1.   In conclusion, the HPV DNA of colonic cancer cells can integrate and induce neogrowth in mouse cells.

2.   Another winner shows a cross section of a mouse tongue, with regions lit up in gold where a specific gene in the mouse cells has been activated.

3.   He shone infrared light onto a mixture of cell-sized latex beads and mouse fibroblast cells.

4.   He slipped a virus into mouse tumor cells.

5.   Human embryonic cells are expected to behave in the same general way as mouse cells, although few studies of them have been done.

6.   In fact, no one has been able to do this even with mouse cells.

7.   Last week the Washington Post reported that most of the stem cells cleared for federally funded research have been mixed in the laboratory with mouse cells.

8.   Most of these human cells were exposed to mouse cells while being coaxed to grow in the laboratory, to prevent them from developing prematurely.

9.   Most were grown on mouse cells, and there is always a risk that mouse viruses could contaminate the cells and harm any human who receives them.

10.   Researchers have routinely generated new strains of mice by manipulating mouse embryonic cells, and some aspects of this technology may prove useful for improving human embryonic cells.
