TOP STORY
Randomized Selection Design Trial Evaluating CD8+-Enriched Versus Unselected Tumor-Infiltrating Lymphocytes for Adoptive Cell Therapy for Patients with Melanoma
Patients with metastatic melanoma were prospectively assigned to receive unselected young tumor-infiltrating lymphocytes (TILs) versus CD8+-enriched TILs. All patients received lymphodepleting chemotherapy and high-dose interleukin-2 therapy and were assessed for response, toxicity, survival, and immunologic end points. [J Clin Oncol] Abstract

Megakaryocytes Promote Murine Osteoblastic HSC Niche Expansion and Stem Cell Engraftment after Radioablative Conditioning
Scientists demonstrated that host megakaryocytes function critically in expansion of the endosteal niche after preparative radioablation and in the engraftment of donor hematopoietic stem cells (HSCs). [Blood] Abstract

Engineering Bone Tissue Substitutes from Human Induced Pluripotent Stem Cells
Researchers induced three human-induced pluripotent stem cell (hiPSC) lines with different tissue and reprogramming backgrounds into the mesenchymal lineages and used a combination of differentiation assays, surface antigen profiling, and global gene expression analysis to identify the lines exhibiting strong osteogenic differentiation potential. They then engineered functional bone substitutes by culturing hiPSC-derived mesenchymal progenitors on osteoconductive scaffolds in perfusion bioreactors and confirmed their phenotype stability in a subcutaneous implantation model for 12 weeks.

IL-15 in Tumor Microenvironment Causes Rejection of Large Established Tumors by T Cells in a Noncognate T Cell Receptor-Dependent Manner
Investigators report that T cells eradicated two-week-old solid tumors that expressed IL-15, eliminating antigen-negative cells. In contrast, control tumors that lacked IL-15 expression consistently relapsed. Interestingly, even tumors lacking expression of cognate antigen were rejected when expressing IL-15, indicating that rejection after adoptive T-cell transfer was independent of cognate antigen expression. [Proc Natl Acad Sci USA] Abstract

Intracoronary Infusion of Allogeneic Mesenchymal Precursor Cells Directly following Experimental Acute Myocardial Infarction Reduces Infarct Size, Abrogates Adverse Remodeling and Improves Cardiac Function
The authors assessed the safety, feasibility and efficacy of intracoronary delivery of allogeneic mesenchymal precursor cells directly following acute myocardial infarction in sheep. [Circ Res] Abstract

Improved Cell Therapy Protocol for Parkinson’s Disease Based on Differentiation Efficiency and Safety of Hesc-, Hipsc and Non-Human Primate Ipsc-Derived DA Neurons
Researchers aimed to improve the safety of human- and non-human primate-iPSC (PiPSC)-derived dopaminergic (DA) neurons. PiPSC-derived NCAM+/CD29low DA-neurons were able to restore motor function of 6-OHDA lesioned rats 16 weeks after transplantation. [Stem Cells] Abstract

Tissue-Engineered Cardiac Patch for Advanced Functional Maturation of Human ESC-Derived Cardiomyocytes
Scientists investigated the effects of 3-dimensional tissue-engineered culture environment and cardiomyocyte purity on structural and functional maturation of human embryonic stem cell (ESC)-derived cardiomyocytes. [Biomaterials] Abstract | Press Release

Generation of a Hypomorphic Model of Propionic Acidemia Amenable to Gene Therapy Testing
Researchers generated an adult hypomorphic model of Propionic acidemia in Pcca mice using a transgene bearing an A138T mutant of the human PCCA protein. This adult model allowed gene therapy testing by intravenous injection with adenovirus serotype 5 and adeno-associated virus 2/8 vectors. [Mol Ther] Abstract

Novel Adenoviral Vector Induces T-Cell Responses Despite Anti-Adenoviral Neutralizing Antibodies in Colorectal Cancer Patients
In this phase I/II study, cohorts of patients with advanced colorectal cancer were immunized with escalating doses of E1-deleted adenovirus subtype 5 (Ad5) [E1-, E2b-]-carcinoembryonic antigen (CEA). CEA-specific cell-mediated immune responses were observed despite the presence of preexisting Ad5 immunity in a majority of patients. [Cancer Immunol Immunother] Abstract | Press Release

REVIEWS

Cell-Based Immunotherapy against Gliomas: From Bench to Bedside
Cellular immunotherapy is currently being explored as therapeutic approach to treat malignant brain tumors. This review discusses advances in active, passive, and vaccine-based immunotherapeutic strategies for gliomas both at the bench and in the clinic. [Mol Ther] Abstract

Cellular Immunotherapy for Plasma Cell Myeloma
Allogeneic hematopoietic cell transplantation for plasma cell myeloma can lead to graft-vs-myeloma immunity and long-term survivorship, but limited efficacy and associated toxicities have prevented its widespread use. Cellular immunotherapies seek to induce more specific, reliable and potent antimyeloma immune responses with less treatment-related risk than is possible with allogeneic transplantation.

POLICY

Pressure Builds on Congress to Kill NSF Bill
Several former top officials at the National Science Foundation (NSF) and the chairs of its oversight body yesterday wrote to Representative Lamar Smith (R-TX) urging him to withdraw a bill proposing changes to grant-making at the agency. That letter is signed by three previous NSF directors and three past chairs of the National Science Board, NSF’s presidentially appointed oversight body. The second letter, from 18 scientists who once headed individual research directorates at the agency, also argues that many of NSF’s most spectacular successes would not have qualified for funding under the terms of the legislation.

Canada to Convert NRC into ‘Toolbox’ for Industry
After two years of flogging the need to transform Canada’s National Research Council (NRC) into a toolbox for industry, the Conservative government announced that the 97-year-old agency is “open for business” under its new philosophy. Under the new policies, NRC scientists will tackle questions raised by individual businesses, while more basic research will be shuffled off to other departments or abandoned altogether. [National Research Council, Canada] Press Release

Russian Scientists Decry New International Funding Rules
Russian researchers are up in arms over a government decree issued which turns the process of issuing research grants into a bureaucratic nightmare for international foundations. The decree introduces new regulations according to which any organization that wants to award grants to Russian researchers must obtain permission from the Ministry of Education and Science for every grant.
