Background The human-to-rat hematopoietic stem cell transplantation (HSCT) model is rare, unlike its human-to-mouse counterpart. rat models are desired, especially in areas of physiology, toxicology, and pharmacology. In addition to lymphocytes, macrophages also considered be important for xenotransplantation. We generated a xenotransplantation prove the role as barrier. Methods Immunodeficienc...
Varicella-zoster virus (VZV) disseminates in the body in peripheral blood mononuclear cells during chickenpox. Up to 1 in 10,000 mononuclear cells are infected during the viremic phase of the disease. We developed an in vitro system to infect human mononuclear cells with VZV by using umbilical cord blood. In this system, 3 to 4% of T cells were infected with VZV. VZV mutants unable to express c...
Cord blood hematopoietic stem cells are widely used as an alternative source for hematopoietic stem cells transplant. Increasing rate of patients who need hematopoietic stem cells transplant and many advantages of cord blood in comparison to bone marrow hematopoietic stem cells, have promoted banking of cord blood units. Cord blood banking requires accurate steps in donor selection, cord blood ...
Purpose: Mammalian target of rapamycin (mTOR)is important in hematopoiesis and affect cell growth,differentiation and survival. Although previous studies were identified the effect of cytokines on the mononuclear cells development however the cytokines effect on mTOR in cord blood mononuclear cells was unclear. The aim of this study was to evaluate mTOR expression in cord blood mononuclear and ...
s:3604:"During pregnancy, the placenta delivers "cord blood" to the baby through the umbilical cord serving as a lifeline of nourishment from the mother to baby. At birth, "cord blood" remains in the umbilical cord and placenta and until recently, had typically been discarded. The tragedy of this practice is that "cord blood" contains very special cells called "stem cells". Recent advances in m...
This study was designed to establish a more effective and safe culture system for adoptive immunotherapy by investigating the use of homologous cord blood plasma (HCBP) instead of fetal bovine serum (FBS), which has various limitations including ethical problems for the ex vivo expansion of human umbilical T lymphocytes. Fresh human umbilical mononuclear cell fractions were isolated by Ficoll-H...
OBJECTIVES Implantation of cell separation and mesenchymal stem cell culture techniques from human umbilical cord blood with and without using the Ficoll-Paque gradient density method (d=1.077 g/ml). METHODS Ten samples of the umbilical cord blood obtained from full-term deliveries were submitted to two different procedures of mesenchymal stem cell culture: a) Method without the Ficoll-Paque ...
BACKGROUND Umbilical cord blood (UCB) is an alternative source of hematopoietic stem cell transplantation (HSCT), used in Leukemia treatment. CD26+ cells, a fraction of CD34+cells, are a major population of UCB cells which negatively regulate the in vivo homing and engraftment of HSCs. CD26 is highly expressed in various cells such as HSCs, immune cells, fibroblasts, and epithelial cells. It ha...
