We analyzed the transcriptional profiles of differentiating mouse embryonic stem cells (mESCs) and show that embryoid bodies (EBs) sequentially expressed genes associated with the epiblast, primitive streak, mesoderm and endoderm of the developing embryo, validating ESCs as a model system for identifying cohorts of genes marking specific stages of embryogenesis. By comparing the transcriptional profiles of undifferentiated ESCs to those of their differentiated progeny, we identified 503 mESC and ...[more]

Expression data from control (F/F) and Snai1 knockout (KO) embryoid body (EB) and teratoma ™

Project description:Snai1 is a master factor of epithelial to mesenchymal transitioin (EMT), however, its role in embryonic stem cell (ESC) differentiation and lineage commitment remains undefined. We used microarrays to compare the global programme of gene expression between control and Snai1 knockout ESCs-derived EB and teratoma. For EBs, control and Snai1 knockout ESCs were cultured as embryoid bodies in spotaneous differentiation media, RNA of 5 days EBs were collected for Affymetrix microarrays. For teratomas, control and Snai1 knockout ESCs were injected into nude mice to form teratomas. RNA of 6 weeks were collected for Affymetrix microarrays.

Loss of Tet enzymes compromises proper differentiation of embryonic stem cells

Project description:Tet enzymes (Tet1/2/3) convert 5-methylcytosine (5mC) to 5-hydroxy-methylcytosine (5hmC) and are dynamically expressed in various embryonic and adult cell types. While loss of individual Tet enzymes or combined deficiency of Tet1/2 allows for embryogenesis, the effect of complete loss of Tet activity and 5hmC marks in development is not established. We have generated Tet1/2/3 triple knockout (TKO) mouse embryonic stem cells (ESCs) and examined their developmental potential. Combined deficiency of all three Tets depleted 5hmC and impaired ESC differentiation as seen in poorly differentiated TKO embryoid bodies (EBs) and teratomas. Consistent with impaired differentiation, TKO-ESCs contributed poorly to chimeric embryos and could not support embryonic development. Global gene expression and methylome analyses of TKO-EBs revealed promoter hypermethylation and deregulation of genes implicated in embryonic development and differentiation. These findings suggest a requirement for Tet- and 5hmC-mediated DNA demethylation in proper regulation of gene expression during differentiation of ESCs and development. To quantify global gene expression in differentiating embryoid bodies (EBs) derived from wild type (WT) and Tet triple knockout (TKO), TKO and WT mouse embryonic stem cells (ESCs) were differentiated in vitro to EBs and cultured for 10 days. RNA was extracted using Qiagen RNeasy kit and subjected to microarray analysis. Global gene expression profile of two technical replicas of WT embryoid bodies (2 samples in total) was compared to two technical replicas of two independent TKO embryoid bodies (4 TKO samples in total).

Expression data of control (F/F) and Snai1 knockout (KO) Flk1+/- cells

Project description:Snai1 is a master factor of epithelial to mesenchymal transitioin (EMT), however, its role in embryonic stem cell (ESC) differentiation and lineage commitment remains undefined. We used microarrays to compare the global programme of gene expression between control and Snai1 knockout Flk1+ and Flk1- cells sorted from 4 day EBs. Control and Snai1 knockout ESCs were cultured as embryoid bodies in spotaneous differentiation media, 4 days EBs were dissociated and sorted by anti-Flk1 antibody to separated Flk1+ and Flk1- cells, total RNA were collected for Affymetrix microarrays

Geminin represses mesendoderm cell fate acquisition in embryoid bodies

Project description:Geminin is a small nucleoprotein that neuralizes ectoderm in the Xenopus embryo. Geminin promotes neural fate acquisition of mouse embryonic stem cells: Geminin knockdown during neural fate acquisition decreased expression of neural precursor cell markers (Pax6, Sox1), while increasing expression of Pitx2, Lefty1 and Cited2, genes involved in formation of the mouse node. Here we differentiated mouse embryonic stem cells into embryoid bodies to study Geminin's ability to repress primitive streak mesendoderm fate acquisition. We used microarrays to define the sets of genes that are regulated by Geminin during cell fate acquisition in embryoid bodies, using Dox-inducible Geminin knockdown or overexpression mouse embryonic stem cell lines. ES cell lines for Geminin over-expression (GemOE) were treated without or with Dox from day 3 to day 5 of EB differentiation and were collected on days 4 or 5 for microarray analysis. Gem knockdown (KD) ES cell lines were treated without or with Dox from day 0 to day 4 of EB differentiation and were collected on day 4 for microarray analysis.

Expression file from FGF-10 experiment

Project description:Differentiating embryonic stem cells into cardiomyocytes is inefficient, and we discover that FGF-10 can induce embryonic stem cells differentiation into cardiomyocytes. We use microarray to gain insight into the global gene expression and elucidate the machenism that FGF-10 induces embryonic stem cells differentiation into cardiomyocytes. Two-day embryoid bodies were treated with or without 100 ng/ml FGF10 and RNA was obtained 24 hours later and hybridized by Affymetrix microarray
