Alternative Splicing Regulates Mouse Embryonic Stem Cell Pluripotency and Differentiation
The findings herein illustrate a critical role for alternative splicing (AS) in the specification of embryonic stem cells with differentiation, and highlight the utility of global functional analyses of AS. [Proc Natl Acad Sci U S A]

SCIENCE NEWS

Study Sheds Light into the Nature of Embryonic Stem Cells
A study at the University of Edinburgh has shown that embryonic stem cells consist of cells that switch back and forth between precursors of different cell types. [Press release from EurekAlert! discussing online prepublication in PLoS Biology]

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

Functional Heterogeneity of Embryonic Stem Cells Revealed through Translational Amplification of an Early Endodermal Transcript
The data support a model in which embryonic stem cell culture has trapped a set of interconvertible cell states reminiscent of the early stages in blastocyst differentiation that may exist only transiently in the early embryo. [PLoS Biology]

A Model for Genetic and Epigenetic Regulatory Networks Identifies Rare Pathways for Transcription Factor Induced Pluripotency
Researchers have developed a computational model for the architecture of the epigenetic and genetic regulatory networks which describes transformations resulting from expression of reprogramming factors. Importantly, these studies identify the rare temporal pathways that result in induced pluripotent cells. [PLoS Comput Biol]

Long-Term Culture of Mouse Embryonic Stem Cells Derived Adherent Neurospheres and Functional Neurons
Researchers describe here a novel and efficient long-lasting protocol for in vitro embryonic stem cell differentiation into neuronal cells. [Tissue Eng Part C Methods]

Generation of Retinal Ganglion-Like Cells from Reprogrammed Mouse Fibroblasts
Researchers sought to determine whether induced pluripotent stem (iPS) cells express retinal progenitor cell related genes, and whether iPS cells can directly differentiate into retinal ganglion cells. [Invest Ophthalmol Vis Sci]

Homologous Recombination Conserves DNA Sequence Integrity Throughout the Cell Cycle in Embryonic Stem Cells
Relatively frequent homologous recombination utilizing homolog chromosome sequences preserves genome integrity in embryonic stem cells and has distinctive and important genetic consequences to subsequent somatic and germ cell lineages. [Stem Cells Dev]

PECAM-1, SSEA-1 and Flk-1 Mark Distinct Populations of Mouse Embryonic Stem Cells During Differentiation Towards Hematopoietic/Endothelial Cells
This work revealed a sequential change in platelet endothelial cell adhesion molecule-1 (PECAM-1), SSEA-1 and Flk-1 expression during embryonic stem (ES) cell differentiation, therefore they could be valuable cell surface markers for isolating cells at distinct developmental stages in ES cell differentiation. [Stem Cells Dev]

Telomerase Reverse Transcriptase (TERT) Related with Telomerase Activity Regulates Tumorigenic Potential of Mouse Embryonic Stem Cells
These results suggested that mTERT might be potentially beneficial as a biomarker, rather than oncogenes of somatic cells, for the assessment of embryonic stem cells tumorigenicity. [Stem Cells Dev]

Direct Generation of Induced Pluripotent Stem Cells from Human Non-Mobilized Blood
Generation of induced pluripotent stem cells from mononuclear cells of non-mobilized peripheral blood, with its relative efficiency and ease of harvesting, could enable the therapeutic use of patient-specific pluripotent stem cells. [Stem Cells Dev]

Bone Morphogenetic Protein 4 Mediates Human Embryonic Germ Cell Derivation
Here, researchers sought to determine whether recombinant human bone morphogenetic protein-4 could influence embryonic germ cell derivation and/or human primordial germ cell survival. [Stem Cells Dev]
