Summary
This study by Ip, B. C. et al was published in 2018. It utilized Microtissues 3D Petri Dish® micro-molds for 3D cell culture, contributing to advances in developmental biology research.
Perfused Organ Cell‐Dense Macrotissues Assembled from Prefabricated Living Microtissues
Research Overview
Engineered tissues usually fall short of physiological cell density and size because diffusion alone cannot feed a large construct. This study reported the Bio-Pick, Place, and Perfuse (Bio-P3) — an integrated biofabrication-bioreactor platform that semi-automatically and rapidly assembles cell-dense macrotissues containing 100 million cells while actively perfusing them.
The system grips, aligns, and stacks prefabricated, scaffold-free microtissue parts with integrated lumens onto a perfusable build platform, so nutrient exchange continues during assembly — a route past the diffusion limit that has constrained tissue engineering.
