Scientists Create Functional Blood Vessels and Liver Lobules on Microfluidic Chips

Laser-patterned microvascular networks in hydrogels are now modeling inflammation-induced leakiness together with liver lobule function on microphysiological platforms.

Overview

  • Researchers at Texas A&M engineered customizable vessel-chips that replicate aneurysms, stenosis and branching to study blood flow and vascular disease mechanisms with human endothelial cells.
  • TU Wien researchers applied ultrashort femtosecond laser pulses to pattern precise, reproducible microvascular networks in hydrogels that maintain perfusion and structural integrity under cell remodeling.
  • Artificial vessels on these chips respond to inflammatory signals by increasing permeability, closely mimicking natural endothelial behavior.
  • In collaboration with Keio University, teams vascularized liver lobule models on the platforms, replicating central vein and sinusoid architecture to enhance metabolic activity.
  • These organ-on-a-chip advancements pave the way for integrating personalized, non-animal microphysiological models into preclinical drug screening pipelines.
