Lecture 22 : Cell growth and proliferation Flashcards
1
Q
Why do we need cell proliferation
A
- Tissue maintenance
- Replacing skin and gut cells
- Scabs
- growth repair of damaged tussye
2
Q
Stem cells
A
- Cell division occurs in proliferation zone
- Stimulated by mitogenic signals
3
Q
What is cell proliferation
A
- Cell growth + Cell division
- Vital in drug development
- Regulated to prevent cancer
4
Q
What regulates the cell cycle
A
- cyclin-dependent kinases (cdks)
- Inactive until bound to cyclin subunit
- Phosphorylate proteins that are required at certain cell cycle phases
5
Q
cell cycle essential steps
A
- very unfinished
