What are stem cells?
Undifferentiated cells that can differentiate into specialized cell types
What is regeneration?
The process of renewal, restoration, or growth that makes damaged or lost tissue functional again
What are the two main types of stem cells?
Embryonic stem cells and adult stem cells
Where are embryonic stem cells derived from?
Embryos
