Solution Overview

Problem

Current methods for treating age-related organ or tissue dysfunction, such as cognitive impairment and cardiac issues, face challenges due to ABO blood group incompatibilities and complications like graft versus host disease in parabiosis, making practical application of young blood transfer impractical.

Innovation Solution

Administration of nonviable pluripotent stem cells, either lethally irradiated or lyophilized, to provide a physiologically younger phenotype and function to organs or tissues, improving age-related declines without the need for immune suppression or risk of adverse reactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If parabiosis (surgical joining of two animals to share circulation) is used to transfer young blood cells to reverse aging, then age-related organ dysfunction is improved, but ABO blood group incompatibilities and graft versus host disease occur

Engineering Contradiction:

Improveeffectiveness of aging reversalVSAvoidimmune rejection and graft versus host disease

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the therapeutic approach by separating the beneficial factors (young blood cells and their secreted factors) from the harmful components (immune cells that cause rejection). This is achieved through apheresis to isolate specific cell populations and through in vitro culture methods that enrich for regenerative cells while excluding immune cells, thereby resolving the contradiction between therapeutic effectiveness and immune compatibility

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary approach by using apheresis-derived cell products as a mediator between young and old organisms. Instead of direct parabiosis, the young blood cells are processed through apheresis to create a purified cell product that can be safely administered to the older organism, eliminating direct immune interaction while preserving the rejuvenating effects

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If parabiosis is used to transfer young blood cells, then cognitive function and organ regeneration are improved, but the procedure is complicated by immune cell attacks on older organism's organs

Engineering Contradiction:

Improverate of tissue regeneration and cognitive improvementVSAvoidcomplexity of surgical procedure and immune management

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts only the beneficial regenerative cell components from young blood through apheresis, separating them from the harmful immune cells. This extraction process creates a purified cell product that maintains the ability to promote tissue regeneration and cognitive improvement while eliminating the complexity of managing immune rejection and surgical complications associated with full parabiosis

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If viable pluripotent stem cells are transplanted to improve age-related dysfunction, then tissue regeneration occurs, but immune suppression is required and adverse reactions risk increases

Engineering Contradiction:

Improveefficacy of tissue repairVSAvoidimmune suppression requirements and adverse reaction risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional approach by using nonviable (dead) pluripotent stem cells instead of viable ones. These nonviable cells are processed through apheresis and administered as a therapeutic product. The dead cells release beneficial factors and stimulate regeneration without posing immune rejection risks, thereby eliminating the need for immune suppression while maintaining tissue repair efficacy

Inventive Principle:

Principle #13The other way round (Inversion)
