Question

Which is a source of adult stem cells?

A.) bone marrow
B.) amniotic fluid
C.) embryos
D.) gametes

Answer 1

Adult stem cells have been identified in many organs and tissues, including brain, bone marrow, peripheral blood, blood vessels, skeletal muscle, skin, teeth, heart, gut, liver, ovarian epithelium, and testis. They are thought to reside in a specific area of each tissue (called a "stem cell niche").

Answer 2

The source of adult stem cell is A.) bone marrow. In mammals, stem cells can be embryonic or adult stem cells. The sources of adult stem cells are bone marrow, adipose tissue, and blood. Thanks to adult stem cells, various medical therapies are now enabled, such as transplantation of bone marrow. These cells are artificially grown and differentiated into specialised cell types.
