplantation therapies of ischemic diseases by supporting angiogenesis and vasculogenesis. In this study, we developed an extracellular matrix culture system for increasing endothelial differentiation and free from contaminating animal cells. We investigated the transcriptional changes that occur during endothelial differentiation of hESCs using whole genome microarray, and compared to human umbilical vein endothelial cells (HUVECs). more...

(Submitter supplied) 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.

(Submitter supplied) Human ES or iPS Cells were differentiated into endothelial cells (ECs) defined by expression of CD31 (PECAM1) and CD144 (VE-Cadherin) on the cell surface. All ES or iPS derived ECs were greater than 90% double positive for these two markers. These in vitro derived ECs were compared to each other and to ECs from primary cell sources; arterial (aortic Ecs), venous (saphenous vein) and lymphatic.

(Submitter supplied) The pathways involved in hierarchical differentiation of human embryonic stem cells (hESC) into abundant and durable endothelial cells (EC) are unknown. We employed an EC-specific VE-cadherin promoter driving GFP (hVPr-GFP) to screen for factors that augmented yields of vascular-committed ECs from hESCs. In phase 1 of our approach, inhibition of TGFb, precisely at day 7 of hESC differentiation, enhanced emergence of hVPr-GFP+ ECs by 10-fold. more...

(Submitter supplied) Biologists rely on morphology, function, and specific markers to define the differentiation status of cells. Transcript profiling has expanded the repertoire of these markers by providing the snapshot of cellular status that reflects the activity of all genes. However, such data have been used only to assess relative similarities and differences of these cells. Here we show that principal component analysis (PCA) of global gene expression profiles map cells in multidimensional transcript profile space and the positions of differentiating cells progress in a stepwise manner along trajectories starting from undifferentiated embryonic stem (ES) cells located in the apex. more...
