Supporting stem cells without destroying embryos

Using embryonic stem cells effectively

Utter the word the foetus and a heated discussion will follow. It is in particular the case in the field of the embryonic search for stem cells.

Embryonic stem cells are received from foetus-research in the therapeutic properties of these stem cells and have started the massive discussion among politicians, religious groups, and the general public and to finish, a minority of scientists.


Pros and cons of the discussion of stem cells

The adversaries of the embryonic search for stem cells compare the destruction of an embryo with an abortion. They suppose that the embryo constitutes the life because it has the prospective to grow entirely into a human being. Those against the embryonic use of stem cells believe that it is immoral and non conformist to annihilate one life to save others.

By employing stem cells and by throwing the embryo, one thinks that the human life is finally devalued by this act and making a slippery way for other scientific procedures which also do not value life. In particular, much of religious groups which are resolutely anti-abortions damned the embryonic search for stem cells and all its submissions. Other arguments against the embryonic cells of stem quote the fact that the adult stem cells are those which are being currently employed in the therapies and thus there is no necessity to enter the world of embryonic stem cells.

Those which support the embryonic search for stem cells believe that an embryo is not equivalent to the human life because it is inside the uterus. The defenders also affirm that the social costs of much of diseases and conditions, in financial and misery aspects, means that the moral concern concerning the embryonic use of stem cells is not adequate to validate the discontinuance of this talented therapy.

An additional disagreement for the embryonic search for stem cells is that the embryos are surplus of in vitro fertilization and would be differently destroyed, thus they would have the place of being put at a greater use. Apart form this, the belief is that the embryos that were of the legal abortions, which were already destroyed, would better be employed as a progress of the health of the people rather than been discarded.

Are there any solutions to this enigma?

Fortunately, there are substitutes but they are not perfect and they require more research before they can be employed with an acceptable level of success. Two new embryonic treatments of stem cells avoid the foetal destruction by one or the other:

 * Deriving the embryonic cells of stem without destroying the foetus

 * Obtaining the embryonic cells of stem without really generating a foetus

In the altered nuclear transfer (ANT), an embryo is not produced. An unoriginal part of the nuclear transfer of somatic cells (SCNT), the core of the somatic cell (any cell of body other than egg) is distorted, or genetically reprogrammed, before being transferred to the egg. The outcome of change is that the DNA of somatic cells always generates stem cells but does not produce an embryo.

In the removal of blastomere, an embryo is produced but is not destroyed. This process is carried out on a two day old embryo, according to the separation of egg fertilized in eight blastomeres or cells. Previously, techniques used to harvest implying the derivation of the embryonic cells of stem to a later stage development, when the embryo is composed of roughly 150 cells. When these cells were harvested, the embryo was ruined. Embryonic stem cells can in place be extracted starting from the blastomeres, therefore preventing the destruction of embryo and allowing the use of the stem cells for the research and the therapeutic treatment of the disease.

The other option is to employ the adult stem cells strictly because those are derived from adult tissues. The therapeutic potential is lesser, however, because the adult stem cells do not discriminate in as many various types of cells just as the embryonic stem cells would be able to do. They are also required to have developed genetic anomalies with time and they do not tend to fold up as successfully.

It is not very probable that a total solution will be found for the embryonic discussion of stem cells any time soon. While waiting for it to happen, the national and international policies with collective public sights will probably direct the research efforts and of therapy for the embryonic stem cells. There is no doubt that the stem cells have the great prospective for the treatment of the disease but unfortunately, there is an element of doubt regarding the implication of morals to persist this prospective.
