Tissue stem cells are found in our bodies. They can…
Antworten
-
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
Frage 2
Frage
Embryonic stem cells are ‘pluripotent’. This means they can…
Antworten
-
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
Frage 3
Frage
What did Shinya Yamanaka discover?
Antworten
-
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
Frage 4
Frage
Reprogrammed cells are also called iPS cells. What does ‘iPS cells’ stand for?
Antworten
-
Induced pluripotent stem cells
-
Induced particulate stem cells
-
Inductable pluripotent stem cells
-
Individual pluripotent stem cells
Frage 5
Frage
A major difference between embryonic stem cells and iPS cells is…
Antworten
-
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
Frage 6
Frage
Scientists expect iPS cells to be useful for…
Antworten
-
Studying what goes wrong in diseases
-
Testing drugs on human cells
-
Making cells to be transplanted into patients
-
None of the above
Frage 7
Frage
Can iPS cells already be used to make cells for transplantation into patients?
Antworten
-
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
Frage 8
Frage
Why do some people think iPS cells might help answer some ethical questions?
Antworten
-
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
Frage 9
Frage
iPS cells could in theory be used to make sperm and egg cells. This means…
Antworten
-
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
Frage 10
Frage
What do scientists think are some important advantages of iPS cells?
Antworten
-
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
