What are the advantages of using stem cells for research GCSE?
What are the advantages of using stem cells for research GCSE?
Stem cells can divide to produce new cells, which can then divide into different cell types. They therefore have the potential to be transplanted into patients to treat medical conditions and disease. They could be used to replace cells that have been damaged or destroyed, for example: in type 1 diabetes.
What are the advantages and disadvantages of using stem cells for research?
Stem cells have great potential, in treating patients with currently untreatable conditions, growing organs for transplants and research. But there are clinical, ethical and social issues with their use. These issues will be different for growth and transplant of adult , embryonic and therapeutically-cloned stem cells.
What are the cons 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.
What are the advantages of stem cell research?
Researchers hope stem cell studies can help to:
- Increase understanding of how diseases occur.
- Generate healthy cells to replace cells affected by disease (regenerative medicine).
- Test new drugs for safety and effectiveness.
What are the disadvantages of stem cells BBC Bitesize?
Mutations have been observed in stem cells cultured for a number of generations, and some mutated stem cells have been observed to behave like cancer cells. Cultured stem cells could be contaminated with viruses which would be transferred to a patient.
What are the advantages and disadvantages of the different type 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 |
What are the risks and challenges of stem cell research?
The risks to research participants undergoing stem cell transplantation include tumour formation, inappropriate stem cell migration, immune rejection of transplanted stem cells, haemorrhage during neurosurgery and postoperative infection.
What are the pros and cons of embryonic stem cells?
What are stem cells GCSE AQA?
Stem cells are cells that have not undergone differentiation . A cell which has not yet become specialised is called undifferentiated.
Why is stem cell research bad?
Some opponents of stem cell research argue that it offends human dignity or harms or destroys human life. Proponents argue that easing suffering and disease promotes human dignity and happiness, and that destroying a blastocyst is not the same as taking a human life.
What are the negative effects of stem cells?
