TOP STORY
Epilepsy Cured in Mice Using Brain Cells
University of California, San Francisco scientists controlled seizures in epileptic mice with a one-time transplantation of medial ganglionic eminence cells, which inhibit signaling in overactive nerve circuits, into the hippocampus, a brain region associated with seizures, as well as with learning and memory. Other researchers had previously used different cell types in rodent cell transplantation experiments and failed to stop seizures.

Functional Maturation of hPSC-Derived Forebrain Interneurons Requires an Extended Timeline and Mimics Human Neural Development
Researchers report the directed differentiation of human pluripotent stem cells (hPSCs) into medial ganglionic eminence (MGE)-like progenitors and their maturation into forebrain type interneurons. Both in vitro and posttransplantation into the rodent cortex, the MGE-like cells develop into GABAergic interneuron subtypes with mature physiological properties along a prolonged intrinsic timeline of up to seven months, mimicking endogenous human neural development.

Mining Exomic Sequencing Data to Identify Mutated Antigens Recognized by Adoptively Transferred Tumor-Reactive T Cells
To evaluate the potential association between the ability of tumor-infiltrating lymphocytes to mediate durable regressions and their ability to recognize potent antigens that presumably include mutated gene products, researchers developed a new screening approach involving mining whole-exome sequence data to identify mutated proteins expressed in patient tumors. [Nat Med] Abstract

3D Printed Bionic Ears
Researchers generated a bionic ear via 3D printing of a cell-seeded hydrogel matrix in the precise anatomic geometry of a human ear, along with an intertwined conducting polymer consisting of infused silver nanoparticles. This allowed for the in vitro culturing of cartilage tissue around an inductive coil antenna in the ear, which subsequently connects to cochlear-like electrodes. The printed ear exhibits enhanced auditory sensing for radio frequency reception, and complementary left and right ears can listen to stereo audio music. [Nano Lett] Abstract | Press Release

T Cells Expressing a Chimeric Antigen Receptor That Binds Hepatitis B Virus Envelop Proteins Control Virus Replication in Mice
In mice, scientists studied whether redirected T cells can engraft following adoptive transfer, without prior T-cell depletion, and whether the large amounts of circulating viral antigens inactivate the transferred T cells or lead to uncontrolled, immune-mediated damage. [Gastroenterology] Abstract

Highly Elastic Micropatterned Hydrogel for Engineering Functional Cardiac Tissue
Microfabrication techniques were applied to recombinant human tropoelastin, the resilience-imparting protein found in all elastic human tissues, to generate photocrosslinked biological materials containing well-defined micropatterns. The micropatterned hydrogels, produced through photocrosslinking of methacrylated tropoelastin, promote the attachment, spreading, alignment, function, and intercellular communication of cardiomyocytes by providing an elastic mechanical support that mimics their dynamic mechanical properties in vivo.

Cellular Immunotherapy for Carcinoma Using Genetically Modified EGFR-Specific T Lymphocytes
The anti-cancer potential of anti-Epidermal Growth Factor Receptor (EGFR) scFv was investigated based on cell-targeted therapy. A chimeric antigen receptor targeting EGFR was constructed and expressed on the cell membrane of T lymphocytes. These CAR-modified T cells demonstrated anti-tumor efficacy both in vitro and in vivo.

Role of Pericytes in Skeletal Muscle Regeneration and Fat Accumulation
Skeletal muscle from Nestin-GFP/NG2-DsRed mice show two types of pericytes, Nestin-GFP-/NG2-DsRed+ (type-1) and Nestin-GFP+/NG2-DsRed+ (type-2), in close proximity to endothelial cells. Type-2 pericytes participate in muscle regeneration, while type-1 contribute to fat accumulation. Transplantation studies indicate that type-1 pericytes do not form muscle in vivo, but contribute to fat deposition in the skeletal muscle, while type-2 pericytes contribute only to the new muscle formation after injury, but not to the fat accumulation.

Specificity Redirection by CAR with Human VEGFR-1 Affinity Endows T Lymphocytes with Tumor-Killing Ability and Anti-Angiogenic Potency
Investigators generated chimeric antigen receptor (CAR)-modified T lymphocytes with human vascular endothelial growth factor receptor-1 (VEGFR-1) specificity (V-1 CAR) by electroporation. The adoptive transfer of V-1 CAR T lymphocytes delayed tumor growth and formation and inhibited pulmonary metastasis in xenograft models and such efficacies were enhanced by cotransfer of T lymphocytes that expressed interleukin-15. [Gene Ther] Abstract

NKG2D CAR T-Cell Therapy Inhibits the Growth of NKG2D Ligand Heterogeneous Tumors
Researchers showed that adoptive transfer of T cells bearing a chimeric antigen receptor (CAR) inhibited the growth of target-expressing and -deficient tumor cells within ovarian and lymphoma tumors. [Immunol Cell Biol] Abstract

Generation of Integration-Free and Region-Specific Neural Progenitors from Primate Fibroblasts
Postnatal and adult human and monkey fibroblasts were infected with Sendai virus containing the Yamanaka factors for 24 hours, then they were cultured in a chemically defined medium containing leukemia inhibitory factor, transforming growth factor-β inhibitor SB431542, and glycogen synthase kinase-3β inhibitor CHIR99021 at 39°C for inactivation of the virus. Induced neural progenitor (iNP) colonies appeared as early as day 13 and can be expanded for >20 passages. Following transplantation into the forebrain, the iNP-derived cells retained the hindbrain identity. [Cell Reports] Abstract | Graphical Abstract | Press Release

REVIEWS
Regulation of Stem Cell Therapies Under Attack in Europe: For Whom the Bell Tolls
In this commentary, the authors discuss why only rigorous science and rigorous regulation can ensure translation of science into effective therapies rather than into ineffective market products, and mark, at the same time, the sharp distinction between the striving for new therapies and the deceit of patients.
