Biomedical research
From ANIMAL PEOPLE, November 1993:
A George Washington University
research team revealed October 25 in
Science that it recently cloned and
destroyed a number of human embryos,
which were available for experimental use
because they had genetic flaws. It was the
most advanced genetic engineering experi-
ment to date using human tissue. The
announcement came less than a month after
300 scientists gathered in England to discuss
xenography––animal-to-human organ trans-
plants–– made theoretically possible after a
century of failures by implanting human genes
into animals raised as donors, which would
give the organs a human configuration and
help to overcome tissue rejection.
