the european court lifted the italian ban on pre-implantation diagnostics (pgd). as such the court accepted pgd as a generally accepted means for medically assisted procreation, which may have consequences for other member states prohibiting pgd.
Pharmaceutical and chemical industries are facing new challenges for hazard and risk assessment from regulatory agencies. Especially for potential embryotoxicity of active compounds, conclusions from animal testing remain problematic due to numerous species-specific effects. Developmental toxicity screening preferentially should be performed with human material. Appropriate models are scarce or...
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Differentiated cells can change to embryonic stem cells by reprograming. Generation of induced pluripotent stem cells (iPSCs) has revolutionized the field of regenerative and personalized medicine. iPSCs can self-renew and differentiate into many cell types. iPSC cells offer a potentially unlimited source for targeted differentiation. Through the expression of a set of transcription factors, iP...

BACKGROUND Targeting stem cells holds great potential for studying the embryonic stem cell and development of stem cell-based regenerative medicine. Previous studies demonstrated that nanoparticles can serve as a robust platform for gene delivery, non-invasive cell imaging, and manipulation of stem cell differentiation. However specific targeting of embryonic stem cells by peptide-linked nanopa...
background: since embryonic stem (es) cells have the dual ability to proliferate indefinitely and differentiate into multiple tissue types, es cells could potentially provide an unlimited cell supply for human transplantation. objective: in order to study the differentiation of mouse embryonic stem (mes) cells, they were cultured in suspension by using es media without leukemia inhibitory facto...
Birth defects, which are in part caused by exposure to environmental chemicals and pharmaceutical drugs, affect 1 in every 33 babies born in the United States each year. The current standard to screen drugs that affect embryonic development is based on prenatal animal testing; however, this approach yields low-throughput and limited mechanistic information regarding the biological pathways and ...
