A.
B.
C.
D.
参考答案: B
本题详细解析:
Choice A is incorrect as although embryonic stem cells can differentiate into a large range of cell types, this is an advantage rather than a disadvantage of using them for therapeutic uses and removing adult stem cells, such as blood cell types from bone marrow, does not damage the organism that they are extracted from. Choice C is incorrect as embryonic stem cells do not have a limited capacity to differentiate, cord blood stem cells are not difficult to obtain and adult stem cells have a very low risk of being rejected by the patient. Choice D is incorrect, as there is a low risk of cord blood cells being rejected by the patient.
