objective: spermatogonial stem cells (sscs) are the only cell type that can restore fertility to an infertile recipient following transplantation. much effort has been made to develop a protocol for differentiating isolated sscs in vitro. recently, three-dimensional (3d) culture system has been introduced as an appropriate microenvironment for clonal expansion and differentiation of sscs. this ...
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 positive 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 ce...
Twenty-two recipients of HLA-nonidentical living related and nonrelated renal allografts were studied for alterations in the relative percentage of OKT4-positive peripheral blood T-cells after transplantation. Characteristic shifts in the ratio of T-helper to T -suppressor/cytotoxic cells (TH/TS-C), but not absolute cell numbers, were demonstrated to correspond with the status of the allog...
Abstract Background and Objective: Identification of malignant cells and the type of malignancy in Effusionsis very important. The main aim of this study was to differentiate between reactive mesothelial cells and malignant cells and to determine the type of the tumor cells in effusions with the aid of tumor markers Creatine Kinase (CK), EMA and CEA. Material and Methods: Forty serous flui...
Peste des Petits Ruminants (PPR) is an acute, highly contagious, and febrile viral disease that affects both domestic and wild small ruminants. The disease has become a major obstacle to the development of sustainable Agriculture. Hemagglutinin (H), the envelope glycoprotein of Peste des Petits Ruminants Virus (PPRV), plays a crucial role in regulating viral adsorption and entry, thus determini...
neural stem cells (nscs) as a heterogeneous multipotent and self- renewal population are found in different areas in the developing mammalian nervous system, as well as the sub-ventricular zone (svz) and the hippocampus of the adult brain. nscs can give rise to neurons, astrocytes and oligodendrocytes. the aim of this study was to differentiate neural stem cells into noradrenergic–like cells in...
background: the present study was designed to evaluate the homing potential of mouse embryonic stem cells (esc) treated with erythropoietin (epo) in hematopoietic organs such as spleen and liver after transplantation using morphological and immuno-histochemical techniques. methods: day-four embryoid body (eb)-derived cells were dissociated and re-plated in medium in the presence and absence of ...
background: the interaction between follicular cells and oocyte leads to a change in gene expression involved in oocyte maturation processes. objective: the purpose of this study was to quantify the expression of more common genes involved in follicular growth and oocyte developmental competence. materials and methods: in this experimental study, the expression of genes was evaluated with qrt-p...
