Death-Associated Protein Kinase 3 Mediates Vascular Inflammation and Development of Hypertension in Spontaneously Hypertensive Rats In human umbilical vein endothelial cells, expressions of vascular cell adhesion molecule 1, endothelial selectin, and cyclooxygenase 2, as well as reactive oxygen species (ROS) production induced by tumor necrosis factor-α, were inhibited by death-associated protein kinase (DAPK) inhibitor. Researchers demonstrated in cultured smooth muscle cells and endothelial cells that DAPK3 mediates tumor necrosis factor-induced inflammatory responses via ROS-dependent mechanisms. [Hypertension] Abstract Human Adipose Derived Stem Cells Enhance the Angiogenic Potential of Endothelial Progenitor Cells but Not of Human Umbilical Vein Endothelial Cells Data suggest that cellular communication occurs between adipose derived stem cells and endothelial progenitor cells (EPCs) triggered by cell-cell contact or at least close proximity which is partially mediated by secreted VEGF leading to the enhancement of angiogenic properties in EPCs but not in human umbilical vein endothelial cells. [Tissue Eng Part A] Abstract Umbilical Artery Chemokine CCL16 Is Associated with Preterm Preeclampsia and Fetal Growth Restriction Researchers investigated cord blood and placental immunoproteins in order to find new clues on pathogenetic factors of preterm preeclampsia. [Cytokine] Abstract Omentin Inhibits TNF-α-Induced Expression of Adhesion Molecules in Endothelial Cells via ERK/Nuclear Factor-κB Pathway Scientists investigated whether omentin affected the expression of intracellular adhesion molecule-1 and vascular cell adhesion molecule-1 in tumor necrosis factor-α (TNF-α) induced human umbilical vein endothelial cells. [Biochem Biophys Res Commun] Abstract Gene Therapy of Gastric Cancer Using LIGHT-Secreting Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells Researchers investigated the use of umbilical cord blood mesenchymal stem cells as carriers for a constant source of transgenic LIGHT to target tumor cells in vivo. [Gastric Cancer] Abstract Prospective Cohort Study About the Lymphocyte Subpopulations’ Change and Impact on the Pregnancy Outcome in Fetal Growth Restriction The percentage of B lmyphocyte in third trimester and CD4/CD8 ratio, kill cell activity in umbilical cord blood are associated with an increased risk of prematurity and SGA birth, but contrary result was found with the percentage and number of B lmyphocyte in cord blood. [J Matern Fetal Neonatal Med] Abstract Lead Acetate Reduces the Ability of Human Umbilical Cord Mesenchymal Stem Cells to Support Hematopoiesis In Vitro Researchers found that lead acetate has a toxic effect on the self-renewal, multipotent differentiation potential and hematopoiesis-promoting function of umbilical cord mesenchymal stem cells. [Mol Med Rep] Abstract Novel, High-Yield Red Blood Cell Production Methods from CD34-Positive Cells Derived from Human Embryonic Stem, Yolk Sac, Fetal Liver, Cord Blood, and Peripheral Blood The yield of cultured red blood cells can theoretically be maximized by amplifying the stem, progenitor, or precursor compartment. Researchers combined methods designed to expand these three compartments to optimize the yield of cultured red blood cells and found that exposing CD34+ cells to a short pulse of cytokines favorable for erythroid differentiation prior to stem cell expansion followed by progenitor expansion produced the highest yield of erythroid cells.
