Stem cell and cloning studies bear promising potential in the field of regenerative medicine with their exciting and innovative features. The wide range of applications of these cellular treatments and their permanent repairing qualities foretell that a completely different scientific paradigm is emerging for the future. However, satisfactory insight has not yet been developed with respect to the moral status and legal aspects of these studies. Furthermore, their potentially untoward side effects are not understood well enough to compare with the benefits they provide for human life. In general, attempts are made to place the subject in a pattern composed of the sanctity of life, the unique characteristics of being an individual, the boundaries drawn by beliefs, and the basic principles of law. This article will discuss the benefits of stem cell and cloning studies as well as their undeveloped medical, ethical, religious, and legal aspects.
