Author Spotlight: Automated Bioprinting for High-Throughput Vascular Model Fabrication

Developing the novel therapies targeting vascular permeability, a precursor to prevalent diseases like atherosclerosis requires rigorous preclinical testing. However, complex fabrication methods often hinder the reproducibility and high-throughput production of the in vitro models, which is a prerequisite for pharmacological testing. Here, we harness the automation of multi-material bioprinting technology to address this issue.

By integrating the conventional well plate system with computer-controlled 3D printing, we streamlined the fabrication process, simplified the culture process, and enabled the real-time analysis due to its compatibility with microplate readers and microscopic imaging setups. However, existing methods often involve multi-step and manual fabrication processes, which hinder their reproducibility. Our research introduces software-related production of in vitro human blood vessel models with complex geometries.

Bioprinting on multi-well plates allows for on-demand, high-throughput production. These advancements suggest that in vitro tissue models will be crucial for future medical discoveries.
