DNA-induced spatial entrapment of general transcription machinery can stabilize gene expression in a nondividing cell.

An important characteristic of cell differentiation is its stability. Only rarely do cells or their stem cell progenitors change their differentiation pathway. If they do, it is often accompanied by a malfunction such as cancer.

The initiation and maintenance of a differentiated state in development.

Proper function of the body is maintained by an intricate interaction and communication among cells. during the animal development how these cells are formed and maintained is an important yet elusive. Understanding of how cells such as muscle and nerve cells maintain their identities would enable us to control the diseases which include malfunctioning in cellular identities such as cancer.

Long-term association of a transcription factor with its chromatin binding site can stabilize gene expression and cell fate commitment.

Some lineage-determining transcription factors are overwhelmingly important in directing embryonic cells to a particular differentiation pathway, such as for nerve. They also have an exceptionally strong ability to force cells to change from an unrelated pathway to one preferred by their action. Transcription factors are believed to have a very short residence time of only a few seconds on their specific DNA or chromatin-binding sites.
