Tensional Homeostasis Screening for Tissue Function Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pharmacological approaches for addressing tissue function decline or changes associated with diseases and aging are often ineffective, highlighting the need for a new concept in drug discovery and healthcare material development, particularly focusing on mechanical stress as a therapeutic target.
Innovation Solution
A method for evaluating and screening control agents for tissue morphology and function based on continuous 'tensional homeostasis', which mimics the normal mechanical stress signals experienced by the body, by applying test substances to tissues or cells expressing mechanical stress signaling molecules and evaluating their expression, activity, or intracellular localization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pharmacological approaches (small molecule compounds, nucleic acids, proteins) are used to address tissue function decline, then drug discovery can proceed with conventional methods, but therapeutic/amelioration effects are often inadequate for various diseases and aging conditions
Solution Approach 1:
The invention changes the fundamental parameter being targeted from biochemical pathways to mechanical stress parameters. By applying continuous mechanical tension to simulate physiological tensional homeostasis, the system activates mechanotransduction pathways that traditional pharmacological approaches cannot effectively engage, thereby improving therapeutic reliability for tissue function decline and aging conditions
Solution Approach 2:
The invention replaces traditional biochemical drug mechanisms with a mechanical system. Instead of using small molecules, nucleic acids, or proteins to modulate tissue function, the invention applies mechanical tension through a culture system to activate endogenous mechanotransduction pathways, providing a novel approach with broader adaptability across different disease types
2Difficulty of detecting and measuring
If transient tensile load is applied to control cellular functionality, then mechanical stress effects can be studied, but the conditions do not closely resemble the continuous tensional homeostasis experienced by living bodies
Solution Approach 1:
The invention implements continuous mechanical tension application rather than transient loading. The culture system maintains constant tension on cells throughout the experiment, accurately reproducing the continuous tensional homeostasis that exists in living bodies. This continuous action provides physiologically relevant conditions while remaining operationally simple through automated culture systems
3Measurement precision
If a new evaluation method based on tensional homeostasis is developed, then healthcare materials can be screened for mechanical stress signaling effects, but the methodology and equipment requirements increase
Solution Approach 1:
The invention uses a culture system as an intermediary between the mechanical tension application and the cell response measurement. The system includes a culture substrate, culture medium, and incubation system that together create a controlled environment for applying tension and evaluating cellular responses. This intermediary system enables precise screening while managing complexity through standardized biological assays
Solution Approach 2:
The invention creates an in vitro model that copies the physiological tensional homeostasis conditions of living bodies. By reproducing the mechanical environment and cellular responses in a controlled culture system, the invention enables accurate screening of healthcare materials without requiring complex in vivo models, thereby improving measurement precision while controlling device complexity

Function Achieved in This Case
This method identifies materials that can effectively control tissue morphology and function, addressing symptoms like wrinkles, skin fibrosis, and epithelial cell carcinoma by transmitting signals equivalent to those from continuous tensional homeostasis, thereby improving skin health and treating age-related issues.
Implementation Method 1
a culture system which comprises a culture substrate, on which a culture medium is to be added and in which a test substance is to be used; and a culture vessel, in which the culture substrate is fixed so as to allow the culture substrate to be in a state under continuous tension
Implementation Method 2
studies in recent years have revealed that mechanical stress controls the functionality of tissues or cells and is involved in aging and onset of conditions
