Area of Science:

  • Cancer Biology
  • Biomedical Engineering
  • Pharmacology

Background:

  • Three-dimensional (3D) spheroid cell cultures are valuable models in cancer research and drug screening.
  • Mimicking lung cancer pathology requires advanced in vitro models.

Purpose of the Study:

  • To develop a lung carcinoma spheroid-based microfluidic platform with perfusion.
  • To investigate the anti-cancer effects of panaxatriol using this platform.

Main Methods:

  • Formation of lung carcinoma spheroids using agar microtissue molds.
  • Culturing spheroids in a 3D dynamic microfluidic system with perfusion.
  • Assessing spheroid size, fragmentation, and cell viability after drug treatment.

Main Results:

  • Panaxatriol reduced spheroid size and induced fragmentation.
  • Panaxatriol demonstrated significant cytotoxicity to cancer cells (IC50 = 61.55 µM).
  • Drug efficacy was higher in dynamic microfluidic systems compared to static conditions.

Conclusions:

  • The developed microfluidic platform effectively models lung cancer pathology and drug response.
  • Panaxatriol shows potential as an anti-cancer therapeutic, particularly in dynamic flow conditions.
  • This platform can improve drug screening accuracy and accelerate therapeutic translation.
