TOP STORY
Aged Human Cells Rejuvenated by Cytokine Enhancement of Biomaterials for Surgical Ventricular Restoration
Researchers investigated whether cytokine enhancement of a biodegradable patch could restore cardiac function after surgical ventricular restoration even when seeded with cells from old donors. [J Am Coll Cardiol]

New: Directed Differentiation of Pluripotent Stem Cells. A Cell Stem Cell Poster

 
PUBLICATIONS (Ranked by impact factor of the journal)

Large-Scale Screening Using Familial Dysautonomia Induced Pluripotent Stem Cells Identifies Compounds that Rescue IKBKAP Expression
Data implicated alpha-2 adrenergic receptor activity in regulating IKBKAP expression and demonstrated that small-molecule discovery using an induced pluripotent stem cell-based disease model can identify candidate drugs for potential therapeutic intervention. [Nat Biotechnol] Abstract | Press Release

Simple Precision Creation of Digitally Specified, Spatially Heterogeneous, Engineered Tissue Architectures
Complex architectures of integrated circuits are achieved through multiple layer photolithography, which has empowered the semiconductor industry. Researchers adapted this philosophy for tissue engineering with a versatile, scalable, and generalizable microfabrication approach to create engineered tissue architectures composed of digitally specifiable building blocks, each with tuned structural, cellular, and compositional features. [Adv Mater] Abstract | Press Release

Conditionally Reprogrammed Cells Represent a Stem-Like State of Adult Epithelial Cells
When conditionally reprogrammed cells from ectocervical epithelium or tracheal epithelium are placed in an air-liquid interface culture system, the cervical cells form a well differentiated stratified squamous epithelium, whereas the tracheal cells form a ciliated airway epithelium. Researchers discussed the diagnostic and therapeutic opportunities afforded by a method that can generate adult stem-like cells in vitro without genetic manipulation. [Proc Natl Acad Sci USA] Abstract | Press Release

A Randomized, Controlled Pilot Study of Autologous CD34+ Cell Therapy for Critical Limb Ischemia
Investigators evaluated the safety and efficacy of intramuscular injections of autologous CD34+ cells in subjects with moderate or high-risk critical limb ischemia, who were poor or noncandidates for surgical or percutaneous revascularization. [Circ Cardiovasc Interv] Abstract

Mesenchymal Stem Cells Overexpressing CXCR4 Improve Early Liver Regeneration of Small-for-Size Liver Grafts
Researchers investigated whether CXCR4-mesenchymal stem cell infusion protects hepatocytes and stimulates regeneration in 50% reduced-size liver transplantation. [Liver Transpl] Abstract

Expression of the Coxsackie Adenovirus Receptor in Neuroendocrine Lung Cancers and Its Implications for Oncolytic Adenoviral Infection
Scientists report that a high coxsackie adenovirus receptor (CAR) expression level in small cell lung cancer cell lines was found in vitro and in vivo when cell lines had been transplanted into immunodeficient mice. A correlation between CAR expression in the primary tumors and metastases development in the tumor model underlined the clinical relevance. [Cancer Gene Ther] Abstract

Injectable Polyethylene Glycol-Fibrinogen Hydrogel Adjuvant Improves Survival and Differentiation of Transplanted Mesoangioblasts in Acute and Chronic Skeletal-Muscle Degeneration
Researchers investigated the use of intra-muscular transplantation of mesoangioblasts (vessel-associated progenitor cells), delivered with an injectable hydrogel biomaterial directly into the tibialis anterior muscle of acutely injured or dystrophic mice. The hydrogel cell carrier, made from a polyethylene glycol-fibrinogen matrix, is polymerized in situ together with mesoangioblasts to form a resorbable cellularized implant. [Skelet Muscle] Abstract | Full Article | Press Release

Co-Injection of a Targeted, Reversibly Masked Endosomolytic Polymer Dramatically Improves the Efficacy of Cholesterol-Conjugated Small Interfering RNAs In Vivo
Effective in vivo delivery of small interfering RNA (siRNA) has been a major obstacle in the development of RNA interference therapeutics. One of the first attempts to overcome this obstacle utilized intravenous injection of cholesterol-conjugated siRNA (chol-siRNA). Investigators presented a new delivery approach that increases the efficacy of the chol-siRNA over 500-fold and allows over 90% reduction in target gene expression in mice and, for the first time, high levels of gene knockdown in non-human primates.

POLICY

France’s Young Researchers Protest ‘Precarious’ Contracts
Early-career researchers across France staged protests against a new national employment law aimed at reducing the number of public employees working on short-term contracts. The researchers say the new law is emptying French labs of young workers and bringing promising research careers to a standstill. [French National Research Agency, France] Press Release

Failed Summit Spares Research Bad News … For Now
European researchers can perhaps be thankful for one thing about the European Union budget negotiations: The participants were unable to strike a deal. The latest proposals for the innovation budget, which includes research and education funding, cut as much as 15% from the €164 billion proposed last year by the European Commission, the E.U. executive branch. [European Commission, European Union] Press Release

Mexican Scientists Pin Hopes on Incoming President
Enrique Peña Nieto will have his hands full when he becomes Mexico’s next president. But in his first year, Mexico’s research community is hoping that he will also put the country’s scientific house in order. To do that, he will need to boost science funding and re-energize Mexico’s scientific culture. [Mexican President, Mexico]
