Mice engrafted with human immune cells offer powerful in vivo model systems to investigate molecular and cellular processes of tumorigenesis, as well as to test therapeutic approaches to treat the resulting cancer. The use of umbilical cord blood mononuclear cells as a source of human immune cells for engraftment is technically straightforward, and provides T lymphocytes and autologous antigen-...
objective(s):immunosuppressive property of mesenchymal stem cells (mscs) has great attraction in regenerative medicine especially when dealing with tissue damage involving immune reactions. the most attractive tissue sources of human mscs used in clinical applications are bone marrow (bm), adipose tissue (at), and wharton's jelly (wj) of human umbilical cord. the current study has compared...
The finding of stem/progenitor cells in postnatal bone marrow and umbilical cord blood, opens up a possibility of using stem cells to treat neurologic diseases. There is a controversy, whether intravenously administered human umbilical cord blood cells (HUCBC) migrate to the brain, differentiate and improve recovery after ischemia. In this study, 1-3 x10;6 cells from non-cultured (non-committed...
introduction: effects of immediate tnf-α exposure on phenotype and function of dendritic cells (dcs) derived from cord blood mono nuclear cells materials and methods: umbilical cord blood mncs were isolated from healthy mothers and were divided into tnf(+( and tnf (-) groups. both were cultured using scf, flt3l, gm-csf and il-4. but, three ng/ml of tnf-α was first added in the culture of tnf(+(...
Recent evidence suggests that mononuclear cells (MNCs) derived from bone marrow and cord blood can differentiate into mesenchymal stem cells (MSCs) or outgrowth endothelial cells (OECs). However, controversy exists as to whether MNCs have the pluripotent capacity to differentiate into MSCs or OECs or are a mixture of cell lineage-determined progenitors of MSCs or OECs. Here, using CD133+/C-kit+...
objective oxygen intoxication plays an important role in the pathogenesis of some fetal diseases such as encephalopathy, ischemia& hypoxia. antioxidants can reduce oxidative damage in newborns. the object of this research was measuring total value of antioxidant and vitamin c in blood sample of pregnant women before delivery, and also in umbilical cord blood of their newborn, and repeating thes...
background: brain hypoxia-ischemia is a human neonatal injury that is considered a candidate for stem cell therapy. methods: the possible therapeutic potential of human umbilical cord blood (hucb) stem cells was evaluated in 14-day-old rats subjected to the right common carotid occlusion, a model of neonatal brain hypoxia-ischemia. seven days after hypoxia-ischemia, rats received either saline ...
background: considering the increasing rates of early hospital discharge and kernicterus in healthy full term newborns, timely identification of neonates at risk of severe hyperbilirubinemia is of great significance. the aim of this study was to investigate the predictive value of umbilical cord serum (ucs) bilirubin level for subsequent hyperbilirubinemia. moreover, we compared the predictive ...
