How does the view of modern media and literature vary to the biblical literature on the medical developments of Cloning?

This essay deals with the issues raised in the media by the rapid technological developments of cloning and in particular on the religious beliefs of the uniqueness of life. It will also touch upon the ethical and legal issues brought about through out the development of cloning.

A clone is a group of genetically identical organisms. Identical twins are therefore a clone since both come form one fertilised egg that is divided into two genetically identical cells that then separate.

In the process of mammalian cloning there are two processes. Nuclear Transfer is where the nucleus is removed from the unfertilised egg cell; this eliminates all its genetic information. The cell nucleus of the individual being cloned is introduced into the enucleated egg cell though cell fusion. If this is done in the right conditions, the egg cell then begins to divide and go through a process of foetal developments as if it had been fertilised normally.

The other process is artificial twinning which is a process of splitting the embryo into two or more embryos. First an egg cell is fertilised by sperm, then left to grow into an embryo. The embryo is split into two or more embryos when it is still in the early stage of development. The split embryo are nurtured into new embryos, all genetically identical, then implanted into the surrogate mother to grow. This is not the same as nuclear transfer as the born animal has biological parents and is a clone of its brothers and sisters.

Cloning of mammals has proven to be difficult and has only developed in the past few years through a long line of research.

In 1997 came the most famous sheep of all Dolly who was cloned using a cell from an adult sheep. She represented a new departure because she was the first mammal to have been cloned using a nucleus taken from an adult sheep. She possessed a genetic code identical to that of her original parents. This breakthrough raised the possibility of cloning adult mammals rather than embryos.

However it is not known yet whether nuclear transfer will be possible in the process of cloning humans.

Most future cloning developments will not even concern the reproduction of humans but it will focus on using cloning to understand cell development, heredity and genetic structure. For example cloning research may contribute to disease treatment by allowing scientists to reprogram cells. Through research, skin cells could be reprogrammed into insulin producing cells in the pancreas. These skin cells would then be introduced into the pancreas of the diabetes patients, allowing them to produce insulin. However a number of other applications has been envisaged. It could be used in future research in which cloning may be beneficial, such as encouraging research into cloned tissues to work with the basic building blocks of life ‘the stem cells’ and discovering how to reprogramme them in such away that they will develop into the tissue that is needed such as skin or heart muscle or nerve cells. These stem cells can be acquired from the foetus which has miscarried or been aborted. In order to obtain these stem cells which are genetically identical to the suffer, it is necessary to use the cloning technique, taking the nucleus of a cell from the affected person and putting it into a human egg, from which the nucleus has been removed. This is the creation of life; it is genetically identical to the person who is suffering. After just a few days of cell division, the stem cells would be removed from the embryo and then the embryo would be destroyed, this would give you a cell line which would never be human but would be used for producing identical tissue for a patient who needs a supply of cells or tissue for grafting, such as replacing heart muscle tissue which would offer hope for people with heart disease, or brain tissue which would help suffers of Alzheimer’s.

However many of these future applications of cloning involve the creation of embryo solely as a source of cells and destroying them.

In an article by Roger Highfield science editor of The Daily Telegraph raises the ethical question, does the 100 cell early embryo that will be used in the stem cell research count as a person? That is the question at the heart of the debate. At one extreme, pro-life groups, the Catholic Church and some other religious organisations argue that the embryo becomes a human being as soon as an egg is fertilised, and should be accorded the ...
