Frame-Based Cell Holding Material for Unobstructed Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cell holding techniques require scaffolds that obstruct cell observation, necessitating a solution that allows cells to be held without such obstacles.
Innovation Solution
A cell holding material and method involving a frame member that surrounds or partially surrounds a cell population, allowing cells to be held in a medium or spheroid form with contact at the margin and without physical support, enabling long-term observation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a scaffold is used to hold cells, then cells can be held at a desired position, but the scaffold becomes an obstacle during cell observation
Solution Approach 1:
The invention extracts and removes the scaffold component from the cell holding system. Instead of using a scaffold to hold cells, the patent employs a frame member that defines a holding region where cells are held by adhesion to the frame member's surface or by aggregation within the defined space, eliminating the need for internal scaffolding structures that would obstruct observation
Solution Approach 2:
The frame member acts as a thin boundary structure that defines the holding region without providing internal support that would block views. The frame member's thin profile allows optical penetration from multiple directions, enabling clear observation of cells from above and below without scaffold interference
2Ease of operation
If cells are held using conventional methods, then cells can be positioned, but observation is obstructed by the holding structure
Solution Approach 1:
The invention segments the cell holding function from the observation path. The frame member divides space to define a holding region, while keeping the interior space open and free of obstructions. This segmentation allows cells to be positioned within the defined region while maintaining unobstructed optical access from multiple directions
Solution Approach 2:
The frame member provides cell positioning through spatial definition in three-dimensional space rather than through physical support structures. By defining a holding region boundaries, the frame member enables cell positioning while maintaining optical accessibility from above, below, and through the open interior space

AI summary
A cell holding material capable of holding cells, in which a scaffold to which the cells adhere does not become an obstacle to cell observation, and a cell holding method therefor are provided. A certain embodiment of the present invention is a cell holding material, including a frame member for surrounding all or at least part of a planned holding region capable of holding a cell population obtained by aggregating multiple cells, and the cell population in a form of membrane occupying at least part of the planned holding region and being held by the frame member, in which at least part of a margin of the cell population is brought into contact with the frame member, and further a portion occupying the planned holding region in the cell population is in a state of being hung without physical support.
