Chapter 17 Cell Division and Apoptosis III
CdK activity can be suppressed by inhibitory phosphorylation
Digits in developing mouse paw are formed through apoptosis cells undergoing apoptosis
An animal cell depends on extracellular signals to survive or divide
An animal cell depends on extracellular signals to differentiate. Without extracellular signals the cell will die
Platelet derived growth factor was the first mitogen isolated stimulates cell division during wound healing
Excessive stimulation of mitogenic pathways leads to cell cycle arrest or apoptosis
Cell growth like cell division is also stimulated by extracellular signals
Many types of normal animal cells need anchorage to grow and proliferate
