Stem cells occur in many somatic tissues of multicellular organism and are important participants in their physiology. Stem cells have three distinctive properties: 1- self-renewal, 2- the potential to proliferate extensively and 3- capability to develop into multiple lineages. Every time a stem cell divides, it makes one exact copy and one progenitor cell. Progenitor cells have finite division...
introduction: umbilical cord blood is a rich source of hematopoietic cells and can be used in the clinical setting for hematopoietic cell transplantation in graft versus host disease (gvhd). a number of different drugs have been used as prophylaxis against gvhd including corticosteroids, cyclosporine a (cy a) and fk506. in this study, the in vitro effects of fk506 on cord blood mononuclear cell...
Background: Sickle cell disease is a genetic disorder of hemoglobin causing myriad of pathology including anemia. The purpose of this study was to evaluate the baseline values of steady state hemoglobin and packed cell volume as a guide to managing the early recognition of hemolytic crises in sickle cell anemia. Methods: A cross-sectional study was conducted among the sickle cell patients atte...
In a recent review of the literature (1,2), many of the problems dealing with cellular agglutination caused by ricin are presented and discussed. Although this phenomenon was first described in 1888 by Stilhnark, reactions involved in the agglutination of cells are poorly understood. The present report is concerned with factors which affect agglutination. Data are presented which show that eryt...
Background: There is evidence that mesangial cell structural changes contribute to the pathogenesis of diabetic nephropathy. To gain better insight into the mechanisms responsible for this issue, present study focused on effect of cord blood mononuclear cells (MNCs) derived CD133 positive cells on mesangial cell structure and function. Materials and Methods: The animals were randomly divided in...
