Solution Overview

Problem

Current methods for observing sebaceous gland dynamics in a living body are inadequate, as they fail to accurately reproduce sebum production, and existing methods for observing sweat glands cannot be directly applied to sebaceous glands due to structural differences and biological interactions with substrates.

Innovation Solution

A method involving anchoring a sebaceous gland structure to a support without biological contact, using a substrate that maintains the gland's intrinsic function and structure, allowing for observation of dynamics similar to those in a living body by removing dermis and hypodermis and using a biological substrate as an anchoring member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a sebaceous gland is cultured in a medium to observe sebum production, then the gland can be maintained in vitro, but the dynamics of sebum production do not accurately resemble those in a living body

Engineering Contradiction:
Improveaccuracy of sebaceous gland dynamics observationVSAvoidreproduction of living body conditions
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

A biological substrate gel is introduced as an intermediary between the sebaceous gland and the culture medium. The gland is anchored to this gel, which provides a more physiologically relevant environment while maintaining the benefits of in vitro culture. This intermediary layer allows the gland to exhibit dynamics closer to those in a living body without requiring actual living tissue.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If a sweat gland is anchored to a support using biological substrate to prevent displacement, then accurate observation of sweat gland dynamics is achieved, but direct application of this method to sebaceous glands is not feasible due to structural differences

Engineering Contradiction:
Improveaccuracy of gland dynamics observationVSAvoidapplicability across different gland types
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The method applies different anchoring strategies suited to each gland type's specific characteristics. For sebaceous glands, which have different structural properties compared to sweat glands, the protocol adjusts the anchoring approach while maintaining the core principle of preventing displacement. This allows the method to be adapted to various gland types while preserving measurement accuracy for each specific application.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If sebaceous gland cells are isolated and cultured to measure lipid content, then sebum production can be quantified, but the complex dynamics of the intact sebaceous gland structure cannot be observed

Engineering Contradiction:
Improvesebum production measurementVSAvoidintact gland structure maintenance
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The observation system is segmented into distinct functional components: the intact sebaceous gland structure is maintained for observing dynamics, while separate quantification methods (such as lipid staining and imaging) are applied to measure sebum production. This segmentation allows both the complexity of the intact structure and the precision of quantitative measurement to be achieved simultaneously through coordinated use of multiple techniques.

Inventive Principle:
Principle #1Segmentation

AI summary

Provided is a method for observing a sebaceous gland, the method making it possible to observe dynamics of a sebaceous gland which dynamics are close to dynamics of a sebaceous gland in a living body. The method includes: an anchoring step of anchoring a sebaceous gland structure to a support so that a sebaceous gland that is included in the sebaceous gland structure and is to be observed and the support are not in biological contact with each other, the sebaceous gland structure being obtained by removing all or part of each of dermis and hypodermis from a skin tissue; and an observation step of observing the sebaceous gland structure obtained in the anchoring step.
