Current methods for diagnosing neoplastic diseases, such as blood tests and imaging tests, cannot accurately evaluate the metastatic potential of cancer cells from a primary tissue, which is crucial for understanding and treating metastatic lung cancer.
Innovation Solution
A system comprising a tumor microenvironment mimicking unit with a primary tumor layer including cancer cells and vascular endothelial cells, and a metastasis layer with a gel, where the vascular endothelial cells are directed towards the metastasis layer, allowing for co-culture and measurement of cancer cell migration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If whole-body PET scan is used to evaluate metastasis, then presence of metastasis can be determined, but metastatic potential of cancer cells cannot be evaluated
Solution Approach 1:
The invention segments the evaluation process into distinct functional layers: a primary tumor layer containing cancer cells and a metastasis layer containing gel, allowing separate measurement of metastatic potential from actual metastasis detection. This segmentation enables quantitative assessment of cancer cell metastatic tendency independent of whole-body imaging limitations.
Solution Approach 2:
The invention introduces an intermediary measurement system between the cancer cells and the gel layer that quantifies metastatic potential. This intermediary mechanism (including measurement units and signal detection systems) translates biological metastatic behavior into measurable data, bridging the gap between qualitative PET scan results and quantitative potential assessment.
2Measurement precision
If traditional in vitro models and in vivo animal models are used for metastasis research, then basic metastasis processes can be studied, but accurate measurement of metastatic potential and personalized treatment evaluation are limited
Solution Approach 1:
The invention transitions from traditional 2D in vitro models to a 3D co-culture system with distinct spatial layers. Cancer cells are cultured in a primary tumor layer while a metastasis layer with gel is positioned adjacent, creating a three-dimensional architecture that more accurately replicates in vivo metastatic processes while enabling precise measurement of cell migration and potential.
Solution Approach 2:
The invention creates a simplified copy of the complex in vivo metastatic environment through controlled in vitro co-culture systems. By replicating key microenvironmental factors and cellular interactions in a laboratory setting, the system captures essential metastatic behavior without requiring complex animal models, enabling standardized measurement across different samples.
3Adaptability or versatility
If co-culture system with primary tumor layer and metastasis layer is implemented, then metastatic potential can be measured, but system complexity increases
Solution Approach 1:
The invention designs a universal co-culture platform that can accommodate various types of cancer cells and study different metastatic pathways. The standardized primary tumor layer and metastasis layer configuration can be applied across multiple experimental conditions and cell types, making the system versatile while maintaining manageable complexity through modular design.
