Adult stem cells differ from embryonic stem cells in that adult stem cells
A)can differentiate into more types of tissue.
B) are less flexible and can only change into cells similar to their source.
C) are more likely to provoke an immune response in the tissue recipient.
D) are the subject of more intense ethical debate.

Question

Adult stem cells differ from embryonic stem cells in that adult stem cells 
A)can differentiate into more types of tissue. 
B) are less flexible and can only change into cells similar to their source.​ 
C) are more likely to provoke an immune response in the tissue recipient.​ 
D) are the subject of more intense ethical debate.​

Quizplus · Accepted Answer

Adult stem cells are more restricted in their differentiation potential and can only differentiate into cell types similar to their tissue of origin. Embryonic stem cells, on the other hand, have the ability to differentiate into all cell types in the body. Therefore, choice B is correct. Choice A is incorrect because embryonic stem cells have greater differentiation potential. Choice C is incorrect because adult stem cells are less likely to provoke an immune response than embryonic stem cells, as they are less likely to be recognized as foreign. Choice D is incorrect because embryonic stem cells are the subject of more intense ethical debate due to the destruction of embryos required to obtain them.
