Stem cells, present in the inner cell mass, are best described as cells that:
AHave already differentiated into a single tissue type
BAre extra-embryonic cells
CAre pluripotent and have the potency to give rise to all tissues and organs of the body
DCannot divide further
Answer & Solution
Correct answer: C. Are pluripotent and have the potency to give rise to all tissues and organs of the body
**Stem cells** within the inner cell mass are pluripotent — they retain the potency to differentiate into **all tissues and organs**. The inner cell mass also gives rise to the three germ layers (ecto/meso/endoderm).
