Global gene expression profile of mouse ESC-2i, EpiSC-CHIR/XAV and EpiSC-FGF2/activin

ABSTRACT: The requirements for self-renewal differ between EpiSCs and ES cells and the underlying mechanism is largely unknown. Here we show that mouse EpiSCs can be efficiently derived and robustly propagated even from single cells, using two small-molecule inhibitors: CHIR99021 and XAV939. The whole-genome microarray analyses is performed to confirm the identity of EpiSC maintained in CHIR/XAV by comparing the expression profile in EpiSC-CHIR/XAV to those in ESC maintained in 2i and EpiSC maintained in FGF2/activin. Total RNA from ESC-2i, EpiSC-CHIR/XAV, and EpiSC-FGF2/activin were extracted for microarray analisys

Time-series of gene expression in female murine ES cells during EpiSC differentiation

Project description:Embryonic stem cells (ESC) are derived from the inner cell mass of the blastocyst in the presence of leukemia inhibitory factor (LIF). In vivo these cells then differentiate into epi stem cells (EpiSC) that can be derived from the Epiblast in presence of Fgf2 and ActivinA. In this study, female ESCs cultured in 2i medium have been differentiated into EpiSC for 3.5 days in vitro by addition of Fgf2 and Activin A. The gene expression profile was analyzed every 4-12 h using mouse exon arrays. Mouse Pgk12.1 ES cells were differentiated into EpiSC, samples were taken every 4-12 hours for 84 hours in total

Identify the downstream targets of CHIR99021 and XAV939 in EpiSC using microarray analysis

Project description:The requirements for self-renewal differ between EpiSCs and ES cells and the underlying mechanism is largely unknown. Here we show that mouse EpiSCs can be efficiently derived and robustly propagated even from single cells, using two small-molecule inhibitors: CHIR99021 and XAV939. To better define how CHIR and XAV act together to maintain EpiSC self-renewal, we performed microarray analyses to identify their downstream targets. The data show the genes regulated by addition of CHIR, XAV or both. EpiSCs starved in serum free growth medium (shown in growth protocol) for 12hrs were treated with CHIR (2hrs), XAV(4hrs), or both, after which total RNA was extracted for analysis.

Gene expression profiles of EpiSC-derived neural stem cell lines in comparison with EpiSC and embryonic CNS

Project description:Epiblast stem cells (EpiSCs) maintained in the medium with activin were freed from activin to elicit neural development, exposed to various strengths of Wnt signals, which may provide the initial stage of anteroposterior regional specificities, and placed in the culture condition to arrest neural development but expand cells as neural stem cells (NSCs) with epidermal growth factor (EGF) and fibroblast growth factor 2 (FGF2).

Global expression profiling of newly derived EpiSC lines

Project description:To characterize molecular features of new EpiSC lines established by the Wnt inhibition method, global gene expression profiles of the EpiSC lines were determined by microarray, and compared to those of EpiSC lines established by other group using the conventional method. Epiblasts, the source of the EpiSCs, and mESCs were also analyzed. EpiSCs and mESC were maintained as undifferentiated state on feeder layers. The stem cells were then separated from feeders, and RNAs were extracted from the stem cell lines. Embryonic tissues were manually dissected out from mouse embryos of E5.5, E6.5 or E7.5, from which RNAs were extracted.

RNA-seq of mouse embryonic stem cells differentiated to EpiSCs and further to presomitic mesoderm (PSM) via Wnt activation (CHIR99021) to study the influence of FGF signaling on PSM induction

Project description:Presomitic mesoderm (PSM) cells are the precursors of the somites, which flank both sides of the neural tube and give rise to the musculo-skeletal system shaping the vertebrate body. WNT and FGF signalling control the formation of both the PSM and the somites, and show a graded distribution with highest levels in the posterior PSM. We have employed reporter for the PSM control gene Tbx6 to investigate the differentiation of mouse ESCs from the naĂŻve state to PSM state. Feeder-free ESCs were seeded and grown on fibronectin (3-5 ng/ml)-coated plates in ESC medium containing LIF, PD0325901 and CHIR99021 (2i medium) to bring them to a naive state of pluripotency. Following this, the cells were brought to an EpiSC state by treating them with Activin A and FGF2. The EpiSC-like cells were then differentiated to PSM using CHIR99021 either alone or along with FGF ligands, FGF2 or FGF8 (Low concentration: 10 ng/ml or High concentration: 250ng/ml).
