National polls continue to find that the majority of Americans favor embryonic stem cell research, although some surveys have found that that support has declined somewhat in recent years.

Many people object to the use of embryonic stem cells, contending that the research requires the destruction of potential life, because the cells must be extracted from human embryos.

The stem cells being used in the recently approved Geron trial were obtained from one of the Bush administration's approved stem cell lines. And no federal funds were used in the development of this treatment.

Since the restrictions on embryonic stem cell research took effect, many research institutions have redirected their focus to other types of stem cells, such as adult stem cells.

Adult stem cells can give rise to all the specialized types of cells found in tissue from which they originated, such as skin. But, scientists don't agree on whether adult stem cells may yield cell types other than those of the tissue from which they originate, according to the NIH.
