Chapter 5

Question 1

Symmetrical Differentiation

Answer 1

Stem cell division will result in 2 stem cell or 2 committed cells. Also known as “population asymmetry”

Question 2

Population Asymmetry

Answer 2

Stem cell division will result in 2 stem cell or 2 committed cells. Also known as “Symmetrical Differentiation”

Question 3

Asymmetry Division

Answer 3

Stem cell division will result in one stem cell and one committed cell.

Question 4

Adult Stem Cell lineage

Answer 4

Multipotent stem cell -> committed stem cell -> progenitor cell -> differentiated

Question 5

Multipotent stem cell

Answer 5

Capable of forming numerous types of cells

Question 6

Committed stem cell

Answer 6

Capable of making one or very few types of cells

Question 7

progenitor cell

Answer 7

proliferates many times but is transient in that it will become a differentiated cell eventually.

Question 8

totipotent

Answer 8

These cells are capable of producing all types of a lineage. Produce the embryo and extra embryonic tissue in mammals its the first 4-8 cells after fertilization

Question 9

pluripotent

Answer 9

The stem cells that make up the embryo

Question 10

Extra embryonic tissue

Answer 10

EX: placental, cord

Question 11

Multipotent

Answer 11

Stem cells for each specific organ. Used to regenerate cells for the organ its in.

Question 12

Hematopoietic stem cells

Answer 12

Necessary for blood formation. Multipoint system

Question 13

Stem Cell niche

Answer 13

Is a micro environment that regulates quiesents division or determination.
