Sorry, no etymologies found.
If the blastomere is aneuploid, this molecular tool, called "fluorescence in situ hybridization," or FISH, will unmask it.
It turns out that our cells have been derived utilizing what we call a blastomere technology which means that we have been able to develop those stem cells without any embryo destruction, which somewhat mitigates the issues that have been in the media.
I think fewer people would be against blastomere research.
The blastomere technology has been reproduced and peer-reviewed on several occasions.
In August 2006, Advanced Cell Technology reported in the journal Nature that company scientists had successfully generated hESCs using its blastomere technology, an approach that does not destroy the developmental potential of embryos.
In addition to its blastomere research platform, Advanced Cell Technology has made progress on the therapeutic front.
Lanza counters this objection by saying that if the blastomere failed to divide, his group would send it off for PGD testing immediately, thereby salvaging the diagnostic procedure.
But other researchers disagree, saying that the removal of the blastomere poses unknown risks to the embryo and in turn, to the life of the child, should the embryo be implanted and continue developing to birth.
That exchange came to mind this week with news that stem-cell lines can be established from an early human embryo — a blastomere — without destroying it.
Size, similarity to extant embryos, regularity, uniformity of blastomere size, and the presence of multiple near-identical exemplars in the same samples.
