3.   But Stupak argued that a nuclear transplanted cell could be implanted and could become a human being.

4.   Del Cerro responds that ERG tests may not be sensitive enough to detect electrical activity in the small area where the transplanted cells are.

5.   How the transplanted cells work is not known, and other researchers warned that concluding that the cells had changed would be premature.

6.   In addition, special coatings are being developed to protect transplanted cells from attack by the immune system.

7.   It may also yield clues as to whether changing the amount of transplanted cells or the location of the transplant could lead to a more successful therapy.

8.   The transplanted cells, which are types of stem cells, migrate to the site of damage and release factors that ameliorate or may even replace dead tissues.

9.   The transplanted cells, isolated from the pancreas, were harvested from deceased organ donors.

10.   These transplanted cells form easy-to-see lumps that become growing tumors.
