Chapter 3 Stem cells and Regenerative Medicine

Question 1

Where are Mesenchymal stem cells commonly found

Answer 1

Bone, fat, synovium, muscle, and teeth

Question 2

What are mesenchymal cells classified as?
A. Totipotent
B. Multipotent
C. Pluripotent

Name two more types

Answer 2

B. Multipotent. So are most adult stem cells and perinatal stem cells

Question 3

What are totipotent cells?

Answer 3

Potential to differentiate into cells from each germ layer lineage (ecto, endo, and mesoderm and extraembryonic tissues like trophectoderm)

Question 4

Examples of totipotent cells

Answer 4

Fertilized zygote and very early progeny

Question 5

What are pluripotent cells

Answer 5

Ability to differentiate into cells from more than one germ layer but not extraembryonic tissues

Question 6

What are examples of pluripotent cells

Answer 6

Embryonic stem cells and induced pluripotent stem cells

Question 7

What are Multipotent cells

Answer 7

Limited to differentiation based on the germ layer it came from
