参考答案: D
本题详细解析:
Choice D is correct because multipotent stem cells can produce only cells of a particular tissue or organ. Choice A is incorrect because pluripotent stem cells are usually found in early embryos and are capable of differentiating to become any cell type found in the organism except for extra-embryonic tissues such as the placenta. Additionally, they are not found in bone marrow. Choice B is incorrect because totipotent stem cells are only found in early stages of embryonic development and can produce all cell types of the organism as well as extra-embryonic tissues such as the placenta. Choice C is incorrect because stem cells are by definition, undifferentiated.
