NANOG-Dependent Function of TET1 and TET2 in Establishment of Pluripotency
Whereas the genomic occupancy of NANOG has been extensively investigated, comparatively little is known about NANOG-associated proteins and their contribution to the NANOG-mediated reprogramming process. Using enhanced purification techniques and a stringent computational algorithm, researchers identified 27 high-confidence protein interaction partners of NANOG in mouse embryonic stem cells. They confirmed physical association of NANOG with ten-eleven translocation 1 (TET1), and demonstrated that TET1, in synergy with NANOG, enhances the efficiency of reprogramming.

Novel Interferon-Based Pre-Transplantation Conditioning in the Treatment of a Congenital Metabolic Disorder
The authors showed that type I IFN preconditioning, without irradiation or DNA alkylating agents, significantly enhanced the hematopoietic stem cell engraftment efficiency in wild type recipient mice. [Blood] Abstract

Astrocyte Pathology and the Absence of Non-Cell Autonomy in an Induced Pluripotent Stem Cell Model of TDP-43 Proteinopathy
Investigators generated functional astroglia from human induced pluripotent stem cells carrying an amyotrophic lateral sclerosis-causing transactive response DNA-binding protein (TDP-43) mutation and showed that mutant astrocytes exhibit increased levels of TDP-43, subcellular mislocalization of TDP-43, and decreased cell survival.

Autologous Adipose Tissue-Derived Stem Cells Treatment Demonstrated Favorable and Sustainable Therapeutic Effect for Crohn’s Fistula
In a Phase I clinical trial, adipose tissue-derived stem cells (ASCs) demonstrated their safety and therapeutic potential for healing fistulae associated with Crohn’s disease. This study was carried out to evaluate the efficacy and safety of ASCs in patients with Crohn’s fistulae. In this Phase II study, forty-three patients were treated with ASCs.

Enhancing Chemotherapy Response with Sustained EphA2 Silencing Using Multistage Vector Delivery
Researchers evaluated therapeutic efficacy of multistage vector-loaded EphA2 small inhibitory RNA with murine orthotopic models of metastatic ovarian cancers as a first step towards development of a new class of nanotherapeutics for the treatment of ovarian cancer. [Clin Cancer Res] Abstract | Press Release

Lentiviral Delivery of RNAi for In Vivo Lineage-Specific Modulation of Gene Expression in Mouse Lung Macrophages
Researchers report the use of lentiviral vectors for long-term in vivo delivery of RNA interference (RNAi) selectively to resident alveolar macrophages, key immune effector cells in the lung. They demonstrated the therapeutic potential of this approach by RNAi-based downregulation of p65, a component of the pro-inflammatory transcriptional regulator, nuclear factor κB and a key participant in lung disease pathogenesis. [Mol Ther] Abstract

Site-Specific Gene Delivery to Stented Arteries Using Magnetically Guided Zinc Oleate-Based Nanoparticles Loaded with Adenoviral Vectors
The authors hypothesized that novel zinc oleate-based magnetic nanoparticles loaded with adenovirus (Ad) would enable effective arterial cell transduction by shifting vector processing to an alternative pathway, protect Ad from inactivation by neutralizing factors, and allow site-specific gene transfer to arteries treated with stent angioplasty using a two-source magnetic guidance strategy. [FASEB J] Abstract

Recovery of Behavioral Symptoms in Hemi-Parkinsonian Rhesus Monkeys through Combined Gene and Stem Cell Therapy
Neuronal-primed adipose mesenchymal stem cells derived from rhesus monkey combined with adenovirus containing Neurturin and tyrosine hydroxylase were implanted into the striatum and substantia nigra of methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine-lesioned hemi-parkinsonian rhesus monkeys. [Cytotherapy] Abstract

Adipose Stromal Cells Primed with Hypoxia and Inflammation Enhance Cardiomyocyte Proliferation Rate In Vitro through STAT3 and Erk1/2
Researchers demonstrated that adipose derived stromal cells enhance the proliferation rate of rat neonatal cardiomyocytes and adult HL-1 cardiomyocytes in a paracrine fashion. [J Transl Med] Abstract | Full Article

Neural Progenitors Derived from Human Induced Pluripotent Stem Cells Survive and Differentiate Upon Transplantation into a Rat Model of Amyotrophic Lateral Sclerosis
Investigators analyzed the fate of human induced pluripotent stem cell (iPSC)-derived neural progenitors transplanted into the spinal cord of wild-type and transgenic rats carrying a human mutated SOD1(G93A) gene. The aim was to follow survival and differentiation of human neural progenitors until day 60 post-transplantation in two different in vivo environments, one being amyotrophic lateral sclerosis-like. iPSC-derived neural progenitors efficiently engrafted in the adult spinal cord and survived at high numbers.

REVIEWS

The Endogenous Regenerative Capacity of the Damaged Newborn Brain: Boosting Neurogenesis with Mesenchymal Stem Cell Treatment
Researchers discuss the endogenous capacity of the neonatal brain to regenerate after a cerebral ischemic insult. Furthermore, they consider the potential to use stem cell transplantation as a means to boost endogenous neurogenesis and restore brain function. [J Cereb Blood Flow Metab] Abstract

Targeted Therapy in Renal Cell Carcinoma: Moving from Molecular Agents to Specific Immunotherapy
Non-specific immunotherapy has been for a long time a standard treatment option for patients with metastatic renal cell carcinoma but was redeemed by specific targeted molecular therapies, namely the VEGF and mTOR inhibitors. Recent steps in the development of immunotherapy strategies are discussed in this review with a special focus on peptide vaccination which aims at a tumor targeting by specific T lymphocytes.

Europe Scales Back Research Plans
The ambitious vision for Europe’s next research program dimmed when heads of the 27 member states of the European Union agreed to slash the overall budget for 2014-20, at the end of a long and acrimonious meeting. The deal scales back the budget proposed by the European Commission for its Horizon 2020 research program by about 13%, to €69.24 billion, and means that the first year of the new program will have a smaller budget than the last year of the previous one.
