TOP STORY
RNA Offers a Safer Way to Reprogram Cells
Researchers have shown, for the first time, that they can deliver reprogramming genes using RNA. This method could prove much safer than DNA-based reprogramming. [Press release from Massachusetts Institute of Technology discussing online prepublication in PLoS One]

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)
Patient-Specific Induced Pluripotent Stem-Cell Models for Long-QT Syndrome
Researchers generated patient-specific pluripotent stem cells from members of a family affected by long-QT syndrome type 1 and induced them to differentiate into functional cardiac myocytes. The patient-derived cells recapitulated the electrophysiological features of the disorder. [N Engl J Med]
Promotion of Direct Reprogramming by Transformation-Deficient Myc
Researchers report that the promotion of induced pluripotent stem cell generation by Myc is independent of its transformation property. [Proc Natl Acad Sci U S A]
Generation of Genetically Modified Rats from Embryonic Stem Cells
To monitor the pluripotency of rat embryonic stem cells, researchers generated Oct4-Venus transgenic rats via a conventional method, in which Venus is expressed by the Oct4 promoter/enhancer. [Proc Natl Acad Sci U S A]
Deletion of TDP-43 Down-Regulates Tbc1d1, a Gene Linked to Obesity, and Alters Body Fat Metabolism
Results establish that Tat activating regulatory DNA-binding protein (TDP-43) is critical for fat metabolism and embryonic stem cell survival. [Proc Natl Acad Sci U S A]
Synthesized Basement Membranes Direct the Differentiation of Mouse Embryonic Stem Cells into Pancreatic Lineages
On a synthesized basement membrane, mouse embryonic stem or induced pluripotent stem cells sequentially differentiated into the definitive endoderm, pancreatic progenitor cells, and then insulin-expressing pancreatic beta cells in vitro. [J Cell Sci]
Cell Line-Dependent Differentiation of Induced Pluripotent Stem Cells into Cardiomyocytes in Mice
Mouse induced pluripotent stem (iPS) cells differentiate into cardiomyocytes in a cell line-dependent manner. Trichostatin A induces myocardial differentiation in mouse iPS cells and might be useful to overcome cell line variation in the differentiation efficiency. [Cardiovasc Res]
The Efficient Generation of Induced Pluripotent Stem (iPS) Cells From Adult Mouse Adipose Tissue-Derived and Neural Stem Cells
Findings confirm that adipose tissue-derived cells are an ideal candidate as a readily accessible somatic cell type for high efficiency establishment of iPS cell lines. [Cell Transplant]
Involvement of Caveolin-1 in Fibronectin-Induced Mouse Embryonic Stem Cell Proliferation: Role of FAK, RhoA, PI3K/Akt, and ERK 1/2 Pathways
Researchers conclude that fibronectin stimulates mouse embryonic stem cell proliferation via RhoA-PI3K/Akt-ERK 1/2 pathway through caveolin-1 phosphorylation. [J Cell Physiol]
Application of Induced Pluripotent Stem (iPS) Cells in Periodontal Tissue Regeneration
iPS cells combined with enamel matrix derivative provide a valuable tool for periodontal tissue engineering, by promoting the formation of new cementum, alveolar bone, and normal periodontal ligament. [J Cell Physiol]
Innate Immune Suppression Enables Frequent Transfection with RNA Encoding Reprogramming Proteins
Researchers show that combined knockdown of interferon-beta (Ifnb1), Eif2ak2, and Stat2 rescues cells from the innate immune response triggered by frequent long-RNA transfection. Using this technique, they were able to transfect primary human fibroblasts every 24 hours with RNA encoding the reprogramming proteins Oct4, Sox2, Klf4, and Utf1. [PLoS One]

POLICY NEWS
NIH Takes on New Role in Fight Against Rare Diseases
A government program focusing on rare diseases, the Therapeutics for Rare and Neglected Diseases (TRND) program, has launched five pilot projects that are taking the National Institutes of Health in a new direction: developing drugs. TRND will work together with scientists, advocates and others to do the required research and testing on drugs before a compound can be tried in humans in a clinical trial. [National Institutes of Health, United States]
NIH Asks for Input on Closing Loophole in Conflict-of-Interest Rule
Responding to yet another flap about the influence of drug companies on biomedical research, the National Institutes of Health (NIH) has decided it needs more time to revise its rules for policing conflicts of interest so that sanctions will move with an investigator if he or she changes institutions.
