New High-Content Assay to Increase Human Embryonic Stem Cell Survival
Researchers from the Universities of Dundee, Glasgow and Heriot-Watt University, Edinburgh, have produced a high-content assay for human embryonic stem cell survival and used this to screen a range of libraries of ‘lead-like’ small molecules and known bioactives. [Press release from The Medical News discussing online prepublication in the Biochemical Journal]
Bioelectrical Signals Turn Stem Cells’ Progeny Cancerous
Biologists have discovered that a change in membrane voltage in newly identified “instructor cells” can cause stem cells’ descendants to trigger melanoma-like growth in pigment cells. The team also found that this metastatic transformation is due to changes in serotonin transport.

Scientists Create Australia’s First Diabetes Cells
In a major research advance, Melbourne researchers have created Australia’s first type 1 diabetes cells. Researchers created the diabetes cells using induced pluripotent stem cell technology. [Monash Institute of Medical Research Press Release]

Integrated Biochemical and Mechanical Signals Regulate Multifaceted Human Embryonic Stem Cell Functions
Feedback regulation and mechanical-biochemical integration provide mechanistic insights for the regulation of intercellular adhesion and cellular architecture in embryonic stem cells during long-term self-renewal. [J Cell Biol]
Genome-Wide Identification of Targets and Function of Individual MicroRNAs in Mouse Embryonic Stem Cells
Data suggest that miR-294 may promote pluripotency by regulating a subset of c-Myc target genes and upregulating pluripotency-associated genes such as Lin28. [PLoS Genet]
Production of Functional Glucagon-Secreting Alpha Cells from Human Embryonic Stem Cells
Results indicate that fully differentiated pancreatic endocrine cells can be created via step-wise differentiation of human embryonic stem cells. [Diabetes]
Somatic Cell Nuclear Reprogramming of Mouse Oocytes Endures Beyond Reproductive Decline
Researchers show that oocytes isolated from mice aged beyond the usual reproductive age yield ooplasts that retain reprogramming capacity after somatic nuclear transfer, giving rise to higher blastocysts rates compared to young donors ooplasts. [Aging Cell]
High-Content Screening of Feeder-Free Human Embryonic Stem Cells to Identify Pro-Survival Small Molecules
Researchers have developed a high-content assay for human embryonic stem cell survival and used this to screen a range of libraries of ‘lead-like’ small molecules and known bioactives. [Biochem J]
Human Pluripotent Stem Cells Produce Natural Killer Cells That Mediate Anti-HIV-1 Activity Utilizing Diverse Cellular Mechanisms
Researchers demonstrate derivation of functional natural killer (NK) cells from human induced pluripotent stem cells (iPSCs). More importantly, both human embryonic stem cell- and iPSC-derived NK cells are able to inhibit HIV-1 NL4-3 infection of CEM-GFP cells. [J Virol]
Nanofiber Matrices Promote the Neuronal Differentiation of Human Embryonic Stem Cell Derived-Neural Precursors In Vitro
Researchers cultured human neural precursors (NPs) derived from the NIH-approved embryonic stem line BGO1 on polycaprolactone fiber matrices of different diameter (i.e. nanofibers and microfibers) and orientation (i.e. aligned and random); fibers were coated with poly-L-ornithine/laminin to mimic the extracellular matrix and support the adhesion, viability and differentiation of NPs. [Tissue Eng Part A]
Transmembrane Potential of GlyCl-Expressing Instructor Cells Induces a Neoplastic-Like Conversion of Melanocytes via a Serotonergic Pathway
Data reveal glycine receptor chloride channel (GlyCl) as a molecular marker of a sparse and heretofore unknown cell population with the ability to specifically instruct neural crest derivatives, suggest transmembrane potential as a tractable signaling modality by which somatic cells can control stem cell behavior at considerable distance, identify a new biophysical aspect of the environment that confers a neoplastic-like phenotype upon stem cell progeny, reveal a pre-neural role for serotonin and its transporter, and suggest a novel strategy for manipulating stem cell behavior. [Dis Models Mech]
Enhanced Reprogramming and Cardiac Differentiation of Human Keratinocytes Derived from Plucked Hair Follicles, Using a Single Excisable Lentivirus
Researchers describe a detailed and reproducible method to derive induced pluripotent stem cells (iPSCs) from plucked human hair follicle keratinocytes. All emerging colonies were true iPSCs, with characteristics typical of human embryonic stem cells, differentiated into derivatives of all three germ layers in vitro and in vivo. [Cell Reprogram]

Just a Flesh Wound? U.K. Science Budget Spared Deep Cuts
The U.K. government’s long-awaited Comprehensive Spending Review was released, and it calls for a flat science budget over the next 4 years. While inflationary costs mean that the budget will likely see a cut of about 10% in real terms over that period, this scenario is far less dramatic than rumored cuts of 20% to 30% in real cash.
