To evaluate the 3D organotypic tissue co-culture (3D-OTC) model for its morphological and transcriptomic comparability to primary tumor tissue and to functionally characterize distinct regions of interest, including tumor stroma and immune cell interactions.
Approach:
Key Findings:
The 3D-OTC model preserves tumor morphology and immune cell interactions, which are critical for understanding tumor behavior.
The model can be cultured for up to 21 days and supports both HPV-negative and -positive tumor samples, indicating its versatility.
Differentially expressed genes in the model may play a role in drug resistance, suggesting potential targets for therapeutic intervention.
Interpretation:
The 3D-OTC model offers a promising platform for personalized therapeutic evaluations in HNSCC, potentially improving treatment outcomes.
Limitations:
Limited data on the morphological concordance between the 3D-OTC model and primary tumor tissue, which may affect the model's predictive validity.
Insufficient understanding of the immune cell infiltrate over time, which could influence treatment responses.
Conclusion:
The study supports the use of the 3D-OTC model for advancing the understanding of HNSCC and for evaluating personalized treatment options, potentially leading to improved patient outcomes.
