1.   Instead of using early-stage embryo cells, Wilmut used cells from the udder of an adult sheep.

2.   Already, these cells are used to treat leukemia victims and other severely ill patients whose immune systems are crippled by chemotherapy.

3.   Already, two such experiments have been completed in animals, using cells from fetuses rather than cells from adults.

4.   And at the University of Catania in Italy, researchers using immune cells from female rats succeeded in stimulating cell division with GnRH.

5.   And that similar cells were used to make the hepatitis A and rubella shots Parish got several years ago.

6.   Another curious feature of the system is that the same place cell may be used in more than one spatial map.

7.   Any researcher would retain ownership rights on new discoveries they make using the cells.

8.   Before the adult cell is used to start cloning, scientists could alter it.

9.   A battle is raging within the Bush administration over whether to prohibit federal support for biomedical research that uses cells derived from human embryos, federal officials say.

10.   About half the embryos made with cumulus cells began developing normally, as did about one-fourth of the embryos created using oviduct cells.
