Solution Overview

Problem

Existing cellular mesenchymal stem cell (MSC) therapies for treating wounds, inflammatory conditions, and autoimmune diseases suffer from therapeutic loss and require tissue matching, necessitating the development of acellular MSC-derived products that provide similar benefits without these drawbacks.

Innovation Solution

Development of MSC secretome compositions, including growth factors, exosomes, and extracellular vesicles, which can be frozen or powdered, and are incorporated into various medical devices for localized treatment of wounds, orthopedic, and spinal disorders, using standard or artificial wound healing conditions to enhance production and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cellular MSC therapies are used to treat wounds and inflammatory conditions, then therapeutic benefits are provided, but therapeutic loss occurs and tissue matching is required

Engineering Contradiction:
Improvetherapeutic benefitVSAvoidtherapeutic loss
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent extracts the therapeutic components (growth factors, extracellular vesicles, secretome) from the cellular MSC structure, creating an acellular preparation that retains therapeutic benefits while eliminating cell attrition and tissue matching requirements. This is achieved through isolation and concentration of MSC-derived bioactive molecules and vesicles.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a copy of the therapeutic function by using acellular MSC-derived preparations that replicate the immunomodulatory and regenerative effects of living MSCs without requiring viable cells. The growth factors and extracellular vesicles serve as functional copies of cellular therapy.

Inventive Principle:
Principle #26Copying

2Reliability

If cellular MSC therapies are used, then therapeutic benefits are provided, but tissue matching between donor and recipient is necessary

Engineering Contradiction:
Improvetherapeutic benefitVSAvoidtissue matching complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the cellular component that necessitates tissue matching, extracting only the secreted therapeutic molecules and extracellular vesicles. This acellular approach eliminates immunological compatibility concerns while preserving therapeutic efficacy.

Inventive Principle:
Principle #2Taking out (Extraction)

3Stability of the object's composition

If MSC secretome compositions are frozen or powdered for storage, then stability and ease of storage are improved, but degradation of growth factors and extracellular vesicles may occur

Engineering Contradiction:
Improvestorage stabilityVSAvoidgrowth factor integrity
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent applies protective coatings and stabilizing formulations to the MSC secretome compositions before freezing or powdering. This preliminary protection prevents degradation during storage and ensures growth factor integrity when the product is later reconstituted and used.

Inventive Principle:
Principle #10Preliminary action

4Quantity of substance

If MSC preparations are cultured under artificial wound healing conditions, then production of growth factors and extracellular vesicles is enhanced, but culturing complexity increases

Engineering Contradiction:
Improvegrowth factor productionVSAvoidculturing conditions complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent modifies culturing parameters (such as oxygen tension, nutrient composition, and growth factors in the medium) to create artificial wound healing conditions that stimulate enhanced production of growth factors and extracellular vesicles by MSCs, optimizing the secretome composition for therapeutic use.

Inventive Principle:
Principle #35Parameter changes
