A stem cell that can give rise to all tissues except the trophoblast cells of the placenta is called

C)multipotent.
D)pluripotent.

Question

Quizplus · Accepted Answer

A pluripotent stem cell is capable of differentiating into any cell type of the embryo except for the extra-embryonic tissues such as the trophoblast cells of the placenta. Therefore, a pluripotent stem cell can give rise to all tissues of the body, but not the trophoblast cells, making it the correct answer. Totipotent stem cells are capable of giving rise to any cell type, including the extra-embryonic tissues, while multipotent stem cells are limited to differentiating into a specific subset of cell types. Retropotent is not a commonly used scientific term in stem cell biology.
