Cell growth• Growth factors– PDGF=Platelet-derived growth factor

Preventative Measures

• Separation is very careful

• Density-dependent inhibition

• Anchorage dependence

• Apoptosis

Page 4: What controls the cell cycle?  What happens if a cell doesn’t pass a checkpoint?

Cancer

• No growth factor needed

• Can be immortal if nutrients available
