STEM CELL RESEARCH
Ethical issues
Historically the use of stem cells in medical research has been controversial
This is because when the therapeutic use of stem cells first came to the public’s attention in the late 1990s, scientists were deriving human stem cells from embryos

2/ Many people disagree with using human embryonic cells for medical research because extracting the stem means destroying the embryo.
This creates complex issues, as people have different beliefs about what constitutes the start of human life.
For some people ...

3/ life starts when a baby is born, or when an embryo develops into a fetus. Others believe that human life begins at conception, so an embryo has the same moral status and rights as a human adult or child.

However, President Obama’s administration allowed for a partial rolling back of these research restrictions.

5/ ... do not derive these stem cells from embryonic stem cells. As a result, this technique does not have the same ethical concerns.
With this and other recent advances in stem cell technology, attitudes toward stem cell research are slowly beginning to change.

A better understanding of stem cells can provide insight into how these diseases arise and possible treatment options.
