| TOP STORY | Building the Tools that Fight Type 1 Diabetes A cure for type 1 diabetes has long eluded even the top experts. Not because they do not know what must be done – but because the tools did not exist to do it. But now scientists, harnessing the power of regenerative medicine, have developed a technique in animal models that could replenish the very cells destroyed by the disease.

| PUBLICATIONS (Ranked by impact factor of the journal) | Platelets Are Efficient and Protective Depots for Storage, Distribution, and Delivery of Lysosomal Enzyme in Mice with Hurler Syndrome Using a murine mucopolysaccharidosis type I model, scientists demonstrated that megakaryocyte/platelets were capable of producing, packaging, and storing large amounts of α-L-iduronidase (IDUA) with proper catalytic activity, lysosomal trafficking, and receptor-mediated uptake. IDUA can be released directly into extracellular space or within microparticles during megakaryocyte maturation or platelet activation, while retaining the capacity for cross-correction in patient’s cells. [Proc Natl Acad Sci USA] Abstract | Press Release Transplantation of Human Menstrual Blood Progenitor Cells Improves Hyperglycemia by Promoting Endogenous Progenitor Differentiation in Type 1 Diabetic Mice Scientists studied therapeutic effect of menstrual blood progenitor cells (MBPCs) and mechanism of β cell regeneration after MBPCs transplantation in type 1 diabetes mellitus model. Intravenous injection of MBPCs can reverse hyperglycemia and weight loss, prolong lifespan, and increase insulin production in diabetic mice. [Stem Cell Dev] Abstract Elimination of Contaminating Cap Genes in AAV Vector Virions Reduces Immune Responses and Improves Transgene Expression in a Canine Gene Therapy Model Researchers investigated the effects of elimination of cap gene transfer and of vector purification by CsCl gradient centrifugation on AAV vector immunogenicity and expression following intramuscular injection in dogs. [Gene Ther] Abstract Mesenchymal Stem Cells for Bronchopulmonary Dysplasia: Phase I Dose-Escalation Clinical Trial In a Phase I dose-escalation trial, investigators assessed the safety and feasibility of a single, intratracheal transplantation of human umbilical cord blood-derived mesenchymal stem cells in preterm infants at high risk for bronchopulmonary dysplasia. [J Pediatr] Full Article | Press Release Chitosan Scaffolds Containing Calcium Phosphate Salts and rhBMP-2: In Vitro and In Vivo Testing for Bone Tissue Regeneration The authors immobilized calcium phosphate salts and bone morphogenetic protein 2 (BMP-2) – combined or alone – into chitosan scaffolds using ISISA process. They analyzed whether the immobilized bone morphogenetic protein preserved its osteoinductive capability after manufacturing process as well as BMP-2 in vitro release kinetic. They also studied both the in vitro and in vivo biocompatibility of the resulting scaffolds using a rabbit model. [PLoS One] Full Article Mesenchymal Stem Cells Support Hepatocyte Function in Engineered Liver Grafts Researchers describe enhanced hepatic function achieved using a strategy of sequential infusion of cells and illustrate the advantages of co-cultivating bone marrow-derived mesenchymal stem cells with primary hepatocytes in the engineered whole-liver scaffold. [Organogenesis] Full Article Transplantation of Mesenchymal Cells Improves Peripheral Limb Ischemia in Diabetic Rats Investigators tested whether transplantation of adipose tissue-derived mesenchymal stromal cells into the ischemic muscular tissue of diabetic animals would attenuate impaired cell metabolism and microcirculatory function. [Mol Biotechnol] Abstract Transplantation of Photoreceptors Derived from Human Müller Glia Restore Rod Function in the P23H Rat Scientists aimed to differentiate human Müller glia with stem cell characteristics into photoreceptor cells by stimulation with growth and differentiation factors in vitro to upregulate gene and protein expression of CRX, NR2E3, and rhodopsin and various phototransduction markers associated with rod photoreceptor development and function and to examine the effect of subretinal transplantation of these cells into the P23H rat, a model of primary photoreceptor degeneration.
