Tadashi Sugawara and co-workers at The University of Tokyo, Japan, demonstrated the replication of DNA in giant vesicles using real-time PCR. The team found that the population of PCR-proceeded giant vesicles depends on vesicle size, which could have implications for the natural selection and evolution of early cells around hydrothermal vents. The team say that their findings represent a significant step forward in the attempt to construct a giant vesicles-based protocell system.
