Geneticists clone bull
From ANIMAL PEOPLE, March 1998:
BOSTON––Geneticists James Robl
of the University of Massachusetts and Steven
Stice of Advanced Cell Technology Inc. told
the International Embryo Transfer Society on
January 20 that they’d managed to clone some
prime Texas bull––the first bull ever cloned by
their method, believed to be the most efficient
of the three methods now experimentally tried.
Robl and Stice said the two offspring,
George and Charlie, represented in
Robl’s words, “a significant step” toward turning
genetically modified dairy cattle into walking
drug factories, who synthesize medicines in
their milk. But both cloned offspring are male.
Acknowledging that inconvenience, Robl and
Stice said they had several pregnant cows carrying
female cloned fetuses. The fetuses were
genetically altered to produce cows who eventually
should produce milk containing human
serum albumin, an important protein used in
maintaining hospital emergency blood supplies.
