The paper refers to Bogusław Wolniewicz’s deliberations on moral problems whicare being generated by cloning of human embryo cells which is one of the rapidly develop-ing biotechnological methods. The philosopher perceives serious moral dilemmas of using human embryos for experiments as in his opinion a human embryo is a human being.Although it is deeply immoral method, it is very unlikely that scientists will abandon it because the expectations of improving quality of human life or prolonging it, due to using genetic material, are great. What is more, cloning of embryo cells is closely linked with transplantations. Furthermore, the philosopher points out that such experiments are in their essence the same as doctor Mengele’s criminal experiments during World War II.
