3D Tumor Models with Stromal Barriers for Therapy Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for recreating the complex tumor microenvironment in vitro are inadequate for accurately predicting the effectiveness of therapeutic approaches for individual cancer patients, as they fail to replicate the patient's own immune response and tumor architecture.
Innovation Solution
Development of three-dimensional tumor models that incorporate tissue barriers, such as stromal barriers, around tumor cells in culture, allowing for the replication of the individual's immune cell response and enabling the assessment of therapeutic efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional tumor models are created to replicate tumor architecture and immune response, then prediction accuracy of therapeutic efficacy is improved, but model complexity and manufacturing difficulty increase
Solution Approach 1:
The tumor model is divided into distinct spatial compartments: a first compartment containing tumor cells and a second compartment containing immune cells, separated by a stromal barrier layer. This segmentation allows each compartment to be optimized for its specific cell type while maintaining overall model functionality for predicting therapeutic response.
Solution Approach 2:
A stromal barrier layer is introduced as an intermediary structure between the tumor cell compartment and the immune cell compartment. This stromal barrier replicates the physical and chemical barriers found in actual tumor microenvironments, enabling the model to predict how tumors interact with and evade immune responses while maintaining distinct cellular zones.
2Adaptability or versatility
If patient-specific immune cells and stromal barriers are incorporated into the model, then relevance to individual patient response is improved, but ease of manufacture deteriorates
Solution Approach 1:
The model incorporates patient-specific elements (tumor cells, immune cells, and stromal barriers) in specific local compartments rather than uniformly throughout. Tumor cells are localized to the first compartment, immune cells to the second compartment, and stromal barriers form a distinct intermediate layer, allowing patient-specific characteristics to be integrated while maintaining standardized manufacturing protocols for each compartment.

AI summary
Systems, compositions, and methods are described that utilize three dimensional tumor models incorporating tissue barrier (such as a stromal barrier) around tumor cells in culture, which permit replication in vivo immune cell response to tumor cells. Such tumor models are used to accurately assess appropriate therapeutic modes and protocols that are likely to be effective against the individual's tumor. Such tumor models can be used to selectively expand immune cells that are responsive to tumor cells utilized in the model. Such an expanded population of immune cells can subsequently be utilized therapeutically.
