3D Cell Migration Chip (3DCM-Chip): A New Tool toward the Modeling of 3D Cellular Complex Systems

Area of Science:

• Biomaterials Science
• Cell Biology
• Cancer Research

Background:

• 3D hydrogel cultures mimic physiological environments for cell studies.
• Tailorable hydrogels allow for complex models like gel-in-gel systems.
• Microspheres encapsulating cells within a hydrogel matrix facilitate migration studies.

Purpose of the Study:

• To introduce the 3D cell migration-chip (3DCM-chip) as an advanced platform for cell migration analysis.
• To investigate the impact of co-cultured cells on cancer cell invasiveness.
• To develop predictive tumoroid models with complex cellular interactions.

Main Methods:

• Utilized a lab-on-a-chip device (3DCM-chip) for 3D cell culture and migration analysis.
• Embedded cell-laden microspheres within an outer hydrogel matrix.
• Investigated the invasiveness of MDA-MB 231 breast cancer cells in co-culture with various cell types.

Main Results:

• Demonstrated the 3DCM-chip's capability to analyze biochemical and physical stimuli effects on cell migration.
• Showcased the influence of human fibroblasts on MDA-MB 231 breast cancer cell invasiveness.
• Revealed how mesenchymal stem cells, dermal fibroblasts, and endothelial cells affect cancer cell invasion.

Conclusions:

• The 3DCM-chip provides a powerful tool for studying cell migration and invasion in complex 3D environments.
• Co-culture systems using the 3DCM-chip can generate predictive tumoroid models.
• This technology advances in vitro systems for replicating the tumor microenvironment.
