Stem Cell Research The following sources do not necessarily reflect the Center's position and, likewise, may or may not be consistent with a biblical worldview. These sources, however, are excellent resources for familiarizing oneself with the all sides of the issue. The Warnock Report in Debate. In this book, writers who ascribe to the Judeo-Christian philosophical and moral foundations of traditional western medical practice critically assess the way key issues were or were not addressed in Dame Mary Warnock's Report of the Committee of Inquiry into Human Fertilisation and Embryology, published by the government London, H.

Embryonic stem cell research poses a moral dilemma. It forces us to choose between two moral principles: The duty to prevent or alleviate suffering The duty to respect the value of human life In the case of embryonic stem cell research, it is impossible to respect both moral principles.

To obtain embryonic stem cells, the early embryo has to be destroyed. This means destroying a potential human life. But embryonic stem cell research could lead to the discovery of new medical treatments that would alleviate the suffering of many people. So which moral principle should have the upper hand in this situation?

The answer hinges on how we view the embryo.

Does it have the status of a person? Chapter 1 of this film introduces some of the key ethical arguments. The moral status of the embryo is a controversial and complex issue.

The main viewpoints are outlined below.

The embryo has full moral status from fertilization onwards Either the embryo is viewed as a person whilst it is still an embryo, or it is seen as a potential person. Arguments for this view Arguments against this view Development from a fertilized egg into to baby is a continuous process and any attempt to pinpoint when personhood begins is arbitrary.

A human embryo is a human being in the embryonic stage, just as an infant is a human being in the infant stage. Although an embryo does not currently have the characteristics of a person, it will become a person and should be given the respect and dignity of a person. An early embryo that has not yet been implanted into the uterus does not have the psychological, emotional or physical properties that we associate with being a person.

It therefore does not have any interests to be protected and we can use it for the benefit of patients who ARE persons.

It needs external help to develop. Even then, the probability that embryos used for in vitro fertilization will develop into full-term successful births is low. Something that could potentially become a person should not be treated as if it actually were a person.

A candidate for president is a potential president, but he or she does not have the rights of a president and should not be treated as a president.

There is a cut-off point at 14 days after fertilization Some people argue that a human embryo deserves special protection from around day 14 after fertilization because: After 14 days the embryo can no longer split to form twins. Before this point, the embryo could still be split to become two or more babies, or it might fail to develop at all.

Before day 14, the embryo has no central nervous system and therefore no senses. If we can take organs from patients who have been declared brain dead and use them for transplants, then we can also use hundred-cell embryos that have no nervous system.Embryonic stem cells hold the potential to treat a wide range of diseases.

However, the path from the lab to the clinic is a long one. Before testing those cells in a human disease, researchers must grow the right cell type, find a way to test those cells, and make sure the cells are safe in animals before moving to human trials.

What Are Embryonic Stem Cells?

Embryonic stem cells are derived from embryos at a developmental stage before the time that implantation would normally occur in the uterus. Fertilization normally occurs in the oviduct, and during the next few days, a series of cleavage divisions occur as the embryo.

A significant addition is a study published in the current Nature Neuroscience which demonstrates that mouse embryonic stem cells can restore significant function in rats with spinal cord injury. John McDonald and colleagues at Washington University in St.

Louis implanted mouse neural embryonic stem cells into experimentally produced spinal. Embryonic stem cells The term "stem cell" in Websters dictionary defines it as "An unspecialized cell that gives rise to differentiated cells", which is a fancy way of saying "stem cells can be used to copy and turn into any other type of cell".

Embryonic stem cells (ESCs) are stem cells derived from the undifferentiated inner mass cells of a human embryo. Embryonic stem cells are pluripotent, meaning they are able to grow (i.e.

Oct 01,  · Embryonic stem cells (often referred to as ES cells) are stem cells that are derived from the inner cell mass of a mammalian embryo at a very early stage of development, when it is composed of a hollow sphere of dividing cells (a blastocyst).
