Compartmentalized Cell Culture Device for Biological Tissue Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cell culture techniques fail to compartmentalize biological tissues effectively, leading to unorganized growth of components like hair or neurons, which inaccurately models biological materials and limits specific testing capabilities.
Innovation Solution
A cell culture device with a layered structure comprising an inlet and outlet reservoir connected by a channel, designed to orient and stabilize elongated components away from multicellular components, maintaining their elongated configuration through converging portions and tubular sections, allowing for precise compartmentalization and interaction within the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cell culture techniques are used, then the culture process is simple, but the biological tissue components grow in an unorganized network that cannot accurately model the biological material
Solution Approach 1:
The device divides the cell culture chamber into distinct compartments: a first chamber for multicellular components and a second chamber for elongated components, with a selective barrier between them. This segmentation allows each component type to be cultured separately in optimized environments while maintaining overall system organization and accuracy in modeling biological tissues.
2Measurement precision
If components are compartmentalized into separate chambers, then the architecture is organized and testing precision is improved, but the device complexity increases
Solution Approach 1:
The selective barrier serves multiple functions simultaneously: it physically separates the two component types, provides structural support for the elongated components, enables controlled fluid flow between chambers, and maintains the organized architecture required for precise biological modeling. This multi-functionality reduces the need for additional separate structures.
3Stability of the object's composition
If elongated components are allowed to grow freely, then the growth process is simple, but the components cannot maintain their elongated configuration and travel past the multicellular components
Solution Approach 1:
The selective barrier acts as an intermediary structure that guides elongated components from the second chamber toward the first chamber while preventing them from traveling past the multicellular components. The barrier's geometry and positioning control the path and orientation of elongated components, maintaining their configuration without requiring complex active control mechanisms.

AI summary
There are provided cell culture devices and associated methods for preparing a compartmentalized in vitro model. The cell culture device can include a cell culture layer that includes an inlet reservoir configured for receiving an inlet fluid medium therein, an outlet reservoir configured for receiving an outlet fluid medium therein, and a channel extending between the inlet reservoir and the outlet reservoir to establish fluid communication therebetween. The channel can include a multicellular component receiving portion and an elongated component receiving portion provided downstream of the multicellular component receiving portion, the elongated component receiving portion being sized and configured for orienting an elongated component of a biological material away from the inlet reservoir. The cell culture device can further include an electrode layer provided in proximity of the cell culture layer.
