Summary
This study by Asthana, A. & Kisaalita, W. S was published in Drug Discovery Today 17, 810–817, 2012. It utilized Microtissues 3D Petri Dish® micro-molds for 3D cell culture, contributing to advances in developmental biology research.
Microtissue size and hypoxia in HTS with 3D cultures
Research Overview
Three microenvironmental factors define 3D culture: chemical composition, spatial and temporal dimensions, and physical force or substrate properties. Each has been studied individually, but their interdependence and synergistic interactions have been underappreciated.
This work makes that case by showing how microtissue size (spatial) and hypoxia (chemical) interact to determine whether a construct is physiologically relevant for cell-based high-throughput screening. It further shows how transcriptomic and proteomic results from heterogeneously sized microtissues can mislead — size control is not a detail but a prerequisite for interpretable data.
