Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-dimensional cell culture models fail to accurately recapitulate the complex in vivo tumor-immune interactions, limiting their predictive ability in cancer research and clinical translation, while animal models have limited human relevance.
Innovation Solution
Development of three-dimensional tumor-immune cell cultures from patient-derived tumor and whole blood samples, which are quickly prepared to maintain native cell functionality, allowing real-time imaging and analysis of immune-tumor interactions, and testing therapeutic efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two-dimensional cell culture models are used, then cost effectiveness and high-throughput capability are improved, but the ability to recapitulate complex in vivo tumor-immune interactions deteriorates
Solution Approach 1:
The patent transitions from two-dimensional monolayer cell cultures to three-dimensional spheroid cultures, allowing cells to organize in spatial structures that better mimic in vivo tumor architecture. This dimensional change enables preservation of complex cell-cell and cell-microenvironment interactions while maintaining culturable systems for research applications.
Solution Approach 2:
The patent modifies critical parameters including cell density, spatial arrangement, and microenvironmental conditions to create 3D spheroids that accurately replicate in vivo tumor physiology. These parameter changes enable the system to maintain predictive ability for immune-tumor interactions while remaining suitable for high-throughput screening.
2Reliability
If animal models are used, then in vivo relevance is improved, but human specificity and predictive ability for human cancer immunosurveillance deteriorates
Solution Approach 1:
The patent creates patient-derived 3D spheroid models that copy the specific molecular and cellular characteristics of human tumors, including tumor cell lineages, immune cell compositions, and microenvironmental features. These human-specific models replicate in vivo tumor-immune interactions without the translation problems inherent in animal models.
Solution Approach 2:
The patent segments the complex in vivo tumor microenvironment into isolated 3D spheroid cultures containing specific combinations of tumor cells, immune cells, and stromal elements. This segmentation allows human-specific biological processes to be studied in controlled settings while maintaining relevance to in vivo conditions.
3Reliability
If rapid culture preparation is implemented, then cell native functionality is maintained, but culture complexity and preparation time management deteriorates
Solution Approach 1:
The patent performs preliminary actions including pre-plating cells at optimized densities, pre-preparing hydrogel matrices, and pre-establishing culture conditions before actual experimentation begins. This allows rapid initiation of 3D spheroid formation while maintaining cell functionality, reducing the overall time loss associated with culture preparation.
Data Source
AI summary
A method of forming a three-dimensional cell culture includes obtaining a tissue sample and a matched blood sample from a patient, isolating and staining tissue-derived cells, isolating and staining immune cells, culturing the tissue-derived cells in a hydrogel, and adding at least a portion of the immune cells to the hydrogel less than 24 hours later. The method mimics an in vivo tumor-immune environment and permits analysis of tumor-immune, immune-immune, and tumor-tumor cell interactions.
