It seems that you're in Germany. We have a dedicated site for Germany. For many years, the ethical discussion surrounding human embryonic stem cell research has focused on the moral status of the embryo.
The bioethics of stem cell research and therapy
Most cells in the body are differentiated cells. These cells can only serve a specific purpose in a particular organ. For example, red blood cells are specifically designed to carry oxygen through the blood. All humans start out as only one cell. This cell is called a zygote, or a fertilized egg. The zygote divides into two cells, then four cells, and so on.
Ethical Issues in Human Stem Cell Research: Embryos and Beyond
Ethics and Emerging Technologies pp Cite as. In this chapter, Inmaculada de Melo-Martin and Marin Gillis begin by presenting some background on embryonic stem cells, including on why their distinctive feature — the capacity to differentiate into any type of cell in the body — is thought to hold so much biomedical research and therapeutic potential. They then explore the ethical issues raised by the use of stem cells in research and treatment. Among the issues they discuss are: the moral status of the embryos that are destroyed in the derivation of stem cells; safety and informed consent by patients who undergo stem cell based therapies; obtaining ova from women to create embryos for research; and justice concerns related to the inequality in access to novel medical technologies.

The stem cell controversy is the consideration of the ethics of research involving the development and use of human embryos. Most commonly, this controversy focuses on embryonic stem cells. Not all stem cell research involves human embryos. For example, adult stem cells , amniotic stem cells , and induced pluripotent stem cells do not involve creating, using, or destroying human embryos, and thus are minimally, if at all, controversial. Many less controversial sources of acquiring stem cells include using cells from the umbilical cord, breast milk, and bone marrow, which are not pluripotent. For many decades, stem cells have played an important role in medical research, beginning in when Ernst Haeckel first used the phrase to describe the fertilized egg which eventually gestates into an organism.

Ethical Implications in the Use of Embryonic and Adult Neural Stem Cells
Metrics details. Rapid progress in biotechnology has introduced a host of pressing ethical and policy issues pertaining to stem cell research. In this review, we provide an overview of the most significant issues with which the stem cell research community should be familiar.
Manuel J. The new discoveries, the extraordinary dynamism in human stem cell SC research, and the great expectations of the benefits in clinical treatment of many diseases are on the edge of unparalleled advances in both: 1 the understanding of basic mechanisms of cell differentiation and development and 2 the translation from basic research to new clinical therapies. Human stem cells are obtained from different sources, such as embryo, fetal, and adult tissues, in vitro induction iPS cells or transdifferentiation. The evidence that these cells are pluripotent or multipotent , meaning they have the ability to differentiate into all body tissues or tissues of the same lineage, raises the possibility that they could regenerate diseased or damaged tissue in diseases that until now have had no effective treatments. Human stem cell research and therapy raise important bioethical considerations because of the human nature of these cells and their peculiar characteristics.

Translational Stem Cell Research
The advent and growth of technological advances have led to new routes of knowledge. Thereby, we currently face new challenges. We have just started to get a glimpse of the structural and functional role of neural stem cells in differentiation and migration processes, the origin of synaptic networks, and subsequent readjustments in specific circuits.
