TOP STORY
Researchers Regenerate Sensory Hair Cells, Restore Hearing to Noise-Damaged Ears
Researchers demonstrated for the first time that hair cells can be regenerated in an adult mammalian ear by using a drug to stimulate resident cells to become new hair cells, resulting in partial recovery of hearing in mouse ears damaged by noise trauma.

PUBLICATIONS (Ranked by impact factor of the journal)

RNA-Guided Human Genome Engineering via Cas9
Researchers engineered the type II bacterial clustered regularly interspaced short palindromic repeats system to function with custom guide RNA in human cells. Results establish an RNA-guided editing tool for facile, robust, and multiplexable human genome engineering. [Science] Abstract | Press Release

Dynamic Chromatin Remodeling Mediated by Polycomb Proteins Orchestrates Pancreatic Differentiation of Human Embryonic Stem Cells
Scientists profiled the transcriptome and select chromatin modifications at defined stages during pancreatic endocrine differentiation of human embryonic stem cells. In vivo– but not in vitro-differentiated endocrine cells exhibit close similarity to primary human islets in regard to transcriptome and chromatin structure. [Cell Stem Cell] Abstract | Graphical Abstract | Press Release

Molecular Imaging of the Paracrine Proangiogenic Effects of Progenitor Cell Therapy in Limb Ischemia
Using molecular imaging, the authors tested the hypothesis that treatment of limb ischemia with multipotential adult progenitor cells promotes recovery of blood flow through the recruitment of pro-angiogenic monocytes. [Circulation] Abstract

Intrathymic Progenitor Cell Transplantation across Histocompatibility Barriers Results in the Persistence of Early Thymic Progenitors and T Cell Differentiation
Researchers previously showed that the forced intrathymic (IT) administration of histocompatible hematopoietic stem cells can sustain long-term thymopoiesis in ZAP-70-immunodeficient mice. In the absence of conditioning, long term thymopoiesis by semiallogeneic progenitors was detected in IT, but not IV, transplanted mice. In IT-transplanted mice, ongoing thymopoiesis was associated with a ten-fold higher level of early thymic progenitors. [Blood] Abstract

Fetal Membrane Cells for Treatment of Steroid-Refractory Acute Graft-versus-Host Disease
Investigators tested fetal membrane cells for treatment of steroid-refractory acute graft-versus-host disease. [Stem Cells] Abstract

Intramuscular scAAV9-SMN Injection Mediates Widespread Gene Delivery to the Spinal Cord and Decreases Disease Severity in Spinal Muscular Atrophy Mice
Researchers investigated whether gene delivery to motor neurons (MNs) could also be achieved via intramuscular self-complementary (sc) AAV9 injection and subsequent retrograde transport along the MNs axons. Unexpectedly, they found that a single injection of scAAV9 into the adult mouse gastrocnemius mediated widespread MN transduction along the whole spinal cord, without limitation to the MNs connected to the injected muscle. [Mol Ther] Abstract

Endothelial Reconstitution by CD34+ Progenitors Derived from Baboon Embryonic Stem Cells
Researchers used a large non-human primate model, the baboon, to establish a step-wise protocol to generate CD34+ endothelial progenitor cells from embryonic stem cells and to demonstrate their reparative effects. [J Cell Mol Med] Abstract | Full Article | Press Release

Sickle Erythrocytes Target Cytotoxics to Hypoxic Tumor Microvessels and Potentiate a Tumoricidal Response
Investigators exploited a hitherto unrecognized ability of sickled erythrocytes (SSRBCs) but not normal RBCs (NLRBCs) to selectively target hypoxic tumor vascular microenvironment and induce diffuse vaso-occlusion. Within minutes after injection SSRBCs, but not NLRBCs, home and adhere to hypoxic 4T1 tumor vasculature with hemoglobin saturation levels at or below 10% that are distributed over 70% of the tumor space.

Biomimetic Three-Dimensional Anisotropic Geometries by Uniaxial Stretch of Poly(ɛ-Caprolactone) Films for Mesenchymal Stem Cell Proliferation, Alignment, and Myogenic Differentiation
Researchers present a novel simple, solvent-free, and reproducible method via uniaxial stretching for incorporating anisotropic topographies on bioresorbable films with ambitions to realize stem cell alignment control. Compared to unstretched films, human mesenchymal stem cells on uniaxial-stretched poly(ɛ-caprolactone) had larger increase in cellular alignment and elongation, without indication of cytotoxicity or reduction in cellular proliferation. [Tissue Eng Part C Methods] Abstract | Press Release

Combining T-Cell Immunotherapy and Anti-Androgen Therapy for Prostate Cancer
Investigators demonstrated that T cells can be genetically engineered to express a chimeric antigen receptor (CAR) targeting the tumor-associated antigen Muc1. CAR-Muc1 T cells were able to selectively kill Muc1-expressing human prostate cancer cells. [Prostate Cancer Prostatic Dis] Abstract

REVIEWS

IL-27 in Tumor Immunity and Immunotherapy
In this review, the authors argue that by virtue of its rate-limiting functions in innate and adaptive immune responses, modulating interleukin (IL)-27 holds considerable promise for future cancer immunotherapy. [Trends Mol Med] Abstract

Recent Developments in Oncolytic Adenovirus-Based Immunotherapeutic Agents for Use against Metastatic Cancers
This review focuses on the most recent updates in strategies to develop potent oncolytic adenovirus-based immunotherapeutics for use in cancer gene therapy. [Cancer Gene Ther] Abstract

SCIENCE NEWS

Stem Cells May Hold Promise for Lou Gehrig’s Disease
Apparent stem cell transplant success in mice may hold promise for people with amyotrophic lateral sclerosis, or Lou Gehrig’s disease. The study found that stem cell transplantation significantly extended the lifespan of the mice by 20 days and improved their neuromuscular function by 15 percent.

Mesoblast’s NeoFuse Stem Cell Product Shows Positive Results in Phase II Lumbar Spinal Fusion Trial
Mesoblast Limited announced that its Phase II clinical trial for lumbar spinal fusion had successfully met its safety and efficacy endpoints. The results suggest that Mesoblast’s NeoFuse product comprising allogeneic Mesenchymal Precursor Cells is as effective for interbody lumbar fusion as the gold standard, bone autograft, without the need for a second surgical procedure and its attendant morbidity risks.

Japan Stimulus to Boost Science
Japan’s government approved a plan to spend $116 billion to jump-start the economy and set the stage for long-term growth. Sources in the Japanese press are hinting that research on renewable energy and on stem cells could land a significant chunk of the new cash. [Japanese Government, Japan] Press Release

Surprise Choices Mark New Leadership on U.S. House Science Panel
High turnover is not unusual within the Committee on Science, Space, and Technology of the House of Representatives, which ranks low on the totem pole of powerful committees. Even so, Representative Lamar Smith, the new chair of the full 40-member committee, has made some surprising decisions in selecting the chairpersons of the panel’s six subcommittees.

George Huang of the University of Tennessee Health Science Center Continues Research for Root Canal Treatment with $1.8 Million Grant Funding
The concept of trying to regenerate growth of a tooth by inserting stem cell tissue has been around since the 60s, but little progress has been made. If Dr. Huang’s research is successful, the canals that have been cleared would be injected with stem cell tissue. Not only would this technique avoid the need for the rubber-like filling, it could actually stimulate healthy tissue growth, essentially rebuilding the tooth.
