Area of Science:

  • * Hepatology and Drug Development
  • * Microphysiological Systems (MPS)
  • * In Vitro Liver Modeling

Background:

  • * Microphysiological systems (MPS) advance in vitro liver modeling for drug testing and disease studies.
  • * A key challenge is balancing high-throughput screening with complex biological data.
  • * Existing liver MPS require optimization for increased experimental capacity.

Purpose of the Study:

  • * To develop a scalable, higher-throughput version of the liver acinus microphysiological system (LAMPS).
  • * To maintain the high-content biological complexity of the original LAMPS.
  • * To enable enhanced drug efficacy, metabolism, toxicity (ADME-Tox) testing, and disease modeling.

Main Methods:

  • * Development of a seven-chamber microfluidic design for the higher-throughput LAMPS (ht-LAMPS).
  • * Utilized four key liver cell types: primary hepatocytes, LSECs, Kupffer-like cells (THP-1), and hepatic stellate cells (LX-2).
  • * Validated recapitulation of oxygen zonation-dependent liver phenotypes and MASLD progression markers.

Main Results:

  • * The ht-LAMPS successfully recapitulated key physiological liver phenotypes, including viability, marker secretion, mitochondrial activity, and lipid accumulation.
  • * Demonstrated reproducibility of liver function and disease modeling in the higher-throughput format.
  • * The model effectively replicated metabolic dysfunction-associated steatotic liver disease (MASLD) phenotypes, such as steatosis and inflammatory/profibrotic markers.

Conclusions:

  • * The ht-LAMPS offers a scalable solution for liver research, increasing throughput without compromising biological fidelity.
  • * This advanced platform supports robust in vitro modeling of liver function and disease progression.
  • * ht-LAMPS is suitable for drug discovery and ADME-Tox testing in MASLD and other liver conditions.
