Is the relinquishment and transfer of genetic parental rights in embryo
placement complicated by a lack of clarity regarding the parental status of the genetic couple?
Magli MC, Gianaroli L, Ferraretti AP; Chromosomal abnormalities in embryos
Identifying the symbolic component in embryo
research (and other biological controversies) is essential to sharpen debate and give competing considerations their due.
Their goal in embryo
splitting is to have one child (or sometimes possibly two), but they know there is the risk that a twin pregnancy will result.
The present culture regimes are known to cause changes in the embryos that may persist in embryo
In nonexposed embryos, we detected no luciferase activity with IVIS and barely any luciferase activity in embryo
This protects the human interests in embryo
diagnosis and acts as a brake to overeager expansion of embryo technologies.
Embryonic soluble HLA-G as a marker of developmental potential in embryos
Seeking to resolve this dilemma, Lanza and his colleagues looked to a technique commonly used to diagnose genetic diseases in embryos
A clone's DNA comes from one parent, whereas the DNA in embryos
produced by sexual reproduction comes from two parents--one set of chromosomes comes from each parent.
It is further believed that the developing embryo is more vulnerable to the effects of environmental estrogens than adult animals, but until now it has been difficult to determine these effects directly in embryos
Chromosomes in Embryos
Prior to In Vitro Fertilization Implantation
Midbody sealing after cytokinesis in embryos
of the sea urchin Arbacia punctulata.
The second molecule, Dkk-1, induces head formation in embryos
and was named after the German words for thick head.
Although neural crest-derived melanocytes were markedly altered in embryos
treated with estrogenic toxicants, expression of the early neural crest maker Xslug, a factor that regulates both the induction and subsequent migration of neural crest cells, was not affected, suggesting that the disruption induced by these compounds with respect to melanocyte development may occur at later stages of their differentiation.
