Background:

  • High content screening (HCS) is crucial for early-stage drug discovery, enabling multiparametric cellular analysis.
  • Existing methods can be time-consuming and require significant sample volumes.

Purpose of the Study:

  • To develop an integrated microfluidic device for multiparametric HCS of human liver carcinoma (HepG2) cells.
  • To assess anti-cancer drug-induced apoptosis by measuring key cellular parameters.

Main Methods:

  • An integrated microfluidic device was designed with drug gradient generators and cell culture chambers.
  • The platform integrated liquid dilution, cell culture, stimulation, and labeling.
  • Multiparametric measurements included plasma membrane permeability, nuclear size, mitochondrial potential, and intracellular redox states.
