Stem cell research has a lot of potential in terms of understanding underlying mechanisms of human development and differentiation, as well as the possibility of developing new treatments. Rapid advances in biotechnology have raised a slew of ethical and policy concerns about stem cell research. The ethical challenges that all researchers encounter during clinical translation begin with the requirement to ask a meaningful question, the answer to which has both scientific and social value and can be obtained by conducting the study as planned. In several of these areas, stem cell research may cause increased concern. Stem cell laws are the norms of law and policy that control the sourcing, research, and applications of stem cells in human medicine. These laws have sparked a lot of debate and differ greatly from country to country.
