Many Paths to the Same Attractor State

Caption: When exposed to a growth factor, a blood stem cell, represented by a blue marble, falls into a new "attractor state," depicted as a valley in a landscape, to become a red blood cell. Different influences, such as differentiation factors, can lead stem cells to the same attractor state, but each cell can take very different paths though the landscape to get there (just as a marble might take a different path each time it rolls down a hill).
