Apoptosis in the human embryo.

The Effect of Nitric Oxide on Mouse Pre-Implantation Embryo Development and Apoptosis

Clinical studies have shown that in pathological conditions such as endometriosis and reproductive tract infection (male and female) there is an activation status of macrophages that produce large quantities of nitric oxide (NO) in addition to other effector molecules. Large amounts of NO may have embryotoxic roles and produce infertility. This study was designed to evaluate the effect of diffe...

In vitro versus In vivo: Development-, Apoptosis-, and Implantation-Related Gene Expression in Mouse Blastocyst

Background: While mammalian embryos can adapt to their environments, their sensitivity overshadows their adaptability in suboptimal in vitro conditions. Therefore, the environment in which the gametes are fertilized or to which the embryo is exposed can greatly affect the quality of the embryo and consequently its implantation potential. Objectives:</stro...

P-52: Brain-Derived Neurotrophic Factor Promotes The Development of Human Ovarian Early Follicles during Growth In Vitro

Background Cryopreservation of ovarian cortex is increasingly used to preserve fertility before cancer therapy. Recently, studies show that Brain-derived neurotrophic factor (BDNF) may be involved in oocyte maturation. Brain-derived neurotrophic factor (BDNF) is member of neurotrophin family that has anti-apoptotic effects on nervous system. Recent researches show that it also plays key role in...

I-34: Interactorme of Human Embryo Implan Implantation:Pathways,Networks

Background: A prerequisite for successful embryo implantation is adequate preparation of receptive endometrium and the establishment and maintenance of a viable embryo. The success of implantation further relies upon a two-way dialogue between the embryo and uterus. However, molecular bases of these preimplantation and implantation processes in humans are not well known. Materials and Methods: ...

Ethical Issues in Stem Cell Transplantation

There is great interest worldwide in discovering and developing a permanent source of tissues which would be capable of generating any cell type and which would avoid the problem of transplant rejection. Stem cells are cells that can specialize into the many different cells found in the human body. The ethical objections concerning stem cells have focused primarily on their source. Human embry...
