Every year millions of people are killed by illness or accident; nightly news is full of reports of the devastating effects of cancer, fears and disasters that may distort and paralyze people. Embryonic stem cell research is part of biomedical science, it reduces patient pain by treating diseases and defects, makes organs and tissues for patients requiring transplantation or skin transplantation, and spinal cord injury Regenerate axons and create new treatments. , Medicine and immunization. However, the US government does not support this research, which has certain influence on medicine; only a few stem cell lines are licensed and there are few federal funds. ... more content
Human embryonic stem cells (hESCs) are pluripotent and are obtained from the internal mass of 4-5 day old human blastocysts consisting of about 100 cells ("Stem Cell Research", 2009).
Stem cells grow in a laboratory petri dish and are not transplanted into a woman's uterus. These cells can be used to produce stem cell lines that can grow indefinitely under optimal conditions ("Stem Cells and Diseases", 2011). Embryonic stem cells can be derived from existing stem cell lines (any cell group from the same original embryo), abortive or abortive embryos, unused in vitro fertilized embryos, and clonal embryos produced from somatic cell nuclear transfer (from unfertilized) . Although the egg is replaced by the nucleus of the adult stem cell, this technique is used for therapeutic cloning, which will be the patient's growth organs and skin grafts, but prior to 2001, the federal government's financial aid Only research was done. Some of the embryonic stem cell lines created by the embryos used (Dunn, 2005; Embryo and Fetal Research, 2008, Therapeutic Cloning, 2009) These strains allow scientists to fully exploit and make use of potential discoveries It is not enough to do.
If the government's support is limited, political and religious controversy may intensify and this controversy has disappeared.
Despite the scientific progress made it possible to completely avoid the ethical controversy surrounding research on embryonic stem cells and ethical controversy, the US government started providing federal funds for embryonic stem cell research in 2001 did. Until now, the Federal Fund could not be used for embryonic stem cell research, but his policy allowed the government to fund the study of a limited number of embryonic stem cell lines . The statements describing these restrictions are as follows.
Support the use of embryonic stem cells for research. It is necessary (and ethically) that the government funds research on embryonic stem cells, which help scientists find therapeutic methods and treatments for diseases. Embryos are not human beings. Small blastocysts (embryos used for embryonic stem cell research) have no human characteristics. Testing embryonic / embryonic stem cells is not murder. Embryonic stem cells may treat chronic and degenerative diseases and current medications can not be effectively treated. Embryonic stem cells have been shown to be effective in treating cardiac disorders in mice
Embryonic stem cells and adult stem cells are often compared in the field of stem cell research. The use of controversial embryonic stem cells is supported on the basis of their many advantages over adult stem cells. Embryonic stem cells are more readily available; they have greater cell proliferation, also known as proliferation, ability; and they are more versatile. Blastocyst stem cells are isolated from the embryo during the blastocyst stage and the process destroys the structure of the embryo to the extent that the embryo can no longer grow. Since these stem cells are obtained when the inner cell mass is concentrated in the embryo, they are more readily available than adult stem cells and the number of adult stem cells is limited. Another beneficial advantage of embryonic stem cells is their ability to grow and grow indefinitely when cultured under appropriate conditions (Devolder 9)
