Summary
This study by Napolitano, A.P., et al was published in Tissue Eng, 2007. It utilized Microtissues 3D Petri Dish® micro-molds for 3D cell culture, contributing to advances in developmental biology research.
Dynamics of the Self-Assembly of Complex Cellular Aggregates on Micromolded Nonadhesive Hydrogels
Research Overview
Self-assembly of cells into 3D structures underlies morphogenesis, and this study used rapid-prototyped micro-molded nonadhesive hydrogels to watch it happen in a low-shear environment — with simple spherical geometries and more complex ones such as toroids.
Aggregate size, shape, and composition were easily controlled, aggregates were easily retrieved, and time-lapse microscopy captured assembly dynamics directly. When normal human fibroblasts and human umbilical vein endothelial cells were seeded together, they self-segregated into multilayered spherical microtissues with a fibroblast core enveloped by endothelial cells — cell sorting reproduced in vitro.
