objective: endothelial progenitor cells (epcs) have a potential application for cell therapy, however, their biological nature is not well-understood. epcs also possess some stemness features, such as their clonogenicity and differentiation capacity. the main aim of this study was to evaluate the expression of certain transcription factors regulating self-renewal property of stem cells. materia...

background: asphyxia is a common cause of perinatal mortality in 5-10% of all births worldwide. the present parameters for determining perinatal asphyxia, e.g. preeclampsia, cannot be considered as markers per se, and require auxiliary markers, e.g. increased number of nucleated red blood (nrbc) cells, for early diagnosis of perinatal asphyxia. objective: in this study, we evaluated the mean nr...

background: axotomy causes sensory neuronal loss. reconnection of proximal and distal nerve ends by surgical repair improves neuronal survival. it is important to know the morphology of primary sensory neurons after the surgical repair of their peripheral processes. methods: animals (male wistar rats) were exposed to models of sciatic nerve transection, direct epineurial suture repair of sciati...

The musculature of small lung veins, of the thoracic portion of the inferior vena cava, and of other thoracic veins of the mouse have been studied in the electron microscope. Tissues were fixed in 1 per cent osmium tetroxide buffered with veronal, to which either sodium chloride or sucrose had been added. Methacrylate or araldite served as embedding matrices. Phosphotungstic acid or uranyl acet...

In this study we examined the effect of mitogens and epidermal cells in inducing a Sézary cell morphology in normal peripheral blood lymphocytes. Peripheral blood mononuclear cells from six healthy volunteers were stimulated with the mitogens phytohemaglutinin and concanavalin A, and also cocultivated with human epidermal cell cultures. Incubation times with mitogens and epidermal cells were fo...

objectives: the study of erythropoiesis needs to develop the methods for erythroid progenitor cells (epcs) culture using stem cell potency to differentiate into variety of hematopoietic cells lineages. in this study, we induced differentiation of cord blood stem cells into erythroid progenitor cells in a semisolid culture media. materials and methods: cord blood mononuclear cells were isolate...

this experiment was conducted to investigate the effect of different levels of saccharomyces cerevisiae cell wall on performance, carcass traits and intestinal morphology in broilers. in this experiment 240 ross- 308 broilers were used in 4 treatments, 5 replicates and 12 bird in each replicate in a completely randomized design for 42 days. the treatments included: 1) control group (without sac...
