Question 1
Question
Tissue stem cells are found in our bodies. They can…

Answer
All make every type of cell in our body
Make only the cells found in their own tissues
Make embryonic stem cells
Make only red blood cells
Question 2
Question
Embryonic stem cells are ‘pluripotent’. This means they can…

Answer
Make only the types of specialized cells found in the early embryo
Make all the different types of specialized cells found in the body
Make special ‘factors’ that change all other cells into stem cells
Copy themselves
Question 3
Question
What did Shinya Yamanaka discover?

Answer
That embryonic stem cells are pluripotent
That sometimes development goes backwards in our bodies
That specialized cells can be reprogrammed to behave like tissue stem cells
That specialized cells can be reprogrammed to behave like embryonic stem cells
Question 4
Question
Reprogrammed cells are also called iPS cells. What does ‘iPS cells’ stand for?

Answer
Induced pluripotent stem cells
Induced particulate stem cells
Inductable pluripotent stem cells
Individual pluripotent stem cells
Question 5
Question
A major difference between embryonic stem cells and iPS cells is…
Image:

Answer
iPS cells can make more types of specialized cells than embryonic stem cells
iPS cells can only be made from animal cells
iPS cells can be made from an individual patient’s cells
iPS cells are found in our adult bodies
Question 6
Question
Scientists expect iPS cells to be useful for…
Image:

Answer
Studying what goes wrong in diseases
Testing drugs on human cells
Making cells to be transplanted into patients
None of the above
Question 7
Question
Can iPS cells already be used to make cells for transplantation into patients?
Image:

Answer
Yes but only for genetic diseases
No and scientists are sure they will never be used to make cells for transplants
Not yet. Scientists need to understand reprogramming better to develop therapies
Yes but only if the patient requests iPS cells
Question 8
Question
Why do some people think iPS cells might help answer some ethical questions?
Image:
0d5b590f-c76f-4e94-a7ea-4dff47980d42.JPG (image/JPG)
Answer
iPS cells can be made without destroying an embryo
iPS cells are artificial so we don’t have to worry about ethics
Shinya Yamanaka is a doctor so we can trust him
iPS cells are easy to make so it’s too late to think about ethics
Question 9
Question
iPS cells could in theory be used to make sperm and egg cells. This means…
Image:

Answer
Scientists have already made a new human being from a piece of skin
In the future, iPS cells may be useful for helping infertile couples
iPS cells can breed with each other in a dish
None of the above
Question 10
Question
What do scientists think are some important advantages of iPS cells?
Image:
8524f6b8-7977-4366-ba36-8e9f4414a694 (image/jpg)
Answer
They could be used to make cells for an individual patient that would not be rejected
They will make it easier to identify drugs that are likely to work in humans
They are very useful for studying inherited diseases
All of the above
