What are two ethical issues with using stem cells?
|Phase of research||Ethical issues|
|1. Payment to oocyte donors|
|2. Medical risks of oocyte retrieval|

What are the risks or side effects with regenerative therapy?
Side effects have different levels of severity, especially when it comes to stem cell treatment. Most of the procedure’s risks result in short-term side effects such as infection, bleeding, and pain from tissue or nerve inflammation.
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 pros and cons 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|
What is stem cell research and why is it controversial?
The stem cell controversy is the consideration of the ethics of research involving the development and use of human embryos. Most commonly, this controversy focuses on embryonic stem cells. Not all stem cell research involves human embryos.
Why does insurance not cover stem cells?
Insurance policies will not cover treatments they consider experimental. By experimental, they mean procedures or treatments that raise concerns over harmful effects and/or unproven benefits. Insurance companies consider most instances of stem cell therapy to be experimental and will not cover the costs.
Is stem cell therapy FDA approved?
Currently, the only stem cell products that are FDA-approved for use in the United States consist of blood-forming stem cells (also known as hematopoietic progenitor cells) that are derived from umbilical cord blood.
Why are stem cells controversial?
