TOP STORY
TDP-43 Repression of Nonconserved Cryptic Exons Is Compromised in ALS-FTD
Investigators found that TDP-43 repressed the splicing of nonconserved cryptic exons, maintaining intron integrity. When TDP-43 was depleted from mouse embryonic stem cells, these cryptic exons were spliced into messenger RNAs, often disrupting their translation and promoting nonsense-mediated decay.

PUBLICATIONS (Ranked by impact factor of the journal)
Excessive Cellular Proliferation Negatively Impacts Reprogramming Efficiency of Human Fibroblasts
Scientists report that rapid proliferation of human somatic fibroblasts is detrimental to reprogramming efficiency when reprogrammed using a lentiviral vector expressing OCT4, SOX2, KLF4, and cMYC in insulin-rich defined medium. [Stem Cells Transl Med] Abstract

Human iPSC Derived Disease Model of MERTK-Associated Retinitis Pigmentosa
The authors report successful generation of human induced pluripotent stem (iPSC) cells from skin fibroblasts of a patient harboring a novel Ser331Cysfs*5 mutation in the MERTK gene. [Sci Rep] Full Article

Influence of Oriented Nanofibrous PCL Scaffolds on Quantitative Gene Expression during Neural Differentiation of Mouse Embryonic Stem Cells
Embryoid bodies, which contained all three embryonic germ layers, were cultured on poly Ɛ-caprolactone (PCL) scaffolds to study the effect of fiber orientation on cell morphology and differentiation. [J Biomed Mater Res A] Abstract

Dysregulation of the Transforming Growth Factor β Pathway in Induced Pluripotent Stem Cells Generated from Patients with Diamond Blackfan Anemia
Scientists generated induced pluripotent stem cells from diamond blackfan anemia (DBA) patients carrying RPS19 or RPL5 mutations. Transcriptome analysis revealed the striking dysregulation of the transforming growth factor β signaling pathway in DBA lines. [PLoS One] Full Article

Scriptaid Treatment Decreases DNA Methyltransferase 1 Expression by Induction of MicroRNA-152 Expression in Porcine Somatic Cell Nuclear Transfer Embryos
Researchers investigated the effects of Scriptaid on the development of porcine somatic cell nuclear transfer embryos in vitro and its mechanism. [PLoS One] Full Article

Metabolic Suppression during Mesodermal Differentiation of Embryonic Stem Cells Identified by Single-Cell Comprehensive Gene Expression Analysis
Researchers separated Flk-1+ and Flk-1 cells from spontaneously differentiating embryoid bodies of mouse embryonic stem cells. They found that cell aggregates derived from late stage Flk-1+ cells had a relatively small size and a low oxygen consumption rate compared with those derived from Flk-1 cells. [Mol Biosyst] Abstract | Graphical Abstract

Kinin-B1 and B2 Receptor Activity in Proliferation and Neural Phenotype Determination of Mouse Embryonic Stem Cells
Investigators showed that kinin-B1 and B2 receptors are differentially expressed in mouse embryonic E14Tg2A stem cells undergoing neural differentiation. [Cytometry A] Abstract

Conditionally Replicating Adenovirus Prevents Pluripotent Stem Cell–Derived Teratoma by Specifically Eliminating Undifferentiated Cells
Scientists demonstrated that conditionally replicating adenoviruses that specifically target cancers using multiple factors, originally developed as anticancer drugs, may also be useful as novel antitumorigenic agents in human pluripotent stem cell-based therapy.

REVIEWS
In Vitro T-Cell Generation from Adult, Embryonic, and Induced Pluripotent Stem Cells: Many Roads to One Destination
The authors discuss current methods for the in vitro derivation of T cells from murine and human hematopoietic stem/progenitor cells and human pluripotent stem cells that use feeder-cell and feeder-cell-free systems. They explore their potential for adoption for use in T-cell-based therapies. [Stem Cells] Abstract

POLICY NEWS
Obama Announces Nominees for NSF Deputy Director, Head of DOE Office of Science
The White House announced that President Barack Obama has nominated engineer Richard Buckius, currently the National Science Foundation’s (NSF’s) chief operating officer, to fill the agency’s second highest position: deputy director. [ScienceInsider] Editorial

Caution Urged over Editing DNA in Wildlife (Intentionally or Not)
The US National Academy of Sciences, Engineering, and Medicine held the first in a series of meetings meant to find ways to balance the promise and perils of the ‘gene drive’ technique. The method can rapidly modify not just a single organism but a whole population, by inserting a desired genetic modification into an organism along with DNA that increases the rate at which the change is passed to the next generation.
