Stem Cell Gene Network (image) Rice University Caption An overview of the stem cell gene network gives a sense of the complex process involved in cell differentiation, as transcription factors and protein complexes influence and loop back upon each other. Rice University researchers found that stem cell differentiation can be defined as a many-body problem as they developed a theoretical system to analyze large gene networks.
