Embryonic Stem Cell Therapy
Issues about the therapeutic claims on human embryonic stem cells or human ES cells are shaking the internet grounds. Currently, the preparation of human embryos implies the following steps: the production of human embryos which result from in vitro fertilization, the development of these embryos to the initial blastocyst, the isolation if the embryoblast, the culturing of cells and the recurring sub-culturing of the cells.
When it comes to therapeutic cloning, it had become known that the therapeutic use of embryonic stem cells pose considerable risks. This is so since the mice used as test subject grew tumors in them. Given these risks, there are three suggested methods suitable for therapeutic cloning.
- Replacement of the nucleus of an oocyte with the nucleus of an adult cell for a given specimen.
- Transfer of a nucleus of a cell of a specimen into an oocyte of another animal.
- Reprogramming of the nucleus of a cell of a specimen by infusing the embryonic stem cytoplast with a somatic cell karyoplast.
From researches on adult stem cells (ASC) in the last three decades, it was shown that many adult tissues have stem cells which only able to produce cells proper to a given tissue.
Given that life manufacture or fabrication can be attributed to these processes, ethical problems arising from these new technologies should first undergo a careful consideration and examination by the church and other ethics groups.
If you are interested in these kinds of treatment, it is always advisable for you to seek the attention of your immediate medical practitioner. From him, he should be able to give you the best advice. Since there are still unknown detrimental effects in embryonic stem cell therapy, it will be much safer if you let the procedure be a hundred percent certain before undergoing it.
