Time Related Variations in Stem Cell Harvesting of Umbilical Cord Blood Scientists retrospectively analyzed cord blood donations collected from 1999 to 2011. Results from generalized multivariable linear mixed models showed that cord blood volume, total nucleated cells and CD34+ cell were associated with known obstetric and neonatal parameters and showed rhythmic patterns in different time domains and frequency ranges. [Sci Rep] Full Article Adapting Coculture In Vitro Models of the Blood-Brain Barrier for Use in Cancer Research: Maintaining an Appropriate Endothelial Monolayer for the Assessment of Transendothelial Migration The authors adapted an existing in vitro model of the human blood–brain barrier for use in studying cancer cell transmigration. The model is based on the coculture of endothelial cells (derived from cord blood hematopoietic stem cells) and brain pericytes. [Lab Invest] Abstract Hypoxic Conditioned Medium of Placenta-Derived Mesenchymal Stem Cells Protects against Scar Formation Researchers showed that hypoxic conditioned medium of placenta-derived mesenchymal stem cells (PMSCs) reduced scar formation in vivo and inhibited the proliferation and migration of skin fibroblasts in vitro. The level of IL-10 was affected by hypoxia, treatment with IL-10 mimicked the function of hypoxic conditioned medium of PMSCs and inhibition of IL-10 reversed the protective role of hypoxic conditioned medium of PMSCs. [Life Sci] Abstract Effect of Human Umbilical Cord Mesenchymal Stem Cell Transplantation in a Rat Model of Preeclampsia The authors tested the effects of human umbilical cord mesenchymal stem cell transplantation on reversing preeclampsia (PE) symptoms in a lipopolysaccharide-induced rat PE model. [Reprod Sci] Abstract Phenotypic and Functional Characterization of Mesenchymal Stem/Multipotent Stromal Cells From Decidua Parietalis of Human Term Placenta Investigators carried out an extensive characterization of decidua parietalis of human placenta. They report that these cells express and secrete a wide range of molecules with multiple functions. [Reprod Sci] Abstract Mesenchymal Stromal Cell-Derived Extracellular Vesicles Protect Against Acute Kidney Injury Through Anti-Oxidation by Enhancing Nrf2/ARE Activation in Rats Extracellular vesicles (EVs) isolated from the conditioned medium of human Wharton’s Jelly mesenchymal stromal cells and human foreskin fibroblast were intravenously injected in rats immediately after 45 min of unilateral kidney ischemia. They showed that renal tubular injury was alleviated and renal function was improved by mesenchymal stem cell-EVs. [Kidney Blood Press Res] Full Article |
