Parallel Cell Culture System Serum-Free Medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing meat and other products using cell culture systems rely on animal-derived serum, such as fetal bovine serum, which is expensive, variable, and raises ethical concerns regarding animal harm, while also contributing to environmental degradation. Additionally, these methods face challenges in efficiently and cost-effectively growing large numbers of adherent cells for tissue constructs.
Innovation Solution
A large-scale cell culture system that connects multiple vessels in parallel or series to culture various cell types simultaneously, using a serum-free medium that includes non-animal derived growth factors, allowing for efficient secretion of growth factors and cytokines into a conditioned medium, which can be used for producing meat, personal care products, and nutritional supplements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If animal-derived serum (e.g., fetal bovine serum) is used in cell culture medium, then cell growth and proliferation are supported, but ethical concerns regarding animal harm arise and environmental degradation occurs
Solution Approach 1:
The patent extracts and removes the animal-derived serum component from the cell culture medium, replacing it with a serum-free formulation. This extraction eliminates the ethical and environmental harms associated with animal slaughter while maintaining cell culture functionality through alternative growth factors and cytokines.
Solution Approach 2:
The patent introduces conditioned medium containing growth factors and cytokines as an intermediary substance to replace animal serum. This conditioned medium acts as a mediator that provides the necessary biological signals for cell growth and proliferation without requiring animal-derived components.
2Reliability
If animal-derived serum is used in cell culture medium, then cell culture can proceed, but the cost becomes expensive and variability increases
Solution Approach 1:
The patent removes the expensive and variable animal serum from the culture medium formulation, replacing it with cost-effective, consistent plant-derived or synthetically produced growth factors and cytokines, thereby reducing production costs and improving batch-to-batch consistency.
Solution Approach 2:
The patent changes the chemical composition parameters of the culture medium by substituting animal serum with alternative growth factors and cytokines, thereby altering the medium's properties to achieve lower cost and higher consistency while maintaining cell culture functionality.
3Productivity
If large numbers of adherent cells are cultured for tissue constructs, then meat production scale is achieved, but the complexity of the culture system increases
Solution Approach 1:
The patent segments the culture system into multiple connected vessels that can be arranged in parallel or series configurations. This segmentation allows the system to scale up cell production capacity while managing complexity through modular design, where each vessel can be independently optimized and maintained.
Solution Approach 2:
The patent creates a universal culture system where multiple vessels share common infrastructure (pumping, heating, gas supply) but can independently culture different cell types or conditions. This multi-functionality allows the system to achieve high productivity for meat production while reducing overall complexity through shared components.
4Manufacturing precision
If multiple cell types are cultured simultaneously for tissue constructs, then product quality improves, but the culture system complexity increases
Solution Approach 1:
The patent divides the culture system into separate vessels for different cell types, allowing each cell type to be cultured under its optimal conditions. This segmentation improves tissue construct quality by ensuring proper differentiation and function of each cell type while managing complexity through standardized vessel designs and protocols.
Solution Approach 2:
The patent merges multiple single-cell-type culture systems into a connected multi-vessel system that shares common infrastructure. This combining approach allows simultaneous cultivation of different cell types for high-quality tissue constructs while reducing overall complexity through shared pumping, heating, and gas supply systems.
