Gene expression in undifferentiated human ES cells - Illumina

ABSTRACT: The application of human embryonic stem (ES) cells in medicine and biology has an inherent reliance on understanding the starting cell population. Human ES cells differ from mouse ES cells and the specific embryonic origin of both cell types is unclear. Previous work suggested that mouse ES cells could only be obtained from the embryo before implantation in the uterus1–5. Here we show that cell lines can be derived from the epiblast, a tissue of the postimplantation embryo that generates the embryo proper. These cells, which we refer to as EpiSCs (post-implantation epiblastderived ES cells), express transcription factors known to regulate pluripotency, maintain their genomic integrity, and robustly differentiate into the major somatic cell types as well as primordial germ cells. The EpiSC lines are distinct from mouse ES cells in their epigenetic state and the signals controlling their differentiation. Furthermore, EpiSC and human ES cells share patterns of gene expression and signalling responses that normally function in the epiblast. These results show that epiblast cells can be maintained as stable cell lines and interrogated to understand how pluripotent cells generate distinct fates during early development. *Note: EpiSCs were previously referred to as post-ES cells Keywords: cell type comparison

Novel cell lines from mouse epiblast share defining features with human embryonic stem cells

Project description:The application of human embryonic stem (ES) cells has an inherent reliance on understanding the starting cell population. Human ES cells differ from mouse ES cells and the specific embryonic origin of both cell types is unclear. Previous work suggested that mouse ES cells could only be obtained from the embryo prior to implantation in the uterus. Here we show that cell lines can be derived from the epiblast, a tissue of the post-implantation embryo that generates the embryo proper. These cells, which we refer to as EpiSCs (post-implantation epiblast-derived stem cells), express transcription factors known to regulate pluripotency, maintain their genomic integrity, and robustly differentiate into the major somatic cell types as well as primordial germ cells (PGCs). The post-ES cell lines are distinct from mouse ES cells in their epigenetic state and the signals controlling their differentiation. Furthermore, post-ES and human ES cells share patterns of gene expression and signalling responses that normally function in the epiblast. These results show that epiblast cells can be maintained as stable cell lines and interrogated to understand how pluripotent cells generate distinct fates during early development.

Metastable pluripotent states in NOD mouse derived ES cells

Project description:Embryonic stem (ES) cells are isolated from the inner cell mass (ICM) of developing blastocysts, whereas epiblast stem cells (EpiSCs) are derived from the post-implantation epiblast and are characterized by a restricted developmental potential. Although certain mouse strains, such as the non-obese diabetic (NOD) mice, are considered “non-permissive” for ES cell derivation, they retain the capacity to generate EpiSCs. Using the NOD strain as a model, we characterized the stability of pluripotent states in cells generated by ICM explantation or direct in vitro reprogramming. We find that ES-like NOD stem cells can be captured in both approaches by providing exogenous constitutive expression of Klf4 or c-Myc transcription factors or small molecules that can replace these factors during in vitro reprogramming. The fully pluripotent NOD ES and iPS cells appear “metastable”, as the cells acquire an alternative EpiSC-like identity after removal of the exogenous factors, while reintroduction of these factors converts the cells back to ICM-like pluripotency. Our findings suggest that stem cells from different genetic backgrounds can assume distinct states of pluripotency in vitro, the stability of which is regulated by endogenous genetic determinants and can be modified by the continuous presence of defined exogenous factors. Gene expression profiling was performed in mouse ES, EpiSC and EpiSC-like cell lines.

Developmental equivalence of epiblast stem cells (EpiSCs)

Project description:Epiblast stem cells (EpiSCs) were derived from the epiblast or the ectoderm (epi/ect) of pre-gastrula stage to late-bud stage mouse embryos. To identify if the EpiSCs retain any original stage specific characteristics or which developmental stage of epi/ect they most closely related to, we performed microarray analysis to compare the gene expression profile of multiple EpiSC lines with that of epi/ect of 7 different stages. Eighteen EpiSC lines established from R1-129 embryos of different stages and 1 line (EpiSC9) imported were harvested in triplicate cultured separately for 3 days. The * marks the subline thawed at a different time and harvested but originated from the same embryo. EpiSC9_T is an RNA sample provided by Dr Tesar. ESCs, iPSCs and MEFs were prepared accordingly. For the epiblast samples, in order to avoid the averaging effect by pooling samples, we linearly amplified the RNA starting from a single epiblast or ectoderm.

High-throughput screen in post-implantation haploid epiblast stem cells reveals Hs3st3b1 as a modulator for reprogramming

Project description:Epiblast stem cells (EpiSCs) derived from post-implantation epiblast are pluripotent stem cells, epigenetically distinct from embryonic stem cells (ESCs), which are widely used in reprogramming studies. Recent achieved haploid cell lines in mammalian open a new era for high-throughput genetic screening, due to their homozygous phenotypes. Here, we report the generation of mouse haploid EpiSCs (haEpiSCs) from post-implantation embryos at embryonic day 6.5 (E6.5). These cells maintain one set of chromosomes, express pluripotent and EpiSC specific genes, and have potentials to differentiate into three germ layers. We also develop a massive mutagenesis protocol with haEpiSCs, and subsequently perform reprogramming genetic screening using this mutation library. Multiple mutants related to various pathway modules are implicated. The validation experiment proves that Knock-out (KO) of Hst3st3b1 (One of the candidates) can promote reprogramming of EpiSCs to ground state efficiently. Our results open the possibility of utilizing haEpiSCs to uncover fundamental biological processes including cell fate alternations.

Isolation of epiblast stem cells from pre-implantation mouse embryos

Project description:Pluripotent stem cells provide a platform to interrogate control elements that function to generate all cell types of the body. Despite their utility for modeling development and disease, the relationship of mouse and human pluripotent stem cell states to one another remains largely undefined. We have shown that mouse embryonic stem (ES) cells and epiblast stem cells (EpiSCs) are distinct, pluripotent states isolated from pre- and post-implantation embryos respectively. Human ES cells are different than mouse ES cells and share defining features with EpiSCs, yet are derived from pre-implantation human embryos. Here we show that EpiSCs can be routinely derived from pre-implantation mouse embryos. The pre-implantation-derived EpiSCs exhibit molecular features and functional properties consistent with bona fide EpiSCs. These results provide a simple method for isolating EpiSCs and offer direct insight into the intrinsic and extrinsic mechanisms that regulate the acquisition of distinct pluripotent states.
