TOP STORYIn Vivo Genome Editing via CRISPR/Cas9 Mediated Homology-Independent Targeted Integration Based on clustered regularly interspaced short palindromic repeat/Cas9 (CRISPR/Cas9), technology, the authors devised a homology-independent targeted integration (HITI) strategy, which allows for robust DNA knock-in in both dividing and non-dividing cells in vitro and, more importantly, in vivo. As a proof of concept of its therapeutic potential, they demonstrated the efficacy of HITI in improving visual function using a rat model of the retinal degeneration condition retinitis pigmentosa.

PUBLICATIONS(Ranked by impact factor of the journal)Scientists recapitulated normal intestinal enteric nervous system development by combining human-pluripotent stem cells-derived neural crest cells (NCCs) and developing human intestinal organoids (HIOs). NCCs recombined with HIOs in vitro migrated into the mesenchyme, differentiated into neurons and glial cells and showed neuronal activity, as measured by rhythmic waves of calcium transients. [Nat Med] Abstract | Press Release In order to determine its efficacy with sustained release, heparin was covalently incorporated into degradable and non-degradable polyethylene glycol hydrogels. After in vitro characterization of their physicochemical properties, growth factor loaded, heparinized Type D gels were formed within the pores of porous polyurethane disks, which were then implanted and evaluated in a subcutaneous model. [Acta Biomater] Abstract Investigators found that the miR-101 expression level was significantly increased during the osteogenic differentiation of human bone marrow-derived mesenchymal stem cells. miR-101 depletion suppressed osteogenic differentiation, whereas the overexpression of miR-101 was sufficient to promote this process. They further demonstrated that enhancer of zeste homolog 2 (EZH2) was a target gene of miR-101. miR-101 also promoted in vivo bone formation by hBMSCs. [Sci Rep] Full Article Whether endometrial mesenchymal stem cells (EnSCs) endow innate anti-tumor properties on epithelial ovarian cancer (EOC) cells has never been reported. By using tumor-bearing animal model and ex vivo experiments, the authors found that EnSCs attenuated tumor growth by inducing cell cycle arrest, promoting apoptosis, disturbing mitochondria membrane potential and decreasing pro-angiogenic ability in EOC cells in vitro and/or in vivo. [Sci Rep] Full Article miR-9600 inhibited cell growth, hampered expression of cell cycle-related proteins and inhibited cell migration and invasion in human non–small-cell lung cancer cell lines. Further, miR-9600 significantly suppressed tumor growth in nude mice. [Mol Ther Nucleic Acids] Full Article Scientists described a method for isolation and expansion of fibroblastic-like, adherent ovine mesenchymal stromal cells (MSCs) that express CD44, CD90, CD140a, CD105 and CD166, and display trilineage differentiation potential. The osteogenic potential of MSCs derived following this methodology was further evaluated in vivo in a translational model of osteonecrosis of the femoral head, in which the persistence of grafted cells in the host tissue and their lineage commitment into osteoblasts and osteocytes was demonstrated by tracking enhanced green fluorescent protein-labelled cells. [J Tissue Eng Regen Med] Abstract Researchers evaluated the rate of improved response and outcome beyond day +100 after autologous stem-cell transplantation (ASCT), with and without maintenance therapy. One hundred and forty-four patients who underwent single ASCT with chemosensitive disease and achieved less than CR at day 100 post ASCT were evaluated. [Bone Marrow Transplant] Abstract Scientists prepared anti-vascular endothelial growth factor receptor 2 (VEGFR2) CAR-T cells by CAR-coding mRNA electroporation (mRNA-EP) and analyzed their immunological characteristics and functions for use in clinical research. The expression of anti-VEGFR2 CAR on murine and human T cells was detected with approximately 100% efficiency for a few days, after peaking 6–12 hours after mRNA-EP. Triple transfer of murine anti-VEGFR2 CAR-T cells into B16BL6 tumor-bearing mice demonstrated an antitumor effect comparable to that for the single transfer of CAR-T cells engineered with retroviral vector. [Mol Ther Oncolytics] Full Article Researchers examined whether Sirt1 overexpression mediated by adeno-associated viral vectors of serotype 1 (AAV1) specifically in skeletal muscle can counteract the development of insulin resistance induced by a high fat diet in mice. AAV1-Sirt1-treated mice showed up-regulated expression of key genes related to β-oxidation together with increased levels of phosphorylated AMP protein kinase.

SCIENCE NEWSImmunoCellular Therapeutics, Ltd. announced the presentation of updated immune monitoring data from the Phase II trial of ICT-107 in patients with newly diagnosed glioblastoma. Also presented were updated long-term survival data from the Phase I trial of ICT-107. ICT-107 is a dendritic cell-based immunotherapy targeting multiple tumor-associated antigens on glioblastoma stem cells. [Press release from ImmunoCellular Therapeutics, Ltd. discussing research presented at the Society for Neuro-Oncology Annual Meeting 2016, Scottsdale] Press Release Alexion Pharmaceuticals, Inc. announced that researchers presented new data from an analysis of patients enrolled in the Global atypical Hemolytic Uremic Syndrome (aHUS) Registry, demonstrating that initiation of Soliris® prior to kidney transplant reduces the risk of dialysis post-transplant in patients with aHUS. Specifically, results showed that starting Soliris prior to transplant reduced the likelihood of dialysis three-fold compared to initiating Soliris post-transplant.

INDUSTRY NEWSSalk Institute Awarded $25 Million Grant from Helmsley Charitable Trust The Salk Institute for Biological Studies has received a $25 million grant—a renewal of the largest research gift in the Institute’s 56-year history—that will be used to continue exploring an ambitious range of projects aimed at understanding the role chronic inflammation plays in driving human disease. [Salk Institute for Biological Studies] Press Release Morgridge–UW Project Investigates Tissue-Engineered Arteries for Transplant The prospect of creating artery “banks” available for cardiovascular surgery, bypassing the need to harvest vessels from the patient, could transform treatment of many common heart and vascular ailments. The Morgridge Institute for Research and the University of Wisconsin–Madison will address both the engineering and biomedical hurdles in this process through a five year, $8 million project funded by the National Heart, Lung, and Blood Institute. [University of Wisconsin–Madison (UW)] Press Release OrbusNeich Introduces a New Generation COMBO Plus Dual Therapy Stent for Active Healing OrbusNeich has announced the launch of its latest generation Dual Therapy Stent, the COMBO Plus.

POLICY NEWSCautious Welcome for UK’s Vague £2 Billion Research Pledge UK scientists have welcomed a surprise government promise to invest an extra £2 billion (US$2.5 billion) per year into research and development by 2020 – although details of the pledge will not be made clear for at least another two days. [Nature News] Editorial Conservatives, Liberals Team Up Against Animal Research “Painful, bizarre, and wasteful experiments.” Buying dogs “just to cut them apart … and kill them.” These statements might sound like the rhetoric used by extreme animal rights groups, but they come from White Coat Waste—a new, unlikely coalition of fiscal conservatives and liberal activists that aims to end federal funding for research involving dogs and other animals by targeting people’s pocketbooks in addition to their heartstrings.
