the aim of this study was to isolate mouse embryonic stem cells from late blastocyst stage embryos and to use them as a model system for the study of hematopoietic induction outside the embryo by coculturing of embryonic stem cells with bone marrow stromal cells. blastocyst stage embryos from pregnant nmri mice were obtained and cultured for 1-2 days in dmem medium. the inner cell masses formed...
background: endometriosis is a complex estrogen-dependent disease that is defined as the presence of endometrial gland and stroma outside the uterine cavity. although the exact mechanism for the development of endometriosis remains unclear, there is a large body of research data and circumstantial evidence that suggests a crucial role of estrogen in the establishment and maintenance of this dis...
introduction: there are the evidences to suggest that bone marrow stromal cells (bmscs) not only differentiate into mesodermal cells, but also adopt the fate of endodermal and ectodermal cell types. bmscs can be a valuable cell source as an autograph for clinical application involving regeneration of the central nervous system. bone marrow stromal cells can be expanded rapidly in vitro and have...
Background Endometriosis is the presence of endometrial tissue outside of the uterine cavity and is the most common gynecologic disorder in women of reproductive age. We have preliminary evidence that in the presence of a 3-dimensional (3-D) fibrin matrix, human endometrial glands, stroma, and neovascularization can develop in vitro, mimicking the earliest stages of endometriosis. The aim of th...
background susceptibility-weighted imaging (swi) is extremely sensitive in the detection of superparamagnetic iron oxide (spio) nanoparticle-labeled cells. however, no study has compared molecular imaging for stem cell detection using swi and other mri pulse sequences. objectives this study aims to assess the sensitivity of swi in detecting spio nanoparticle-labeled, human bone marrow-derived m...
introduction: considering the importance of co-culture in differentiation of embryonic stem cells, the aim of this study was evaluation of the effect of co-culturing fetal liver stroma cells with p19 cells on the line of differentiation. materials and methods: for this purpose, p19 cells were cultured directly in semisolid medium. these cells proliferated and primarily differentiated to colonie...
research about potential use of stem cells for the development of germ line cells in vitro had been challenged. in the present study, we reported a novel protocol consisting of cocktail growth factor addition for germ cell differentiation followed by transfection. the cells were purificated based on the expression on the cell surface of a protein. this protein is not present in normal cells of ...

objectives: periodontal tissue regeneration for treatment of periodontal disease has not yet been mastered in tissue engineering. stem cells, scaffold, and growth factors are the three main basic components of tissue engineering. periodontal ligament (pdl) contains stem cells; however, the number, potency and features of these cells have not yet been understood. this study aimed to isolate and ...
introdution: stroke is one of the most common diseases caused by occlusion or rupture of blood vessels in brain. it brings heavily loads for families and societies. although some new strategies including treatment of tissue plasminogen activator have been applied in the clinic, these methods do not have perfect effect. accordingly, more effective therapeutic strategies need to be developed. thi...
