TOP STORY

A Better Way to Grow Stem Cells 
Researchers have devised a synthetic surface that includes no foreign animal material and allows stem cells to stay alive and continue reproducing themselves for at least three months. [Press release from the Massachusetts Institute of Technology discussing online prepublication in Nature Materials]

SCIENCE NEWS

Stem Cells from the Thymus Reprogrammed to Become Skin Stem Cells
The study shows that stem cells from the thymus can function as hair follicle stem cells and contribute to the long-term maintenance of the skin. [Press release from the Medical Research Council Centre for Regenerative Medicine discussing online prepublication in Nature]

Stem Cell First
Researchers have created induced pluripotent stem cells from human skin without the use of viruses or genetic manipulation, an important step toward their eventual use in treating human disease. [Press release from the University of New South Wales discussing online prepublication in PLoS One]

CURRENT PUBLICATIONS  (Ranked by Impact Factor of the Journal)

Microenvironmental Reprogramming of Thymic Epithelial Cells to Skin Multipotent Stem Cells
Researchers show that the thymus of the rat contains a population of clonogenic thymic epithelial cells that can be extensively cultured while conserving the capacity to integrate in a thymic epithelial network and to express major histocompatibility complex class II molecules and Aire. [Nature]

Combinatorial Development of Biomaterials for Clonal Growth of Human Pluripotent Stem Cells
Researchers develop the first chemically defined, xeno-free, feeder-free synthetic substrates to support robust self-renewal of fully dissociated human embryonic stem and induced pluripotent stem cells. [Nat Mater]

Female Human iPSCs Retain an Inactive X Chromosome
Results indicate that human induced pluripotent stem cells (iPSCs) are epigenetically dynamic and do not display a pristine state of X inactivation with two active Xs as found in some female human embryonic stem cell lines. [Cell Stem Cell]

Canonical Wnt/Beta-Catenin Regulation of Liver Receptor Homolog-1 (Lrh-1) Mediates Pluripotency Gene Expression
Researchers present genetic, molecular, and pharmacological studies identifying a signaling axis in which beta-catenin promotes pluripotency gene expression in an Lrh-1-dependent manner. [Stem Cells]

High-Efficiency Induction of Neural Conversion in hESCs and hiPSCs with a Single Chemical Inhibitor of TGF-Beta Superfamily Receptors
Researchers identified compound C (also denoted as dorsomorphin), a protein kinase inhibitor, as a potent regulator of human embryonic stem cell (hESC) and human induced pluripotent stem cell (hiPSC) fate decisions. [Stem Cells]

A Role for Regulatory T Cells in Acceptance of Embryonic Stem Cell-Derived Tissues Transplanted Across an MHC Barrier
Researchers demonstrate that fully allogeneic embryonic stem cell-derived tissues are accepted with a regimen of coreceptor blockade even in recipients known to be relatively resistant to such a tolerizing protocol. [Stem Cells]

Generation of Microglial Cells from Mouse Embryonic Stem Cells
Researchers describe a basic protocol for the in vitro differentiation of mouse embryonic stem cells into microglial precursor cells. [Nat Protoc]

Factors from Human Embryonic Stem Cell-Derived Fibroblast-Like Cells Promote Topology-Dependent Hepatic Differentiation in Primate Embryonic and Induced Pluripotent Stem Cells
Researchers describe a novel in vitro differentiation model, and show that human embryonic stem cell (ESC)-derived fibroblast-like cell-secreted factors act in concert with regional features of ESC colonies to induce robust hepatic endoderm differentiation in primate pluripotent stem cells. [J Biol Chem]

A Combined Epigenetic and Non-Genetic Approach for Reprogramming Human Somatic Cells
Researchers report the first application of a combined epigenetic and non-genetic approach for reprogramming somatic cells, i.e., DNA methyltransferase and histone deacetylase inhibitors, and human embryonic stem cell extracts. [PLoS One]

Dynamic MicroRNA Expression Programs During Cardiac Differentiation of Human Embryonic Stem Cells: Role for miR-499
The data give significant insight into the regulatory networks that govern human embryonic stem cell (hESC) differentiation, and highlights the ability of microRNAs to perturb, and even control, the genes that are involved in cardiac specification of hESCs. [Circ Cardiovasc Genet]

Proteonomix, Inc. announced that it has executed a joint venture agreement with a group of investors that will create a new stem cell treatment and research facility in the United Arab Emirates. [Proteonomix, Inc. Press Release]
 
Stem Cell Agency Commits $243 Million, Expands Team Approach to Developing New Therapies
The Governing Board of the California Institute for Regenerative Medicine approved the concept for up to $243 million round of funding to move stem cell-based therapies to clinical trial. [California Institute for Regenerative Medicine Press Release]
