Cellular Factor Solution Compositions for Wound Healing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protein-based therapeutic agents, such as cytokines and growth factors, fail to administer physiologically relevant levels effectively due to high doses and instability issues, leading to incomplete recreation of physiological niches and increased risk of protein denaturation.
Innovation Solution
Development of novel cellular factor-containing solution compositions (CFS) and sustained-release cellular factor-containing solution compositions (SR-CFS) that mimic the complex and unique combination of cytokines and growth factors found in biological niches, using amnion-derived cellular cytokine solutions with specific concentrations of VEGF, TGFβ2, Angiogenin, PDGF, TIMP-1, and TIMP-2, and methods for pooling and sustained-release formulation to maintain consistent therapeutic levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high doses of individual cytokines and growth factors are administered, then therapeutic effect is enhanced, but protein denaturation risk increases and physiological balance is disturbed
Solution Approach 1:
The patent combines multiple cytokines and growth factors (PDGF-BB, GM-CSF, HGH, and others) into a single composition that mimics the complex physiological niche. This merging approach allows delivery of physiologically relevant combinations at appropriate concentrations rather than high doses of single factors, reducing denaturation risk while maintaining therapeutic efficacy through synergistic interactions.
Solution Approach 2:
The invention changes the concentration parameters from high single-factor doses to physiologically relevant low-level combinations. The composition delivers multiple factors at concentrations that mimic in vivo levels, fundamentally altering the dosing paradigm to reduce protein stress and denaturation while achieving therapeutic effects through coordinated action of multiple factors.
2Duration of action of moving object
If sustained-release formulations are developed, then therapeutic levels are maintained over time, but formulation complexity increases
Solution Approach 1:
The composition serves multiple functions simultaneously: it provides sustained-release delivery, maintains physiologically relevant concentrations of multiple factors, and mimics the complex physiological niche. The single composition integrates what would otherwise require multiple separate delivery systems, reducing overall complexity while achieving sustained therapeutic effects.
3Reliability
If complex combinations of cytokines and growth factors are used, then physiological niche recreation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent uses cell culture systems to pre-assemble the complex combination of cytokines and growth factors in physiologically relevant proportions. The biological system naturally produces and secretes multiple factors at appropriate concentrations, performing the complex mixing and concentration adjustment beforehand, which simplifies downstream manufacturing and quality control.
