| Research Abstract |
We have investigated vesicle deformations triggered by chemical stimuli to reveal the pathway from vesicles (molecular assemblies of lipids) to cellular life. First we established an experimental technique to examine vesicle deformation triggered by the chemical stimuli and then revealed a mechanism of a tubular membrane formation induced by pH gradient. In addition we found that chemical stimuli drive vesicles toward the chemical source, so-called chemophoresis. These observations clearly show that the chemical stimuli play important roles to develop cellular life from vesicle. In addition we succeeded to reproduce a self-production of vesicle using binary vesicles, which shed light on the pathway toward the protopcell.
