In this model, there is one activating protein that activates both itself and an inhibitory protein, that only inhibits the activator. By itself, transient expression of the activating protein would only produce a pattern of "both proteins off" or "spot of inhibitor on".
This section summarize some other types of patterns that we see in development: repeated patterns, like spots and stripes, as well as tissue shape and size patterning (called morphometrics). A simple ...This section summarize some other types of patterns that we see in development: repeated patterns, like spots and stripes, as well as tissue shape and size patterning (called morphometrics). A simple mathematical model will be introduced that has been used to help explain stripe and spot patterns that we see in many tissues.
