In vitro models to study natural killer cell dynamics in the tumor microenvironment

Area of Science:

• Cancer Research
• Immunotherapy
• Preclinical Models

Background:

• Immunotherapy is transforming cancer treatment, necessitating advanced preclinical research methods for solid tumors.
• Current in vitro models face challenges in evaluating complex immune responses and tumor microenvironment interactions.

Purpose of the Study:

• To review recent advances in in vitro 3D platforms for natural killer (NK) cell-based cancer immunotherapy.
• To highlight the benefits and limitations of current 3D models in preclinical immunotherapy studies.
• To discuss future directions for in vitro 3D platforms in personalized cancer immunotherapy.

Main Methods:

• Review of in vitro 3-dimensional (3D) cell culture models, including tumor spheroids and organoids.
• Integration of novel imaging-based techniques and omics analysis with 3D models.
• Focus on applications in natural killer (NK) cell immunotherapy research.

Main Results:

• In vitro 3D models like spheroids and organoids are increasingly used in immunotherapy research.
• These models facilitate evaluation of immune cell cytotoxicity, cytokine release, and tumor infiltration.
• 3D platforms enable high-throughput, high-content analysis for treatment efficacy and immune evasion studies.

Conclusions:

• In vitro 3D platforms are crucial for advancing preclinical cancer immunotherapy, especially NK cell-based strategies.
• These models offer improved representation of the tumor microenvironment and immune responses.
• Further development is needed to fully realize the potential of 3D models for personalized immunotherapy.
