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...

Introduction: Along with the use of stem cells technology, many jurisprudential, moral, and legal challenges have been created, including the exploitation of women, intentional abortion, conversion embryos into commodities, stem cells trade, breaking the human dignity, and threats caused by biological agents. Elimination of such possible consequences requires drafting laws and legal mechanisms ...

objective: the neural crest is a transient structure of early vertebrate embryos that generates neural crest cells (nccs). these cells can migrate throughout the body and produce a diverse array of mature tissue types. due to the ethical and technical problems surrounding the isolation of these early human embryo cells, researchers have focused on in vitro studies to produce nccs and increase t...
The extract of pluripotent stem cells induces dedifferentiation of somatic cells with restricted plasticity. In this study, we used the extract of human embryonic stem cells (hESC) to dedifferentiate adipose tissue-derived stem cells (ADSCs) and examined the impact of this reprogramming event on dopaminergic differentiation of the cells. For this purpose, cytoplasmic extract of ESCs was prepare...
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...
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...
