Investigation of Isogenic Human Embryonic Stem Cells and Derived Induced Pluripotent Stem Cells and Differentiated Line

ABSTRACT: Briefly, the well characterized female hES cell line H9 was allowed to differentiate into a clonally purified mortal splanchnopleuric mesodermal somatic cell line EN13. The EN13 line was subsequently virally reprogrammed back to an induced pluripotent state (we term re-H9) using OCT4, SOX2, KLF4 retroviral vectors creating isogenic lines of hESC, hiPSC and mortal cells. Our results reveal several important differences between embryo-derived H9 and the induced re-H9 stem cells. We find a dysregulation of genes involved in imprinting and altered expression of X-chromosome localized genes in re-H9 cells.

Transcription profiling of human embryonic stem cells (hES) during the differentiation.

Project description:The transcriptome analysis was performed in triplicate using two human embryonic stem cells lines (hES_VUB01 and hES_SA01) by comparing the expression profiles of the undifferentiated hES cells and two types of progenitors derived from the hES cell lines: Neural progenitors (NPC) and Mesodermal progenitors (MSC). Keywords: Cell type comparison hES (6 samples originated from the two cell line, in triplicate for each : hES_VUB01_1, hES_VUB01_2, hES_VUB01_3, hES_SA01_1, hES_SA01_2, hES_SA01_3) ; NPC (6 samples originated from the two cell line, in triplicate for each : NPC_VUB01_1, NPC_VUB01_2, NPC_VUB01_3, NPC_SA01_1, NPC_SA01_2, NPC_SA01_3) ; MSC (6 samples originated from the two cell line, in triplicate for each : MSC_VUB01_1, MSC_VUB01_2, MSC_VUB01_3, MSC_SA01_1, MSC_SA01_2, MSC_SA01_3)

microRNA expression profiling among human embryonic stem cells, differerentiated EBs and adult cells

Project description:Human embryonic stem (hES) cells have unique features: self-renewal ability and pluripotency. They can be continuously cultured in undifferentiated state and give rise to cells and tissues of all three germ layers. Thus hES cells provide a resource not only for cell replacement therapy but also for studying human developmental biology. We aimed to identify the unique signature of miRNAs in human embryonic stem cells. Keywords: cell type comparison design We performed microRNA expression profiling on 3 passages from 2 different hES cell lines (WA09 (H9) and BG01v) and 4 passages from 1 hES cell line (TE06 (I6)), EBs samples derived from WA09 cells at 4 different time points with replicates, and 5 types of adult cells (HUVEC, HMVEC, UASMC NHA, and LFB).

Transcriptomics and relative potency assessments using Bench Mark Dose of Bisphenol A, Bisphenol S, Bisphenol F, and 3,3',5,5'-Tetrabromobisphenol A in H9 human embryonic stem cells

Project description:In this study we used RNA-seq to characterize the dose-response for global transcriptomic alterations induced by BPA, BPF, BPS and TBBA in H9 (WA09) human embryonic stem (hES) cells. To assess the relative biological activity and potency of BPA and structural analogs BPS, BPF and TBBP, we examined the stem cell transcriptome in H9 hES cells following exposure to these chemicals at concentrations that covered greater than three orders of magnitude (1 microM to >100 microM). These exposure levels are considered to be near human relevant and range from noncytotoxic to overtly toxic. Overall, this study provides basic mechanistic information about the effects of BPA and structural analogs BPS, BPF and TBBP on the transcriptome of hES cells and demonstrates how these data can be applied to derive benchmark dose modeling (BMD) information useful for comparing relative potencies of these structurally related chemicals.

Short C-terminal Musashi-1 proteins regulate pluripotency states in embryonic stem cells

Project description:To understand the function of MSI1 in pluripotent stem cells, RNA-seq assays were performed on mouse embryonic stem cells R1, MSI1 knockout cell line R1-C5, human embryonic stem cells H9, RRM knockout cell line H9-C8, MSI1 full-length overexpression cell line H9-MSI1OE, MSI1C variant overexpression cell line H9-MSI1 (138-362) OE , H9-MSI1(272-362)OE. RNA bound by MSI1 in R1 and H9, and MSI1C variants MSI1 (138-362), MSI1(272-362) were detected using RIP-seq.

Expression data from undifferentiated human embryonic stem cells (hESC) and Day 3.5 mesodermal progenitor (CD326neg CD56+) population

Project description:Our understanding of how mesodermal tissue is formed, has been limited by the absence of specific and reliable markers of early mesoderm commitment. We report that mesoderm commitment from human embryonic stem cells (hESC) is initiated by Epithelial to Mesenchymal transition (EMT) as shown by gene expression profiling and by reciprocal changes in expression of the cell surface proteins, EpCAM/CD326 and NCAM/CD56. Molecular and functional assays reveal that CD326negCD56+ cells, generated from hESC in the presence of activin A, BMP4, VEGF and FGF2, represent a novel, multi-potent mesoderm-committed progenitor population. CD326negCD56+ progenitors are unique in their ability to generate all mesodermal lineages including hematopoietic, endothelial, mesenchymal (bone, cartilage, fat, fibroblast), smooth muscle and cardiomyocytes, while lacking the pluripotency of hESC. CD326negCD56+ cells are the precursors of previously reported, more lineage-restricted mesodermal progenitors. These findings present a novel approach to study how germ layer specification is regulated, and offer a unique target for tissue engineering. We used microarrays to compare gene expression profile of early mesodermal progenitors with undifferentiated hESC (H9 line). Mesoderm induction from hESC was initiatiated with combination of morphogens and growth factors including activin A, bone morphogenic protein 4, basic fibroblast growth factor and vascular endothelial growth factor. Proposed mesodermal progenitor population was isolated by FACS on day 3.5 of culture based on the presence of CD56 expression and the absenbce of CD326 expression.

Human ES cells reveal recurrent genomic instability at 20q11.21

Project description:By analyzing five human embryonic stem (hES) cell lines over long-term culture, we detected a recurrent genomic instability in the human genome. An amplification of 2.5â4.6 Mb at 20q11.21, encompassing about 23 genes in common, appeared in four cell lines of different origins. This amplification, which has been associated with oncogenic transformation, may provide a selective advantage to hES cells in culture Array-based comparative genomic hybridization, was performed on genomic DNA samples from different human embryonic stem cell lines, all cultured in our laboratory under the same conditions. VUB05-HD is an hES cell line carrying the Huntingtin mutant gene H1, H9, SA01, and VUB01 are various hES cell lines GSM341552 and GSM341553: SNP analysis GSM341589 to GSM341669: CGH analysis
