The question of cloning people and stem-cell research attracts great attention of scientists and causes debates in different societies. People are always wary of innovation in science and medicine and with the development of new technologies in the field of stem cells these fears are enhanced.

From my point of view it is a big opportunity to treat incurable diseases, built new neurons and organs. Every year millions of people suffer and die from the incurable diseases of the brain, heart, liver and kidney, which treatment could become easier with the use of stem cells. According to G. Wert and C. Mummery those cells, which were derived from embryos, have the ability to form cells of adult tissues and could play important role in its recovery and replacement. Therefore, it could be considered as the key to save lives of many serious ill persons and establish control over the development of cancerous tumours, develop efficient treatment of diabetes, infarct, diseases of bones and blood. Besides, as C. Jorgensen, D. Noel, F. Apparailly and F. Sany claim the regenerative potential of stem cells has been considered by scientists for a long time because of their ability to self-renew and specialize themselves to muscle, cartilage and bone recovery

Furthermore, Firstly, for many religious people the possibility of using stem cells depends on the answer to a question when a cell becomes a man. For instance, as K. Hug (2006) reports Protestants, Buddhists and Hindus permit the usage of embryos up to 14 days after fertilization; Jews and Muslims allow using human embryo up to 40 days after fertilization.
