Making the most of a little DNA
New tests could make it easier to detect IVF embryos at risk of genetic disease.
A way of vastly amplifying the genome of a single cell is allowing unprecedented insights into the potential of embryos created during fertility treatment. Embryos can already be checked for some genetic abnormalities, but tests are limited by the tiny amount of DNA in a single cell removed from the embryo.

Comments
In regard to the following passage:
"Pre-implantation genetic diagnosis (PGD) is generally used by couples at risk of passing a serious genetic condition to their children. Embryos are created by in vitro fertilization (IVF) and at the 8-cell stage, one cell is taken for testing. If given the all-clear, the embryo is implanted into the mother's womb."
Are you kidding me? The synergetic effects of removing one cell of an eight cell stage are staggering. Am I getting this right? You re-implant the blastocyst, now with seven cells? Do you not get the mathematical consequences at the exponential level of the development of seven versus eight? The topological problems alone will probably result in deformation of significant areas of the resulting human organism.

taking one cell away from embryo at 8 celled stage for PCR would leave 1/8 cells less in embryo, to be implnated.
Can This deficit of 1/8th part of embryo not lead to some consequential problems, which at present are not envisaged.

Take a look at "The Wild Side," by Olivia Judson, which has appeared every weekday for four weeks on the New York Times website.

its a good news i thing im waiting for human cloning it will be possible in 2050 maybe? thanks for this news its really interesting.

The method also improves the testing for sex-linked disorders such as Duchenne muscular dystrophy (DMD).
