Human Umbilical Cord Blood Mesenchymal Stem Cells Reduce Colitis in Mice by Activating NOD2 Signaling to COX2
Nucleotide-binding oligomerization domain 2 (NOD2) regulates intestinal inflammation, and is also expressed by human umbilical cord blood-derived mesenchymal stem cells (MSCs), to regulate their differentiation. Researchers investigated whether NOD2 is required for the anti-inflammatory activities of MSCs in mice with colitis. [Gastroenterology] Abstract

Paracrine Exchanges of Molecular Signals between Alginate-Encapsulated Pericytes and Freely Suspended Endothelial Cells within a 3D Protein Gel
Scientists developed a system for sustained and regulated delivery of paracrine signals by encapsulating living cells of one type in alginate beads and co-suspending these cell-loaded particles along with unencapsulated cells of a second type within a 3D protein gel. This system was applied to vascular tissue engineering by placing human placental microvascular pericytes in the particulate alginate phase and human umbilical vein endothelial cells in the protein gel phase. [Biomaterials] Abstract

The Role of Shear-Induced Transforming Growth Factor-β Signaling in the Endothelium
Human umbilical vein endothelial cells exposed to shear stress were compared with cells grown under static conditions. Signaling through the transforming growth factor-β receptor ALK5 was inhibited with SB525334. Cells were examined for morphological changes and harvested for real-time polymerase chain reaction, Western blot analysis, apoptosis, proliferation, and immunocytochemistry.

Therapeutic Effect of Transplanted Human Wharton’s Jelly Stem Cell-Derived Oligodendrocyte Progenitor Cells (hWJ-MSC-derived OPCs) in an Animal Model of Multiple Sclerosis
Scientists transplanted human Wharton’s jelly stem cell-derived oligodendrocyte progenitor cells into the brain ventricles of mice induced with experimental autoimmune encephalomyelitis, the animal model of multiple sclerosis. [Mol Neurobiol] Abstract

The Clinical Relevance of Pre-Formed Anti-HLA and Anti- Major-Histocompatibility-Complex Class I–Related Chain A Antigens Antibodies after Cord Blood Transplantation in Children
Investigators explored the role of anti-HLA antibodies on clinical outcomes in 70 pediatric patients who received a single unit of HLA mismatch cord blood for hematologic malignancies, immunodeficiencies or metabolic diseases. [PLoS One] Full Article

Transplantation of Human Cord Blood Mononuclear Cells and Umbilical Cord-Derived Mesenchymal Stem Cells in Autism
Stem cell transplantation may offer a unique treatment strategy for autism due to immune and neural dysregulation observed in this disease. This non-randomized, open-label, single center Phase I/II trial investigated the safety and efficacy of combined transplantation of human cord blood mononuclear cells and umbilical cord-derived mesenchymal stem cells in treating children with autism.

Isolation of c-Kit+ Human Amniotic Fluid Stem Cells from Second Trimester
Amniotic fluid-derived stem (AFS) cells have been described as an appealing source of stem cells because of their fetal, non-embryonic origin, easy access during pregnancy overcoming the ethical issues related both to the use of human embryonic cells and to the postnatal tissue biopsy with donor site morbidity, and their undemanding ability to be expanded. The authors and others have demonstrated the broad differentiation potential and they describe the established protocol they developed to obtain c-Kit+ human AFS cells, starting from second trimester amniocentesis samples.

Regulatory Potential of COUP-TFs in Development: Stem/Progenitor Cells
The authors highlight the progress of chicken ovalbumin upstream promoter transcription factors (COUP-TFs) function and its underlying mechanism in driving stem/progenitor cell self-renewal, lineage specification, differentiation, maintenance, and cell identity in diverse tissue types. [Semin Cell Dev Biol] Abstract

Mayo Clinic to Open Stem Cell Laboratory in Phoenix
Mayo Clinic in Arizona will open its own stem cell laboratory in summer 2014. The laboratory will be initially dedicated to storing and processing stem cells used for bone marrow transplants at Mayo Clinic Hospital and Phoenix Children’s Hospital.
