Outline of Final Research Achievements

In this study, we aimed to establish fundamental technologies for realizing reconstruction of living cells from biomolecules. Through this study, we found the condition for emergence of a bacterial protein localization wave, which determines the cell division plane, in fully confined lipid spaces. We also developed a novel fusion method for artificial cells to introduce a large variety of membrane proteins to lipid membrane on artificial cells as well as living cells. Furthermore, we established an in vitro transcription-translation system for genomic DNA, and successfully detected mRNA transcribed from genome in artificial cells. The findings and methods developed in this study are expected to be an important platform for creating artificial cells behaving like living cells.
