Question #2
Embryonic stem cells are 'pluripotent'.  This means they can ...

B.   make all the different types of specialized cells found in the body
C.   copy themselves
D.   make only the types of specialized cells found in the early embryo.

B.   FALSE
Question #4
What did Shinya Yamanaka discover?
A.   That embryonic stem cells are pluripotent
B.   That sometimes development goes backwards in our bodies
C.   That specialized cells can be reprogrammed to behave like embryonic stem cells
Question #5
Reprogrammed cells are also called iPS cells.  What does 'iPS' stand for?
A.   Induced pluripotent stem
B.   Individual pluripotent stem
C.   Induced particulate stem
D.   Inductable pluripotent stem
Question #6
Why do some people think iPS cells might help answer solve some ethical questions surrounding stem cell research?
A.   iPS cells are artificial so we don't have to worry about ethics.
B.   iPS cells are easy to make so it's too late to think about ethics
C.   Shinya Yamanaka is a doctor so we can trust him
D.   iPS cells can be made without destroying an embryo.

A major difference between embryonic stem cells and iPS cells is...
A.   iPS cells can only be made from plant cells
B.   iPS cells are found in our adult bodies
C.   iPS cells can make more types of specialized cells than embryonic stem cells
D.   iPS cells can be made from an individual patient's cells and will be genetically identical to that patient
Question #8
Can iPS be used at this time to make cells for transplantation into patients?
A.   NO
B.   YES
