Resource summary

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…
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…
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?
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?
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…
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?
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
