Question

question 3 (1 point)
the most medically useful stem cells are .... and come from ....

a multipotent stem cells; adult tissues

b somatic stem cells; embryonic tissues

c pluripotent stem cells; adult tissues

d pluripotent stem cells; embryonic tissues

Explanation:

To solve this, we analyze each option:

• Option a: Multipotent stem cells can differentiate into a limited number of cell types (from adult tissues), but they are less versatile than pluripotent ones for broad medical use.
• Option b: Somatic stem cells (another term for adult stem cells) come from adult tissues, not embryonic, so this is incorrect.
• Option c: Pluripotent stem cells do not come from adult tissues (adult tissues have mostly multipotent or unipotent stem cells), so this is wrong.
• Option d: Pluripotent stem cells can differentiate into almost all cell types in the body and are derived from embryonic tissues, making them highly useful for medical applications like regenerative medicine.

Answer:

d. pluripotent stem cells; embryonic tissues
