Introduction
Reproducing the tumor microenvironment in vitro requires more than conventional 3D culture systems. Physiological relevance depends on the integration of structural complexity with dynamic mechanical cues such as fluid flow and biomechanical stimulation.
In this context, a joint study with PromoCell® was conducted to develop an esophageal adenocarcinoma-on-chip model based on the MIVO® cancer-on-chip platform, combining advanced 3D tumor spheroids with controlled dynamic perfusion.
A cancer-on-chip model integrating 3D culture and dynamic flow
The experimental setup integrates two key components:
- 3D tumor spheroids generated using a chemically defined, serum-free 3D Tumorsphere Medium XF
- Controlled dynamic perfusion within the MIVO® platform, enabling continuous fluid flow and biomechanical stimulation
This integrated cancer-on-chip system allows the reproduction of more physiologically relevant tumor microenvironment conditions compared to static culture systems.
Investigating the tumor microenvironment under physiological conditions
The model enables the analysis of how dynamic flow and mechanical forces influence:
- Tumor spheroid growth and expansion
- Structural integrity and morphology
- Cell viability and stability over time
By introducing controlled fluid dynamics, the system provides a more predictive in vitro environment for studying tumor biology and drug response.
Key findings and relevance for cancer research
Results highlight that the incorporation of physiological flow conditions significantly enhances the biological relevance of 3D tumor models.
This supports the use of organ-on-chip and NAM-based approaches as more predictive tools for translational cancer research and in vitro drug testing, reducing the limitations associated with static culture systems.
