Cells, the smallest units of organisms, have shapes appropriate to their functions. For example, red blood cells have a concave disc shape, and the folds on the inner wall of the small intestine have an elongated cylindrical shape. How are these cell shapes determined? We have solved the mechanical laws that determine the shapes of cells by mimicking and building cells using only a few types of molecules. Such cell mimetic systems are also used in mRNA vaccines against SARS-CoV-2. In this lecture, I will discuss the mysteries of how molecules assemble to form different cell shapes.
