MPF sometimes also stands for the maturation promoting factor. Now, if the concentration levels are high enough, the cell will basically exit the G Two phase and exits the interface and enters the second stage known as the M stage. So as we'll see in the next lecture this is the stage that consists of the process of mitosis which is the process by which the cell basically divides and produces an identical daughter cell. Now, mitosis can be broken down into ProPhase, metaphase, anaphase and telephase. And the process by which the cell actually divides is known as cytokinesis. And we'll discuss that in the next lecture.
