Project description:Nodal/Activin signaling directs mesendoderm specification in early vertebrate embryogenesis. We have characterized transcriptional profiling of human embryonic stem cells and Activin-treated cells at different timepoints. In this dataset, we include the timecourse gene expression data obtained from hESC differentiation post Activin treatment, examining at day 0, 1, 3 and 5.
Project description:Activin A is known to induce endodermal differentiation in human embryonic stem cells under low-serum or certain defined media conditions. To gain insights into global gene expression changes during Activin A-induced differentiation, gene expression was monitored by means of microarrays in short intervals until 4 days of treatment. Keywords: Differentiation timecourse experiment
Project description:Human embryonic stem cells were converted into GATA3-expressing extraembryonic cells (GATA3+ ExE cells) when they were exposed to chemical inhibitors for ACTIVIN/NODAL (A83-01, 1uM) and FGF signaling (PD03714, 100nM). We refer here to this inhibitor-induced differentiation method as an 'AP' protocol. To understand the transcriptome dynamics during AP-induced differentiation, we performed timecourse profiling of genome-wide gene expression by RNA sequencing.
Project description:Nodal/Activin signaling directs mesendoderm specification in early vertebrate embryogenesis. We have characterized transcriptional profiling of human embryonic stem cells and Activin-treated cells at different timepoints. In this dataset, we include the timecourse gene expression data obtained from hESC differentiation post Activin treatment, examining at day 0, 1, 3 and 5. Four biological replicates were used for day 0, three for day 1, three for day 3, and four for day 5. Cells were harvested and used for total RNA preparation using Trizol (Invitrogen). Gene expression was analyzed using GeneChip Human Exon 1.0 ST Array (Affymetrix).
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
