Figure 4.
Fabrication of tissue spheroids by the molded microrecession method: (a) top view of the casted microrecessions before cell seeding; (b) top view of the microrecessions 1 h post-seeding, the dark areas correspond to the loose cell masses that completely fill the microrecessions; (c) top view of the recessions after 48 h incubation. Compact tissue spheroids (black spots) are evident at the center of the recession with clear demarcation from the edge of the microrecessions. Scale bar: 500 μm.
