I will present a model system of self-reproducing vesicles that I worked with during my stay in the lab of Prof. Imai in Tohoku University, Japan. Sakuma and Imai found a simple binary vesicle capable of self-reproduction utilizing cycling temperatures in a range of 30-50°C and a pH of around 7 [1]. The division is recursive and robust. Shape deformations of this model vesicle throughout a division cycle [2], a theory of vesicle division [3] as well as recent experimental results and possible applications will be discussed.
