摘要
The invention provides a method of modulating a regulatory state of a cell. The method consists of: (a) identifying a point of interdiction within a cis regulatory network specifying a genetic regulatory architecture of a cell, and (b) introducing into a progenitor cell two or more network elements within said network to induce a predetermined series of cis regulatory network interactions resulting in a specified regulatory state of said progenitor cell. Also provided is a method of modulating a regulatory state of a cell. The method consists of: (a) identifying a point of interdiction within a cis regulatory network specifying a genetic regulatory architecture of a cellular state, and (b) introducing into a progenitor cell two or more network elements within said network to induce a predetermined series of cis regulatory network interactions resulting in a specified regulatory state of said progenitor cell. A cell having a specified regulatory state consisting of a modified genetic regulatory architecture is further provided. Methods of diagnosing and methods of treating an individual suffering from a cellular defect also are provided. The invention additionally provides a method of identifying a compound having differentiation or cell fate inducing activity.
