Solution Overview

Problem

Current methods for promoting bone growth, regeneration, and repair lack effective cell-derived compositions that can up-regulate genes crucial for these processes, particularly in a safe and sustainable manner suitable for human clinical use.

Innovation Solution

A novel cell-derived composition, Amnion-derived Cellular Cytokine Solution-B (ACCS-B), is created by culturing Amnion-derived Multipotent Progenitor (AMP) cells in Basal Medium Eagle culture medium supplemented with human serum albumin and recombinant human EGF, which up-regulates genes important for bone growth and repair, and is formulated for sustained release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If standard cell culture methods are used, then the culture process is simple and rapid, but genes important for bone growth and repair are not up-regulated

Engineering Contradiction:
Improvegene up-regulationVSAvoidculture condition complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by modifying culture medium composition (adding specific growth factors like FGF-2, VEGF, TGF-β3), culture conditions (temperature, pH, oxygen levels), and cell handling protocols to up-regulate bone-related genes. These controlled parameter changes transform standard culture methods into a specialized system that achieves the desired gene expression without excessive complexity.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If cell-derived compositions are developed for bone repair, then bone growth and regeneration are promoted, but safety and sustainability for human clinical use are concerns

Engineering Contradiction:
Improvetherapeutic safetyVSAvoidbone regeneration efficacy
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent extracts and isolates specific bone-regulating factors from cell culture media through purification processes. This extraction allows the identification and separation of active components (such as growth factors and cytokines) from the complex culture medium, enabling the development of purified therapeutic preparations that maintain efficacy while improving safety and sustainability for clinical applications.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates copies of natural bone-regulating molecules through recombinant DNA technology and cell-based production systems. By copying and producing these factors in controlled laboratory conditions, the patent achieves safe and sustainable therapeutic sources that replicate the beneficial effects of natural bone repair mechanisms without the risks associated with uncontrolled cell-derived products.

Inventive Principle:
Principle #26Copying

3Reliability

If AMP cells are cultured under specific conditions to up-regulate bone genes, then bone growth and repair are promoted, but the culture process becomes more complex and time-consuming

Engineering Contradiction:
Improvebone repair promotionVSAvoidculture time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-treating AMP cells with bone-stimulating factors and optimizing culture conditions before the actual bone repair process. This includes pre-seeding cells with growth factors, pre-adjusting media composition, and pre-establishing optimal culture parameters, which accelerates subsequent bone regeneration while maintaining reliability.
