introduction: type i diabetes mellitus is caused by autoimmune destruction of the insulin-producing β-cells. a new potential method for curing the disease is transplantation of differentiated insulin- secreting cells from human embryonic stem cells. methods: human embryonic stem cell lines (royan h1) were used to produce embryoid bodies. differentiation carried out by growth factor-mediated sel...
Purpose: Differentiation of mouse embryonic stem cells into Insulin secreting endocrine cells. Materials and Methods: In this study, Royan B1 mouse embryonic stem cell (derived from C57BL/6 mouse) were used. In directed differentiation method, embryonicstem cells after embryoid bodies formation were differentiated into insulin secreting cells. Nestin positive cells were obtained after culture ...

there are limited clinical investigations identifying the percentage of t helper 1 (th1) and t regulatory (treg) cells in stable as well as rejected kidney allografts, a concept which needs to be more studied. the aim of our study was to compare the percentage of cd4+ ifn-γ+ cells, the number of ifn-γ secreting cells and the amount of foxp3 expression in patients with or without stable graft fu...
Background and Objectives: Multiple sclerosis (MS) is an autoimmune neurodegenerative disease of the central nervous system (CNS). Although, the contribution of various cells such as B cells, CD8+ T cells, microglia/macrophages, dendritic cells, asterocytes and mast cells in the pathogenesis of MS have been demonstrated, however, it seems that autoreactive myelin specific CD4+ T cells pla...
Circulating antibody-secreting cells are present in the peripheral blood of healthy individuals reflecting continued activity humoral immune system. Antibody-secreting typically express CD27. Here we describe and characterize a small population class switched CD19+CD43+ B that lack expression CD27 subjects. In this study, characterized CD27-CD43+ cells. We demonstrate class-switched possess cha...
Objective(s): Neurotrophic factors secreting cells (NTS-SCs) may be a superior cell source for cell-based therapy in neurodegenerative diseases. NTS-SCs are able to secrete some neurotrophic Such as nerve growth factor and glia-derived neurotrophic factor. Our primary aim was to assess transplantation of neurotrophic factor secreting cells derived from human adipose-derived stem cells (hADSCs) ...
Introduction: The influence of morphine on pituitary secretion through µmu receptors has been nearly known. It is also reported that morphine has an effect on cell proliferation. In the present study we investigated the effect of morphine on the proliferation of acidophil cells of adenohypophysis in male rat. Method: This study has been carried out on 14 adult male Wistar rats divided into two ...
background: bone marrow has recently been recognized as a novel source of stem cells for the treatment of wide range of diseases. a number of studies on murine bone marrow have shown a homogenous population of rare stage-specific embryonic antigen 1 (ssea-1) positive cells that express markers of pluripotent stem cells. this study focuses on ssea-1 positive cells isolated from murine bone marro...
