Why stem cell research is controversial?
However, human embryonic stem cell (hESC) research is ethically and politically controversial because it involves the destruction of human embryos. In the United States, the question of when human life begins has been highly controversial and closely linked to debates over abortion. Stem cell research is legal in the United States, however, there are restrictions on its funding and use. State laws regarding research on stem cells vary widely, particularly in regard to use of embryonic stem cells. Stem cell debate in the Muslim world Some Muslims are in favour of research, arguing that the embryo does not have a soul until the later stages of its development. Others agree with the Catholic Church which says that it is immoral to destroy embryos at any stage to harvest stem cells. In 2001, President George W. Bush restricted federal funding for research on stem cells obtained from human embryos because the technology required the destruction of human life. The Catholic Church has opposed human embryonic stem cell research and any kind of human cloning because they are contrary to the dignity of procreation, of conjugal union and of human embryos. Whereas Germany, Austria, Italy, Finland, Portugal and the Netherlands prohibit or severely restrict the use of embryonic stem cells, Greece, Sweden, Spain and the United Kingdom have created the legal basis to support this research. Belgium bans reproductive cloning but allows therapeutic cloning of embryos.
Which stem cell is controversial?
Embryonic stem cells—the most controversial type—are taken from a blastocyst, an embryo at an early stage of development and comprising around 120 undifferentiated stem cells. These cells are called totipotent because they can differentiate into any cell type, including other totipotent cells. There are four main sources of stem cells, i.e. embryonic tissues, fetal tissues, adult tissues and differentiated somatic cells after they have been genetically reprogrammed, which are referred to as induced pluripotent stem cells (iPSCs). Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques. Sources of stem cells. Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques. Creation of Embryos Specifically for Research Embryos created specifically to be used in scientific research are the most problematic source of stem cells. Some religious communities believe that embryonic stem cell research destroys innocent life and should not be allowed. Others believe that while the embryo has moral worth, a group of a hundred cells no bigger than the head of a pin is not the same as a person.
When did stem cells become controversial?
But when scientists learned how to remove stem cells from human embryos in 1998, both excitement and controversy ensued. The excitement was due to the huge potential these cells have in curing human disease. The controversy centered on the moral implications of destroying human embryos. In many cases, adverse outcomes with stem cell therapy are brought about by non-homologous use of cells, Bryan noted, such as extracting stem cells from fat for injection into the eye or spinal cord. Stem cells survive much longer than ordinary cells, increasing the chance that they might accumulate genetic mutations. It might take only a few mutations for one cell to lose control over its self-renewal and growth and become the source of cancer. Catholic Church Teachings Because of this position, the Catholic Church opposes research involving human embryonic stem cells, which require the destruction of the human embryo during their isolation. In contrast, the Church has championed adult stem cell research, which does not involve human embryonic stem cells. Because of the inevitable consequences of reproductive cloning, it is prohibited in Islam. However, stem cell research for therapeutic purposes is permissible with full consideration, and all possible precautions in the pre-ensoulment stages of early fetus development, if the source is legitimate.
Why did the government ban stem cell research?
In 2001, President George W. Bush banned federal funding for embryonic stem cell research, citing that the use of these embryos, which would otherwise be discarded or would deteriorate in long-term storage, diminishes the value of human life. Stanford has been a leader in stem cell research for the past three decades. Current legal position The use of embryos for research is heavily restricted in Germany under the Embryo Protection Act (Embryonenschutzgesetz) 1991, which makes the derivation of embryonic stem cell lines a criminal offence. The embryo is also protected under the German Constitution (Grundgesetz). Currently, the only stem cell treatments approved by the Food and Drug Administration (FDA) are products that treat certain cancers and disorders of the blood and immune system. No. As per NGSR 2017, it is considered unethical and a malpractice and is violation of the existing National Guidelines for Stem Cell Research, a clinician/hospital claims to commercially offer stem cell therapy as a cure for any disease.
What is one disadvantage of stem cell research?
Cons of the stem cell therapy include: Adult stem cells are hard to grow for long period in culture. There is still no technology available to generate adult stem cells in large quantities. Stimulated pluripotent cells normally do not have any p method of maintenance and reproducibility. A path of cautious optimism While scientists have good reason to be interested in stem cells, miracle cures are not right around the corner. There are many questions about how to implement treatments to provide benefit safely. In some cases, advertised “stem cell” treatments may not actually use stem cells. Adult stem cells may not be able to be manipulated to produce all cell types, which limits how adult stem cells can be used to treat diseases. Adult stem cells are also more likely to contain abnormalities due to environmental hazards, such as toxins, or from errors acquired by the cells during replication. Many people disagree with using human embryonic cells for medical research because extracting them means destroying the embryo. This creates complex issues, as people have different beliefs about what constitutes the start of human life. Stem cell transplant has shown a 70%-80% success rate in treating non-malignant conditions such as aplastic anemia. Currently, the success rate of stem cell therapy in India is around 65%-85%. This is so as the quality of treatment and hospitality provided by India is very satisfying. The use of stem cell therapy in treating patients with autism spectrum disorder (ASD) is not recommended and its promotion and advertisement will be considered professional misconduct, the National Medical Commission (NMC) has said.
Is stem cell research legal in India?
Use of stem cells for any other purpose outside the domain of clinical trials will be considered unethical and hence is not permissible. Stem cell transplants do not lead to changes in the DNA of the donor cells. The answer is No. The Catholic Church is only against some forms of Embryonic Stem Cell Research (ESCR) that entail the destruction of human embryos. Stem cells are cells that develop very early in the human embryo after fertilization. Though Hinduism believes that life begins at conception, the religion has no official position on stem cell research.
