Background and purpose: Spermatogenesis is a well-organized process that is influenced by a variety of factors. Alkaline phosphatase, and Gfra1, Lin28, and Sall4 genes are among the key players in this interconnected process. This study aimed to investigate the expression levels of Gfra1, Lin28, and Sall4 genes in embryonic, spermatogonial, and embryonic stem-like (ES-like) cells in mice. Mate...

Research and experimentation on embryonic stem cells has opened new horizons in different fields of medical science. The particular characteristic of these cells in its ability to produce different body cells has raised the hopes for treating a wide range of diseases and repairing damaged tissues. Alongside the progress in research and technology, a variety of legal challenges have also been po...

abstract introduction: cancer stem cells are a small subpopulation of cells within a tumor which are responsible for maintaining the tumor mass. a number of factors such as oct-4 that govern the fate of adult stem cells also play a role in malignant cell transformation. oct-4 is a key regulator of self-renewal in embryonic stem cells; its expression is potentially correlated with tumorigenesis ...

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 ...

background dox is a powerful chemotherapeutic agent used in the treatment of solid tumors and malignant hematological diseases. however, its cardiac toxicity limits the clinical usefulness of this drug. previous reports have shown corticosteroids induce a cytoprotective effect on cardiomyocytes. mouse transgenic embryonic stem cell-derived pure cardiomyocytes may be considered as a model for as...
