Solution Overview

Problem

Current cell-based therapies for tissue damage and degenerative conditions, particularly in neurological and cardiac tissues, face challenges such as limited regenerative capacity, variability in cell product consistency, and long-term engraftment requirements, which hinder effective treatment of conditions like spinal cord injuries, Parkinson's disease, and heart diseases.

Innovation Solution

The development of stable, in vitro cultured self-renewing colony-forming somatic cells (CF-SC) and extensively expanded CF-SC (exCF-SC) that maintain substantial self-renewal capacity and lack multipotent differentiation, which are administered without long-term engraftment, using pharmaceutically acceptable carriers to modulate the production of therapeutically useful compositions for tissue repair and regeneration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If autologous cells are used for cell-based therapy, then patient-specific treatment is achieved, but manufacturing complexity and time delay increase due to patient-by-patient basis production

Engineering Contradiction:
Improvepatient-specific treatmentVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses allogeneic cells as a copy or substitute for autologous cells, creating a standardized cell product that can be manufactured once and used for multiple patients. This eliminates the need for individualized cell manufacturing while providing consistent therapeutic effect through the use of healthy donor cells that can be banked and distributed widely.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If autologous cells are used for cell-based therapy, then patient-specific treatment is achieved, but treatment time delay increases due to lag time between clinical decision and cell availability

Engineering Contradiction:
Improvepatient-specific treatmentVSAvoidtreatment time delay
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent prepares allogeneic cell products in advance before clinical need arises, allowing cells to be manufactured, quality-tested, and banked ready for immediate use. This preliminary manufacturing and banking of healthy donor cells eliminates the time delay that would otherwise occur while waiting for patient-specific cell collection, processing, and validation.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If allogeneic cells are used for cell-based therapy, then manufacturing consistency improves, but donor variability risk increases

Engineering Contradiction:
Improvecell product consistencyVSAvoiddonor variability risk
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent carefully controls and standardizes multiple parameters of the allogeneic cell manufacturing process, including donor selection criteria, culture conditions, passage numbers, and storage parameters. By establishing strict parameter ranges and quality specifications, the patent ensures consistent cell product characteristics while minimizing the impact of donor variability through standardized processing protocols.

Inventive Principle:
Principle #35Parameter changes

4Productivity

If extensively expanded CF-SC are used for therapy, then cell product availability improves, but cell differentiation capacity may be reduced

Engineering Contradiction:
Improvecell product availabilityVSAvoidcell differentiation capacity
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent extracts and utilizes only the secreted factors and trophic support properties of extensively expanded CF-SC, rather than relying on their differentiation capacity. By focusing on the paracrine effects and secretome of the cells, the patent can use highly expanded cell populations that have lost multipotent capacity but retain abundant secretory activity, thereby achieving both high productivity and therapeutic effect.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The present invention relates to methods and uses of cells for the prevention and treatment of a wide variety of diseases and disorders and the repair and regeneration of tissues and organs using low passage and extensively passaged in vitro cultured, self- renewing, colony forming somatic cells (CF-SC). For example, adult bone marrow-derived somatic cells (ABM-SC), or compositions produced by such cells, are useful alone or in combination with other components for treating, for example, cardiovascular, neurological, integumentary, dermatological, periodontal, and immune mediated diseases, disorders, pathologies, and injuries.
