Time-Lapse Observation of iPS Cell Expression With Adaptive Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current living sample observing apparatuses are inefficient in monitoring the low-frequency expression of induced pluripotent stem cells (iPS cells) due to their irregular expression in incubation containers, making it difficult to effectively observe the processes of gene expression and silencing.
Innovation Solution
An observing apparatus with a first unit for time-lapse shooting of a predetermined area, a first discriminating unit to identify the expression of a material, and a second unit for high-frequency time-lapse shooting when the material is expressed, allowing for targeted and detailed observation of iPS cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single observing unit performs time lapse shooting of the entire observation area, then the observation coverage is complete, but the shooting frequency is too low to effectively capture irregularly expressed iPS cells
Solution Approach 1:
The observation area is divided into multiple regions, with a first observing unit covering the entire area and a second observing unit focusing on specific regions of interest. This segmentation allows the second unit to achieve higher shooting frequency in targeted areas without sacrificing overall coverage.
Solution Approach 2:
The system adds a spatial dimension to the observation strategy by introducing a second observing unit that focuses on specific regions. This creates a hierarchical observation structure where different units operate at different spatial scales (whole area vs. specific regions) to simultaneously achieve comprehensive coverage and high-frequency monitoring.
2Measurement precision
If the shooting frequency is increased throughout the entire observation area, then the detection of iPS cell expression is improved, but the resource consumption and data volume increase significantly
Solution Approach 1:
The system applies different observation strategies to different regions: the first observing unit performs low-frequency shooting across the entire area, while the second observing unit performs high-frequency shooting only in regions where iPS cells are detected. This local quality approach optimizes resource allocation by concentrating detailed observation only where needed.
Solution Approach 2:
The first observing unit performs preliminary low-frequency screening to identify regions with iPS cell expression. Based on these preliminary results, the second observing unit is activated to perform detailed high-frequency observation in the identified regions, avoiding unnecessary high-frequency shooting in areas without iPS cells.
3Device complexity
If a single observing unit is used, then the device complexity is low, but the ability to perform both wide-area monitoring and detailed observation is insufficient
Solution Approach 1:
The first observing unit serves multiple functions: it performs wide-area monitoring, identifies regions of interest, and provides baseline data. The second observing unit complements this by providing detailed high-frequency observation. Together, they create a multi-functional observation system that handles both survey and detailed inspection tasks.
Solution Approach 2:
The observation system is structured hierarchically with the first observing unit providing overall coverage and the second observing unit nested within specific regions. The second unit's observation area is a subset of the first unit's area, creating a nested structure that efficiently organizes observation resources at different scales.

AI summary
A certain material irregularly expressed in an observation area is effectively observed. An observing apparatus includes a first observing unit performing a time lapse shooting of a predetermined observation area, a first discriminating unit discriminating whether or not a first material is expressed in the observation area based on an image obtained by the first observing unit, and a second observing unit starting a time lapse shooting relating to a part where the first material is expressed at a timing when the first material is expressed in the observation area, in which a shooting frequency of the time lapse shooting by the second observing unit is higher than a shooting frequency of the time lapse shooting by the first observing unit.
