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...

calcium crystals are evident in many parts of anther. there is little literature about differentiationof crystal-containing cells and crystal formation during anther development. petunia hybrid grandifloraflower buds collected at different developmental stages were fixed and studied. the results revealed thatyoung anthers are tetrasporangiate and in each of the four corners, the primary parieta...

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: mesenchymal stem cells (mscs) are multipotent cells that can be collected from different sources. under specific conditions, mscs can be differentiated to tissue specific cells in vitro. human umbilical cord mesenchymal stem cells (hucmscs) can easily be harvested and cultured in in vitro conditions. production of germ cells from mesenchymal stem cells is a very interesting and prom...

human diploid fibroblast cells produce a spectrum of necessary growth factors and extracellular matrix (ecm) components essential for growth and proliferation of a variety of other cell types. in this study, the effect of five human embryonic fibroblast cell lines, isolated from liver, lung, skin and foreskin tissues, was investigated. a coculture system analyse was employed to cloning efficien...

this paper summarizes the proceedings of a 1 day national symposium entitled “reproductive biology, stem cells biotechnology and regenerative medicine” held at shahid sadoughi university of medical sciences, yazd, iran on 3rd march 2016. here, we collected the papers that presented and discussed at this meeting by specialists that currently researched about the overlaps of the fields of reprodu...

objective(s): regulatory t cells, including cd4+cd25+fox3+ and cd8+cd28- cells play an important role in regulating the balance between immunity and tolerance. since multiple sclerosis is an inflammatory autoimmune disease, regulatory t cells are considered to be involved in its pathogenesis. in this study, we investigated the circulatory numbers of the two mentioned types of regulatory t cells...

multiple sclerosis (ms) is an autoimmune inflammatory demyelinating disease of the central nervous system. the aim of this study was to investigate the neuroprotective effects of transplanted human umbilical cord blood mesenchymal stromal cells (ucb-msc) derived neural progenitor cell (mdnpc) in eae, an experimental model of ms. to initiate neuronal differentiation of ucb-mscs, the pre-inductio...

introduction: transplantation of bone marrow stromal cells (bmscs) or schwann cells (scs) can increase axonal regeneration in peripheral nerve injuries. based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury . we pursued to evaluate the effects of bmscs and scs co-transplant...
