Using human embryos for any purpose other than to allow it grow into a baby is highly controversial and unethical. It disfigures human dignity. Destroying a human embryo either of the in-vivo or the surplus in vitro or of the cloned one to provide a cure for a disease is wholly unacceptable and morally evil. Human dignity cannot be sacrificed at the altar of research laboratories. Therefore “it is wrong to destroy embryos of any gestational age, for any purpose,” for “human life develops itself not something unto humans, but as humans.”

Research Objectives and Core Themes
This work examines the ethical controversy surrounding embryonic stem cell research (SCR), specifically focusing on the conflict between potential medical advancements and the moral status of the human embryo, while advocating for the protection of human dignity.
- The ethical implications of destroying embryos for research purposes.
- Comparative analysis of the therapeutic potential of adult versus embryonic stem cells.
- The regulatory landscape of SCR across different nations.

- Alternatives to destructive research, such as iPS cell technology and adult stem cell therapies.
Excerpt from the Book
The Key Problem
The embryonic stem cell research presents us with a moral problem of destruction of the embryo in the process. It brings into tension two fundamental moral principles: one principle enjoins the alleviation of suffering, and the other directs us to respect the value of human life. It is true that the harvesting and culturing of embryonic stem cells has considerable potential to bring about remarkable potential benefits in the way of alleviating debilitating medical conditions. Thus it satisfies the first principle to a very great degree. On the other hand, the harvesting of human embryonic stem cells violates the second principle in that it results in the destruction of human life with value (i.e. human embryos). Accordingly, both principles apparently cannot simultaneously be respected in the case of embryonic stem cell research. The question then is which principle ought to be given precedence in this conflict situation. Should we give more weight to the first, and permit destructive embryonic stem cell research because of its remarkable potential benefits? Or should we give more weight to the second, and prohibit destructive embryonic research because it violates respect for the value of the embryo as the very beginnings of a human life? This is the central ethical problem here.
Surplus embryos left over from in-vitro fertilization procedures in fertility clinics are thawed. The inner cell mass of an embryo is extracted. Stem cells are all that remain. The embryo is killed in the process. This raises the same ethical questions and conflicts as the ethics of abortion. Much of the controversy on stem cells has revolved around the status of the early human embryo. However, there are no major ethical concerns about the extraction of adult stem cells, from umbilical cords, skin, bone marrow, etc., as long as the donor gives permission. They are the ethically preferable avenue for research, as they are presumed to be ethically trouble free. For these obvious reasons, it has been advanced most forcefully by opponents of human embryo research.
Chapter Summary
1. What are Stem Cells?: Defines stem cells and distinguishes between the characteristics of embryonic (pluripotent) and adult (multipotent) stem cells.
1.1 What are embryonic stem cells?: Details the biological nature of embryonic stem cells and their potential to develop into various specialized cell types.
1.2 What are adult stem cells?: Explores the role of adult stem cells in tissue repair and highlights the research potential of plasticity in somatic cells.
1.3 Successes of adult vs Failures of embryonic SCRs: Contrasts the clinical risks of fetal and embryonic transplants with the promising therapeutic results achieved using adult stem cells.
2. SCR in India: The Emerging Scenario: Discusses the regulatory framework and research programs involving human embryonic stem cells within the Indian context.
3. Global Regulations on SCR: Provides an overview of how different nations regulate embryonic stem cell research, ranging from liberal to prohibitive policies.
4. The Key Problem: Examines the central ethical dilemma regarding the destruction of the embryo versus the potential for curing medical conditions.
4.1 Extracting Embryonic Stem Cells without Killing the Embryo?: Evaluates new methodologies like iPS cell technology as a way to avoid the moral dilemmas of conventional embryo research.
4.2 The Embryos in vitro: Discusses the ethical issues arising from in vitro fertilization, including the loss of fertilized ova and the status of surplus embryos.
4.3 Therapeutic Cloning: Analyses therapeutic cloning as a proposed solution to immunological incompatibility and critiques it based on the moral status of the embryo.
5. The Moral Status of the Embryo: Reviews philosophical and religious perspectives on when a human being begins to have moral status and personhood.
6. The Meaning and Significance of Human Dignity: Explores the philosophical roots of human dignity, particularly in Kantian thought and religious traditions.
7. Ethics of Healing: Argues that the medical goal of healing should not sacrifice the dignity of the human person at any stage of life.

Frequently Asked Questions
What is the primary focus of this work?
The work focuses on the ethical debate surrounding the use of human embryos in biomedical research, balancing the hope for medical progress against the protection of human life.
What are the central thematic areas?
The key themes include the biological differences between stem cell types, international regulatory variations, philosophical definitions of personhood, and the moral implications of destructive research.
What is the core research question?
The central question is whether the potential medical benefits of embryonic stem cell research justify the moral cost of destroying embryos, which are considered by many to be human life at its earliest stage.
Which scientific methods are analyzed?
The text analyzes techniques such as stem cell harvesting from blastocysts, therapeutic cloning, and the reprogramming of somatic cells into induced pluripotent stem (iPS) cells.
What topics are covered in the main section?
The main sections cover the scientific basis of stem cell research, comparative outcomes between adult and embryonic treatments, global policy regulations, and deep ethical analysis regarding human dignity.
Which keywords characterize this work?
Key terms include Stem Cell Research, Human Dignity, Bioethics, Personhood, Embryo, and Regenerative Medicine.
How does the author view the potential of adult stem cells compared to embryonic ones?
The author highlights that adult stem cells offer a promising, ethically non-controversial alternative to embryonic stem cells, often citing successful clinical breakthroughs in treating diabetes and other conditions.
What is the argument regarding human dignity in the context of therapeutic cloning?
The author argues that therapeutic cloning is unethical because it involves creating an embryo with the intent of destroying it, thereby treating a potential human life as a mere commodity or means to an end.
