Explanation / Answer

Stem cells review questions

1. True

2. Option d - blastocyst

3. False - Human embryonic stem cells are created in vivo

4. Intestine and Bone marrow

5. False - Induced pluripotent stem cells can be created by using embryonic stem cells and adult stem cells. Not embryo

6. Option d - Both a and b

7. True

8. Legal issues: Donation of stem cells for research purpose and clinical trials with or without consent is considered as one of the major legal issues.

Social issues: Stem cells show pluripotency and they can transform into different tissues. Hence, the creation of immortal cells or tissues is considered as a major social issue in stem cell research.

Ethical issues: Stem cells such as human embryonic stem cells are considered as the beginning of life. Altering their original properties for the benefit of mankind is considered as the major ethical issue of stem cell research.
