Using microfluidics to investigate tumor cell extravasation and T-cell immunotherapies

Area of Science:

• Oncology
• Immunology
• Biomedical Engineering

Background:

• Understanding tumor cell extravasation and immune system interactions is key for developing targeted cancer therapies.
• Current pre-clinical models often lack the complexity to accurately mimic the tumor microenvironment.

Purpose of the Study:

• To develop novel in-vitro microfluidic assays for studying cancer cell extravasation and T-cell function.
• To evaluate the potential of these platforms for personalized medicine applications.

Main Methods:

• Created an in-vitro microfluidic assay with a microvascular network to study cancer cell extravasation.
• Developed a separate assay to screen T-cell migration and cytotoxicity for adoptive immunotherapy evaluation.
• Proposed adapting these platforms to simulate a tumor liver microenvironment, including hypoxic and inflammatory conditions.

Main Results:

• Successfully demonstrated the utility of the microfluidic assay for studying cancer cell extravasation.
• Developed a method for screening T-cell migration and cytotoxicity relevant to immunotherapy.
• Highlighted the adaptability of the platform for simulating specific tumor microenvironments.

Conclusions:

• Microfluidic platforms offer powerful tools for investigating cancer cell dynamics and immune responses.
• These assays show significant potential as pre-clinical models for personalized cancer medicine, drug testing, and engineered T-cell evaluation.
