Well, there are two kinds of stem cells: adult stem cells, which you can get from any part of a grown body, and embryonic stem cells. These are the inner- core of days-old embryos that can develop into any kind of cell.

The first misconception is that embryonic stem cell research is not legal. The fact is, embryonic stem cell research is completely legal. Research on embryonic stem cells has taken place for years.

Adult stem cells tend not to form tumors.

The Stem Cell Research Enhancement Act would expand research on embryonic stem cells by increasing the number of lines stem cells that would be eligible for federally funded research.

Scientists have stated that embryonic stem cells provide the best opportunity for devising unique treatments of these serious diseases since, unlike adult stem cells, they may be induced to develop into any type of cell.

Stem cells are probably going to be extremely useful.
