11.   Howley pointed out that the gene therapy technique raisesnone of the ethical or legal quandaries raised by using fetal cells.

12.   If it was a fetal cell that generated the Dolly clone, the outcome would not be startling because Wilmut had already demonstrated that fetal cells could be cloned.

13.   In a separate experiment, the investigators took the aged fetal cells that had grown in the laboratory and started to clone them.

14.   In an interview, Stice added that the group had now produced four additional live calves from genetically engineered fetal cells.

15.   In testing, about three tablespoons of amniotic fluid with discarded fetal cells are withdrawn from the uterus, cultured in the lab and inspected for abnormalities.

16.   In some patients, the fetal cells apparently grew too well.

17.   It is even easier to clone from fetal cells, Stice added.

18.   It is unlikely that thousands of patients will be getting fetal cells anytime soon, because the surgery is complicated and aborted fetuses are hard to obtain.

19.   More than a decade later, no therapy using fetal cells to treat any disease has reached the market.

20.   Olanow and his colleagues offered the man a fetal cell implant.
