#1
Front (Question)
What are the two defining features of stem cells?
Back (Answer)
Self-renewal and potency.
#2
Front (Question)
What is totipotency?
Back (Answer)
The ability to differentiate into all cell types, including extra-embryonic tissues. Example: zygote.
#3
Front (Question)
What is pluripotency?
Back (Answer)
The ability to differentiate into almost all body cells, but not extra-embryonic tissues. Example: embryonic stem cells.
#4
Front (Question)
What is multipotency?
Back (Answer)
The ability to differentiate into a limited number of cell types related to tissue origin. Example: bone marrow stem cells.
#5
Front (Question)
How do gradients affect gene expression in embryonic stem cells?
Back (Answer)
Morphogen concentration gradients provide positional information, guiding differentiation.
