Pumpless platform for high-throughput dynamic multicellular culture and chemosensitivity evaluation

Area of Science:

• Biomedical Engineering
• Cell Biology
• Drug Discovery

Background:

• High-throughput screening requires robust cell culture platforms.
• Dynamic culture systems are essential for mimicking in vivo conditions.
• Evaluating drug efficacy necessitates reliable chemosensitivity assays.

Purpose of the Study:

• To develop a novel, pumpless 96-well plate platform for dynamic multicellular culture.
• To enable high-throughput chemosensitivity evaluation.
• To demonstrate the platform's ability to sustain controlled medium flow and analyze complex co-cultures.

Main Methods:

• A gravity-driven flow strategy was implemented in a 96-well plate format with 20 culture chambers.
• Computational simulation and flow visualization were used to validate medium flow dynamics.
• Osteogenic differentiation assays and high-content screening of chemosensitivity in co-cultures were performed.

Main Results:

• The platform successfully generated and sustained culture medium flow within 10% variation.
• Flow-induced shear stress effects on osteoblasts were confirmed, validating the system's biophysical simulation.
• High-throughput chemosensitivity assays on multiple myeloma and osteoblast co-cultures were efficiently conducted.

Conclusions:

• The developed platform offers a robust, pumpless solution for high-throughput dynamic multicellular culture.
• It provides a reliable tool for chemosensitivity evaluation in complex cell models.
• The system significantly streamlines experimental workflows, reducing endpoint analysis time to under 1 hour.
