Synthetic multicellular system has always been one of the most interesting parts of syn-bio.In the fundamental researches, especially the imitations of the whole developing procedure from a single cell to a self-organized multicellular system, many pervious iGEM teams have made plenty of explorations. | Synthetic multicellular system has always been one of the most interesting parts of syn-bio.In the fundamental researches, especially the imitations of the whole developing procedure from a single cell to a self-organized multicellular system, many pervious iGEM teams have made plenty of explorations. | ||

*When cultured separately, the male/female multicellular system gets bigger and matures, and cells will differentiate into gametes,which cannot divide any more but are capable of gene transfer. | *When cultured separately, the male/female multicellular system gets bigger and matures, and cells will differentiate into gametes,which cannot divide any more but are capable of gene transfer. | ||

*After that, you mix this two liquid cultures,the male gametes will recognize the female cells and begin to transfer modified F plasmids into female gametes through sex pili. The conjugation makes female gametes return to the state of un-differentiation(called G cells),which means they can divide again but are not sexually determined. | *After that, you mix this two liquid cultures,the male gametes will recognize the female cells and begin to transfer modified F plasmids into female gametes through sex pili.

*Then,after several cell divisions,one G cell will differentiate into a G<sup>+</sup> or G<sup>-</sup>,which, like zygote , can grow into next generation of the multicellular system maybe containing genes from both male and female gametes. | *Then,after several cell divisions,one G cell will differentiate into a G<sup>+</sup> or G<sup>-</sup>,which, like zygote , can grow into next generation of the multicellular system maybe containing genes from both male and female gametes. | ||
