| Comments |
Supporting text page S4 bottom paragraph: "The estimation of the volume and surface area of a single vesicle before and after growth from high-resolution images (not shown in figures-available upon request) provided further evidence for volume conservation and surface area increase. Before growth, the vesicle diameter measured ~3.1 µm, which corresponds to a surface area of ~30.2 µm^2 and a volume of ~15.6 µm^3. After growth, the thread-like vesicle length measured ~81.1 µm and the width measured 0.49±0.02 µm (this scale is close to the resolution limit of optical microscopy, and results in larger measurement error), which corresponds to an estimated surface area of ~124.8±5.1 µm^2 (~4-fold increase from that before growth) and an estimated volume of ~15.3±0.6 µm^3." |
