Is the use of excessive embryos from the IVF procedures for the research permitted ethically? Is the research to make human embryos in which their body parts are used for treatment of human diseases ethically permitted? Monday, May 22, 2017 Stem Cells and its potencies in the future/AAJ/Histologi-FKUI 45 BIOETHICAL ISSUES IN USING OF STEM CELLS The main issue is the resource of stem cell itself Embryonic stem (ES) cells are obtained commonly from several resource Cloning of human embryos in order to get the stem cells is the controversial issue abortion, the excessive embryo from IVF procedure and cloning process It has correlation with the issue of “the beginning of life” and the respect of life itself Cloning of human embryo is prohibited by all of the religions The procedures in harvesting the stem cells from human embryos will destroy the embryo and make the embryo to be death There is the argument that the status of human embryo is same with the human itself. All of the procedures in collecting the stem cells from human embryo are not permitted by the religion Monday, May 22, 2017 Stem Cells and its potencies in the future/AAJ/Histologi-FKUI 46 BIOETHICAL ISSUES IN USING OF STEM CELLS The status of human embryo is still debatable Does the human embryo has to be appreciated as the human it has a potency to be the human it is a part of human life Furthermore Is it true that the developing human embryo is an organism? Using of embryos obtained from the excessive human embryo in the IVF procedure are still controversy There is a moderate argument it is better to use those embryos in research and therapy of human diseases rather throw them away But it is also an other argument those embryos have to keep alive until they die naturally Monday, May 22, 2017 Stem Cells and its potencies in the future/AAJ/Histologi-FKUI 47 There is a fundamental question: Does the stem cell has a potency to become a cancer in the future?
