Research overview

This study aimed to develop a biomimetic liver-chip using co-cultured human hepatocyte (HepaRG) with hepatic stellate and endothelial cells to model NAFLD, and evaluate the therapeutic potential of scalable telomerase reverse transcriptase (hTERT)-immortalized umbilical cord mesenchymal stem cell-derived exosomes (TMSC-Exo). Effective therapeutic strategies for NAFLD remain urgently needed.

Key findings

Cells cultured in LC showed better viability compared to those in the Transwell system.

The on-chip NAFLD model mimicked the characteristics of NAFLD in vivo, including intracellular lipid accumulation and impaired hepatocyte functions in albumin synthesis, levels of urea, CYP1A2, and CYP3A4.

Both TMSC-Exo and resmetirom displayed a significant effect in reducing the lipid accumulation in the on-chip NAFLD model.

The TMSC-Exo showed superior effects in elevating the levels of albumin, urea, CYP1A2, and CYP3A4.

Study design

HepaRG cells, hepatic stellate cells, and endothelial cells were used to construct a dual-chamber biocompatible LC.

The NAFLD model was induced by free fatty acid (FFA) and applied to evaluate the efficacy of resmetirom and TMSC-Exo for the treatment of NAFLD.

Moreover, the high-fat (HF) diet-induced mouse model was analyzed to verify the in vitro results.
