| Research Abstract |
Cell differentiation is a process of stochasticity in phenotypic differentiation but shows the high homeostasis at the population level, i. e., the composition of varied differentiated cell types. A mutually inhibitory genetic circuit was designed and integrated into the E. coli genome. Also, the requirements for the amino acids(leucine and isoleucine) were introduced into the genetic circuit. The E. coli cells carrying this genetic circuit were used to mimic the cell differentiation successfully, based on the cell-to-cell communication.
