1
Q
What is a Stem Cell
A
- Primitive cell that can either self-renew (reproduce itself) or give rise ot more specialized cell types
2
Q
Totipotency
A
- Ability of a cell to give rise to all cells of an organism, including embryonic and extraembryonic tissues (cells which support embryonic development) Ex. Zygote
3
Q
Pluripotency
A
Ability of a cell to give rise to all cells of the embryo and subsequently adult tissues ex. embryonic stem cells
4
Q
Multipotency
A
Ability of a cell to give rise ot different cell types of a given lineage (ex. adult stem cells)
