Please help!! which are sources of adult stem cells? select 3 options.

a. bone marrow
b. amniotic fluid
c. brain
d. gametes
e. liver
f. embryo

Bone marrow, amniotic fluid, and brain

Explanation:

In the choices, I notice that liver is also a part of Adult stem cells but so are the ones I mentioned.

Adult stem cells are found in small numbers in most adult tissues. To not get confused by embryonic stem cell, adult stem cells are there to replace dead cells throughout the growing process of a human which is also called somatic stem cells but this type of cells helps with the brain, bone and fluid

Hope this helped :)
