Solution Overview
Problem
Current methods for growing organoids in arrays face limitations such as inadequate mimicry of native microenvironments, artifacts from Matrigel, and heterogeneity in viability, size, and shape, which hinder high-throughput analysis and pharmaceutical drug screening.
Innovation Solution
A high-throughput microwell platform using bioengineered hydrogels allows for the reproducible growth of organoids in situ, enabling controlled formation and co-culture with stromal cells, and facilitates automated analysis by maintaining organoids within a single focal plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional plastic microwell arrays are used for organoid culture, then high-throughput screening capability is achieved, but organoid formation is inhibited due to inadequate mimicry of native microenvironment
Solution Approach 1:
The invention changes the material parameter of the microwell array from conventional plastic to bioengineered hydrogel, which fundamentally alters the microenvironment properties to better mimic native tissue conditions while preserving the array format for high-throughput applications
Solution Approach 2:
The invention uses composite hydrogel materials that combine the structural properties needed for microwell formation with bioactive components that support organoid development, creating a material system that satisfies both high-throughput and biological fidelity requirements
2Reliability
If Matrigel is used as culture matrix, then organoid growth is supported, but artifacts are introduced that compromise data quality
Solution Approach 1:
The invention replaces Matrigel with synthetic hydrogel materials that can be precisely controlled and discarded, eliminating batch-to-batch variability and unknown components present in Matrigel while maintaining organoid growth support
Solution Approach 2:
The invention changes the chemical composition parameters of the culture matrix from animal-derived Matrigel to defined synthetic hydrogels, eliminating artifacts while preserving essential growth-supporting properties through controlled material design
3Productivity
If stem cells are seeded directly into conventional microwells, then high-throughput format is maintained, but organoid heterogeneity increases in viability, size, and shape
Solution Approach 1:
The invention applies local quality control by engineering specific regions within each microwell to have optimized properties for uniform organoid formation, ensuring consistent cell aggregation and development across all wells while maintaining high-throughput format
Solution Approach 2:
The invention performs preliminary action by pre-characterizing and standardizing the hydrogel microwell properties before cell seeding, ensuring that each well is prepared with optimal conditions for producing uniform organoids, thereby reducing heterogeneity in the final product
4Reliability
If organoids are grown in three-dimensional matrices, then biological fidelity is improved, but automated imaging and analysis become difficult
Solution Approach 1:
The invention segments the three-dimensional growth environment into discrete microwell compartments within an array, allowing each organoid to develop in 3D while maintaining a structured, addressable format that simplifies automated imaging and data analysis
Solution Approach 2:
The invention organizes three-dimensionally grown organoids into a two-dimensional array layout, enabling the preservation of 3D biological fidelity while adding the organizational dimension of spatial regularity that facilitates automated microscopy and high-throughput analysis
