TECHNOLOGICAL DEVELOPMENTS

Genetic Crossroads
November 24th, 2003

In a potentially important development in techniques involving
embryonic stem cells, hundreds of cells have been grown
from a single cell taken from an early mouse embryo. Current
embryo-screening techniques work only for single-gene defects,
such as Tay-Sachs and cystic fibrosis. But if the mouse experiments
can be repeated with human embryos, it could become possible
to also screen for multi-gene, non-disease traits, thus opening
the door to increased eugenic selection, and potentially to
genetic "enhancement."
