What are the disadvantages of stem cell research?
- Limitations on ASC ability to differentiate are still uncertain; currently thought to be multi or unipotent.
- Cannot be grown for long periods of time in culture.
- Usually a very small number in each tissue making them difficult to find and purify.
Why are people against stem cell research GCSE?
While stem cell therapy has the potential to cure many diseases and injuries, there are also some risks associated with this treatment. For example, there is a risk of rejection by the body’s immune system, as well as a risk of the stem cells turning into cancer cells.
What are the religious arguments against stem cell research?
Orthodox Church in America : The American affiliation of the Orthodox Church opposes the research, stating, “The extraction of stem cells from embryos, which involves the willful taking of human life…is considered morally and ethically wrong in every instance.” The church states that it does support advances in …
What is one of the biggest challenges in stem cell research?
Manufacturing and contamination issues Ensuring manufacturing consistency throughout the whole process along with a formal safety assessment of the product are the major challenges faced in stem cell therapy.
What are 3 disadvantages of embryonic stem cells?
| Stem cell type | Limitations | Advantages |
|---|---|---|
| Embryonic stem cells | (1) Ethical dilemmas (2) Possible immune rejection after implantation (3) Only a small number of differentiated cardiomyoctes can be generated (4) May lead to teratocarcinomas (5) Genetic instability | Can differentiate into cells of all three germ layers |
Why are some people opposed to stem cell research and why do others believe it is unethical to not pursue such research?
The main objections are based on people’s cultural and religious beliefs. Catholics and some conservative Protestants, for example, oppose stem-cell research because they believe that human life starts at conception, making it unethical to destroy a zygote or an embryo, or even a blastocyst.
What are 3 arguments for stem cell research?
Pros. Embryonic stem cells are thought by most scientists and researchers to hold potential cures for spinal cord injuries, multiple sclerosis, diabetes, Parkinson’s disease, cancer, Alzheimer’s disease, heart disease, hundreds of rare immune system and genetic disorders and much more.
What are some of the arguments about using stem cells?
- Stem cell technologies would be very expensive and available only to rich countries and to rich people.
- Stem cell research would deviate efforts from other health strategies.
- Interference with the genome involves ‘playing God’
- Somatic cell nuclear transfer is immoral as it involves creating embryos only to destroy them.
Do you agree that stem cell research is like scientists playing God?
In all, however, I would conclude that stem cells have benefits that outweigh the risks, and have faith in the medical community for upholding bioethical standards today: they have, and likely will, continue ensuring that we do not “play God” with the powers of stem cell research.
What are the ethical disadvantages of stem cell therapy?
The use of donated embryos to produce ES cells If the embryo is so considered, then it will be morally impermissible to use it merely as a means to an end, rather than as an end in itself. This would preclude both embryo research and any other procedure not directed to the benefit of that actual embryo.
What are three sources of stem cells and the advantages and disadvantages?
| Stem cell type | Sources | Disadvantages |
|---|---|---|
| Placenta-derived stem cells | Cells from the placenta of newborns | Low frequency (but higher than cord blood) |
| Adult stem cells | Cells from adult tissues | Very low frequency |
| Induced pluripotent stem (iPS) cells | Cells from adult tissues reprogramed to pluripotency | Not patentable |
