1.   Another is that no cells would be taken from human embryos or fetuses.

2.   But the Science article seems to be one of the first to report that embryonic cells were taken directly down a desired lineage by manipulation with growth factors.

3.   Cells are taken from a patient, grown in an external environment, and then inserted into the knee.

4.   Cells were often taken from cadavers or fetuses, and it was hard to get enough cells to treat many patients or to grow cells with a consistent quality.

5.   For example, Libby took cells from the arteries of rabbits and irritated them with a bacterial toxin.

6.   In a recent experiment, she took immune cells from the spleens of male and female mice and grew them in plastic plates in her laboratory.

7.   In a report in the journal Science, Niklason said she took smooth muscle cells, which strengthen vessel walls, from the arteries of pigs.

8.   In the hemophilia experiment, cells were taken from the patients, and genes to make a key blood clotting factor were inserted into the cells.

9.   In the other method, cells are taken from aborted fetuses, a use that the commission views as arguably equivalent to transplanting kidneys or corneas from a cadaver.

10.   Soon they plan to take those cells to the ICCB and test them against chemicals to see if any of them speed or slow the tumor-like behavior.
