what are two major concerns for using stem cells reproductively?
Using stem cells for reproduction involves a lot of ethical concerns such as-
1. Consent from gamete donor- This issue arises from the fact that gamete or sperm or oocyte donors are used to create frozen embryo who do not participate any further in assisted reproduction or childrearing. Sometimes gamete(sperm) donors who are willing to help women and couples bear children may object to the use of their genetic materials for embryonic research. Thus there should be a specific consent for stem cell research from both embryo and gamete donors.
2. Confidentiality- Without confidentiality, major issues can arise such as unwanted publicity or even harassment by opponents of embryonic human stem cell research. For this, the computer storing these data should not be connected to the Internet.
Sometimes payment option for the donors also serve as a major ethical issue, For example, it is said that it may induce women to undertake excessive risks, particularly poorly educated women who have limited options for employment,
What are the mechanisms of action in stem cells? What effects does stem cells have in the body? What are potential uses of these stem cell compounds? Should stem cells be prescribed/used by Doctors? How is the safety of these molecules?
Question 3 What is the purpose of Stem Cell Therapy? Use of stem cells to prevent an animal from aging once it reaches maturity Use of stem cells to create an embryo (without using a fertilized egg) Use of stem cells to create a new individual (for example the sheep Dolly) Use of stem cells to fix or replace tissues that have been damaged Use of stem cells to change one type of tissue into another (for example, muscle tissue...
How can stem cells replace faulty cells in the body? Multiple Choice Stem cells can be coaxed to differentiate into the needed specific cell type. Stem cells can mitotically divide, providing more stem cells to directly replace the faulty cells and their functions. Stem cells can meiotically divide, providing more stem cells to directly replace the faulty cells and their functions. Faulty cells can be coaxed to differentiate into stem cells and directly replace the faulty cells and their functions....
1. What is a stem cell line? A. Stem Cells lined up in a row. B. Stem Cells in the lineage. C. A population of Stem Cells grown by scientists. D. A Stem Cell broken down, with it's contents placed in a line. 2. What is an Adult Stem Cell? A. A cell extracted from mature tissue. B. A cell extracted only from children. C. A cell extracted only from adults. D. Both A and C. E. None of the...
The difference between embryonic and adult stem cells is that a.Embryonic stem cells are normally present during development, adult stem cells are only present when gene therapy is used to induce them to form. b.Both adult stem cells and embryonic stem cells can be treated with growth factors to become any tissue type in the body. c.None of the above. d. Embryonic stem cells are pluripotent, adult stem cells might be pluripotent OR multipotent. e.Adult stem cells are multipotent, embryonic...
What is fundamentally important about the difference between using embryonic or adult stem cells in scientific research?
7. Which of the following are potential barriers to stem cell therapy? a) Injection of cells may cause either inflammation or be rejected by recipient. b) For iPSC, retroviral insertion of transgenes for reprogramming can cause deleterious mutation. c) Not all stem cells in the population may differentiate into the appropriate tissue and due to the self renewal property, could lead to cancer d) There are societal ethical concerns over the source of embryonic stem cells.
What are stem cells and what do you think about the ethics of stem cell research? What do you think are some potential benefits or problems resulting from this research and development?
The source of red and white blood cells are undifferentiated cells called stem cells. Currently , a great controversy exists over the source and use of these cells for research and medical purposes. What is the nature of the controversy? What kinds of abnormalities are associated with stem cells ? To what medical purposes might these cells be used?
What ethical issues are involved in stem cell research and human cloning? Are there any concerns that are outweighed by potential benefits? Explain.
