the way to overcome current limitations in the generation of glucose-responsive insulin-producing cells is selective enrichment of the number of definitive endoderm (de) progenitor cells. sox17 is the marker of mesendoderm and definitive endoderm. the aim of the present research was to study the potential of sox17 knock-in cgr8 mouse embryonic stem (es) cells to differentiate into insulin produ...
background: the transcription factor oct-4, is an important marker of undifferentiating level and a key regulating factor for maintenance of pluripotency in cells. establishment of an oct-4 promoter-based reporter system is an appropriate tool for monitoring the differentiation of embryonic stem cells both in vivo and in vitro. methods: in the present study, we report construction of a recombin...
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...
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 ...
stem cells are the cells having some distinguishing characteristics like longevity, high capacity of self-renewal and differentiation, quiescence and highly error-free proliferation. almost all stem cells have the potential of lineage reprogramming, i.e. inter-conversion of cell lineages. they also have the potential to differentiate into almost all kinds of cells. these cells have been found i...
stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. they are found in multicellular organisms. in mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. in ad...
introduction: doxorubicin is frequently used for treatment of several types of cancer. doxorubicin cardiac toxicity has limited the use of this drug. corticosteroids may prevent doxorubicin induced cardiotoxicity. therefore the aim of this study was to evaluate mouse embryonic stem cells derived cardiomyocytes as a model to evaluate the effect of doxorubicin and dexamethasone. methods: mouse em...

germline and somatic stem cells are distinct types of stem cells that are dedicated to reproduction and somatic tissue regeneration, respectively. germline stem cells (gscs), which can self-renew and generate gametes, are unique stem cells in that they are solely dedicated to transmit genetic information from generation to generation. we developed a strategy for the establishment of germline st...
