Why is STEM research bad?
Why is STEM research bad?
Stem cells differentiate into many specialized cells and are therefore of interest in chronic conditions for which treatment is limited. However, human embryonic stem cell (HESC) research is unethical since it results in the destruction of human life for research purposes.
What are the risks and challenges of gene therapy and stem cell research?
Gene therapy has some potential risks. A gene can’t easily be inserted directly into your cells….Risks
- Unwanted immune system reaction. Your body’s immune system may see the newly introduced viruses as intruders and attack them.
- Targeting the wrong cells.
- Infection caused by the virus.
- Possibility of causing a tumor.
What are the disadvantages of the use of stem cells in medicine?
The main disadvantage of stem cell research has to do with the way that they’re acquired-that is, it involves the destruction of human embryos. Last but not least, transplanted stem cells can have high rejection rates. After all, they’re derived from foreign embryos.
Why is stem cell research banned in the US?
Stem cell research is legal in the United States, however, there are restrictions on its funding and use. When stem cells are obtained from living human embryos, the harvesting of these cells necessitates destruction of the embryos, which is controversial in the U.S.
What are the limitations of stem cell therapy?
Even though cells have the chemical capacity to detect damaged tissue, there might be a physical obstruction (like a blocked artery) that will not allow these stem cells to “travel” to damaged areas. If the cause of the obstruction is not eradicated, there will be poor, slow, or no tissue regeneration.
What are advantages and disadvantages of stem cells?
Table 1
| 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 |
