TOP STORY
Researcher, Colleagues Say Peripheral Blood Stem Cell Transplants from Unrelated Donors Associated with Higher Rates of Chronic Graft-versus-Host-Disease
Researchers conducted a two-year clinical trial comparing two-year survival probabilities for patients transplanted with peripheral blood stem cells or bone marrow stem cells from unrelated donors. While engraftment was faster in patients receiving peripheral blood stem cells, there was a higher incidence of overall chronic graft-versus-host disease in these patients than in those transplanted with bone marrow stem cells.

Efficient Direct Reprogramming of Mature Amniotic Cells into Endothelial Cells by ETS Factors and TGFβ Suppression
Investigators showed that human midgestation c-Kit lineage-committed amniotic cells (ACs) can be reprogrammed into vascular endothelial cells (rAC-VECs) without transitioning through a pluripotent state. Functionally, rAC-VECs form stable vasculature in Matrigel plugs and regenerating livers. [Cell]

Generation of Functional Blood Vessels from a Single c-kit+ Adult Vascular Endothelial Stem Cell
The authors provided evidence for adult vascular endothelial stem cells (VESCs) that reside in the blood vessel wall endothelium. A single transplanted c-kit-expressing VESC by the phenotype lin-CD31+CD105+Sca1+CD117+ can generate in vivo functional blood vessels that connect to host circulation.

In Vivo Maturation of Functional Renal Organoids Formed from Embryonic Cell Suspensions
Researchers constructed renal organoids from single-cell suspensions derived from E11.5 kidneys and then implanted these organoids below the kidney capsule of a living rat host. The implanted tissue exhibited physiologic functions, including tubular reabsorption of macromolecules, that gained access to the tubular lumen on glomerular filtration.

Bone Marrow Endothelial Progenitors Augment Atherosclerotic Plaque Regression in a Mouse Model of Plasma Lipid Lowering
To explore whether endothelial progenitors contribute to atherosclerosis regression, bone marrow endothelial progenitor cells (EPCs) from a transgenic strain expressing green fluorescent protein under the control of endothelial cell-specific Tie2 promoter were isolated. These cells were then adoptively transferred into atheroregressing Reversa recipients where they augmented plaque regression induced by reversal of hypercholesterolemia. [Stem Cells] Abstract

mTOR Complex-1 (mTORC1) and mTORC2 Play Different Roles in the Functional Survival of Transplanted Adipose-Derived Stromal Cells in Hindlimb Ischemic Mice via Regulating Inflammation In Vivo
Scientists investigated the role of mammalian target of rapamycin (mTOR) in the survival and therapeutic function of transplanted murine adipose-derived stromal cells in a murine peripheral arterial disease model. [Stem Cells] Abstract

Proinflammatory Macrophages Enhance the Regenerative Capacity of Human Myoblasts by Modifying Their Kinetics of Proliferation and Differentiation
Results showed that proinflammatory macrophages improve in vivo the participation of injected myoblasts to host muscle regeneration, extending the window of proliferation, increasing migration, and delaying differentiation. [Mol Ther] Abstract

Effective Delivery of Stem Cells Using an Extracellular Matrix Patch Results in Increased Cell Survival and Proliferation and Reduced Scarring in Skin Wound Healing
Investigators demonstrated the effectiveness of a stem cell therapy for improving wound healing in the skin and reducing scarring by introducing stem cells using a natural patch material. Adipose-derived stromal cells were introduced to excisional wounds created in mice using a non-immunogenic extracellular matrix patch material derived from porcine small intestine submucosa. [Tissue Eng Part A] Abstract

Functional Assessment of the Acute Local and Distal Transplantation of Human Neural Stem Cells after Spinal Cord Injury
Researchers hypothesized that acute transplantation of human fetal neural stem cells both locally at the injury site as well as distally via intrathecal injection would lead to improved functional recovery compared with controls. [Spine J] Abstract

Efficacy of Adoptive Cell Transfer of Tumor-Infiltrating Lymphocytes after Lymphopenia Induction for Metastatic Melanoma
A single-institution pilot clinical trial was performed combining nonmyeloablative chemotherapy and the adoptive transfer of tumor-infiltrating lymphocytes with interleukin-2 in patients with metastatic melanoma. [J Immunother] Abstract | Press Release

Suppression of Hepatocarcinoma Model In Vitro and In Vivo by ECRG2 Delivery Using Adenoviral Vector
To explore new strategies to fight against cancer, researchers systematically evaluated the therapeutic potential of esophageal cancer-related gene 2 (ECRG2) as a biological tool using adenoviral vector (Ad-ECRG2). In vivo experiments show a significant inhibition of cancer growth by intratumoral Ad-ECRG2 administration. [Cancer Gene Ther] Abstract

REVIEWS

Insulin Gene Therapy from Design to Beta Cell Generation
Enteroendocrine cells of the gastrointestinal track may be ideal targets for insulin gene therapy, but cell-targeting difficulties have limited practical implementation of insulin gene therapy for diabetes treatment. Therefore, recent gene transfer technologies developed to generate authentic beta cells through transdifferentiation are highlighted in this review. [Expert Rev Mol Med] Abstract
