Non-invasive method devised to sequence DNA of human eggs

Non-invasive method devised to sequence DNA of human eggs
Researchers have  for the first time determined the genome sequence of human egg cells without destroying them.

This could help couples who undergo in vitro fertilization (IVF) by allowing them to choose a genetically healthy embryo to implant into the mother without disturbing the embryo’s growth.

Colour-enhanced scanning electron micrograph of a human embryo at day 3. The egg has been fertilised in vitro and has developed to this stage in culture. The coat around the egg (zona pellucida) has been treated with acid Tyrodes solution to make a hole so an individual cell can be removed. This cell can then be used for genetic diagnosis before the embryo is transferred to the woman’s uterus. This allows the selective implantation of embryos that do not carry the genetic disease in question.
