Stem Cell Quiz

1. A stem cell is a cell that can continue to grow and make more of itself and, if given the correct signal, it can become a particular specialized cell such as a red blood cell or a neuron. There are two types of stem cells: adult stem cells and embryonic stem cells. True or False?
         False.
         True.

2. Adult stem cells can be found in…
         A: Bone marrow
         B: Skin cells.
         C: Umbilical cord blood.
         D: Just about any part of the body.
         E: All of the above.

3. Human embryonic stem cells are only obtained by killing human embryos.
         A: True.
         B: False.

4. No one has to die to retrieve adult stem cells.
         A: True.
         B: False.

5. Remaining human embryos from infertility treatments should be donated for embryonic stem cell research because they would be discarded anyway.
         A: True.
         B: False.

6. How many diseases and conditions have been successfully treated using adult stem cells?
         A: Zero
         B: 12
         C: 73
         D: None of the above.

7. How many diseases and conditions have been successfully treated using human embryonic stem cells?
         A: Zero
         B: 12
         C: 73
         D: None of the above.

8. Embryonic stem cells are too dangerous to put into a person’s body because…
         A: The implanted embryonic stem cells will be rejected by the person’s immune system because they are foreign tissue.
         B: Embryonic stem cells grow uncontrollably and might form a tumor.
         C: It is extremely difficult to get embryonic stem cells to form just one particular cell type such as a neuron. They usually form a mixture of several cell types such as bone or hair which continue to grow.
         D: All of the above.
