Summary
This study by Kabadi, P. K. et al was published in BioTechniques 59, 279–286, 2015. It utilized Microtissues 3D Petri Dish® micro-molds for 3D cell culture, contributing to advances in developmental biology research.
Into the Depths: Techniques for in Vitro Three-Dimensional Microtissue Visualization
Research Overview
3D in vitro platforms recapitulate human physiology better than 2D culture or animal models, but seeing inside them is hard — visualization and imaging remain significant practical barriers. This study optimized histology and microscopy techniques specifically for 3D microtissues.
For morphological assessment across several cell types, time points, and microtissue sizes, a two-step glycol methacrylate embedding protocol for microtissues produced in agarose hydrogels improved resolution — giving labs a concrete, validated workflow for evaluating 3D microtissue structure.
