[@zebradove4186]

what do you mean by growth factor (like at 35:48 )? is it referring to ligands or cyclin?

[@sciencemusicvideos]

Growth factors are signals that induce cell division and growth. So ligands, as opposed to cyclins. Check out my tutorial about this (and all other AP Bio topics) at Learn-Biology.com.
