Figure 1: Scanning electron microscopy images of 300-micron-diameter multicellular aggregates of (A) human umbilical smooth muscle cells, and (B) N-cadherin transfected Chinese hamster ovary cells. The aggregate with larger surface tension (A) displays a smooth surface, while the one with smaller surface tension (B) has a berrylike surface.
