background: embryonic stem cells (esc) are pluripotent cells which have been used as a model to study the mechanism that control the embryogenesis and early mammalian development in vitro. the aim of this study was to isolate and produce embryonic stem cells from late blastocyst stage embryos in mice. materials and methods: blastocyst stage embryos from pregnant nmri mice were obtained and cult...

two basic and clinical researches accomplished during the recent years on embryonic and adult stem cells constituted a mutation in regenerative therapy. these cells can be used for treating some degenerative diseases. between them, age-related functional defects, hematopoietic and immune system disorders, heart failures, chronic liver injuries, diabetes, parkinson’s and alzheimer’s diseases, ar...

Background:Differentiation of Embryonic Stem Cells into Oocyte-like cells in vitro is challenging. Successful derivation of oocyte from stem cells can provide an alternative source for curing ovogenesis problems. The current study aims to demonstrate a new protocol with two different types of media for differentiating embryonic stem cells (ESCs) into oocyte-like cells ...

How has the development of human induced pluripotent stem cells (hiPSCs) modified the trajectory of stem cell research? Here, coauthorship networks of stem cell research articles and analysis of cell lines used in stem cell research indicate that hiPSCs are not replacing human embryonic stem cells, but instead, the two cell types are complementary, interdependent research tools. Thus, we conclu...

The embryonic stem cell-like gene expression signature has been shown to be associated with poorly differentiated aggressive human tumors and has attracted great attention as a potential target for future cancer therapies. Here, we investigate the potential of the embryonic stem cell signature as molecular target for the therapy and the strategy to suppress the embryonic stem cell signature. Th...

BACKGROUND Human embryonic stem cells are likely to play an important role in the future of regenerative medicine. However, exposure of existing human embryonic stem-cell lines to live animal cells and serum risks contamination with pathogens that could lead to human health risks. We aimed to derive an embryonic stem-cell line without exposure to cells or serum. METHODS Frozen cleavage-stage ...

Stem cells hold promise to treat diseases currently unapproachable, including Parkinson's disease, liver disease and diabetes. Seminal research has demonstrated the ability of embryonic and adult stem cells to differentiate into clinically useful cell types in vitro and in vivo. More recently, the potential of fetal stem cells derived from extra-embryonic tissues has been investigated. Fetal st...

RESEARCH QUESTIONS Couples undergoing IVF in Switzerland may have embryos in excess of their clinical need that they can donate to human embryonic stem cell research. Thus a new practice has emerged in Switzerland when IVF treatment and embryonic stem cell research come into contact. This interface needs to be investigated from an ethical-legal point of view to facilitate a fair informed choice...
