To understand this great complexity, a growing number of biologists and bioengineers are turning to computational models. This approach, known as systems biology, has been used successfully to model the behavior of cells grown in laboratory dishes. However, until now, no one has used it to model the behavior of cells inside a living animal.
In the March 22 online edition of the journal Science Signaling, researchers from MIT and Massachusetts General Hospital report that they have created a new computational model that describes how intestinal cells in mice respond to a natural chemical called tumor necrosis factor (TNF).
