Exosome Bone Graft Composition for Stable Vesicle Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exosomes are fragile vesicles that require a suitable environment to maintain their integrity for therapeutic use, and existing bone graft materials do not effectively preserve their structure and functionality.
Innovation Solution
A bone graft material comprising an exosome mixture with dimethyl sulfoxide, epsilon poly L-lysine, and natural or man-made bone materials, which stabilizes and maintains the integrity of exosomes, allowing them to function effectively in bone graft applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If exosomes are used in therapeutic compositions, then bone regeneration is enhanced, but exosome integrity is difficult to maintain
Solution Approach 1:
The patent uses dimethyl sulfoxide (DMSO) as an intermediary substance to protect exosomes from environmental degradation. DMSO acts as a stabilizing agent that mediates between the exosomes and the external environment, preventing harmful interactions while maintaining exosome integrity and therapeutic functionality.
Solution Approach 2:
The patent creates a protective environment for exosomes by formulating them in a stable composition containing DMSO and epsilon poly L-lysine. This formulation creates an inert-like environment that shields the fragile exosomes from degradation factors, allowing them to maintain their structural integrity and biological activity during storage and application.
2Reliability
If natural bone material is used for grafting, then bone growth framework is provided, but disease transmission risk exists
Solution Approach 1:
The patent extracts and isolates exosomes from donor cells, separating the beneficial regenerative components from the harmful elements that could transmit disease. By using only the exosomal fraction rather than whole bone or tissue, the invention removes pathogens while retaining the therapeutic bone-regenerating properties.
Solution Approach 2:
The patent uses exosomes as a form of biological copy or surrogate that carries the regenerative information and signaling molecules needed for bone growth without containing the actual bone tissue that could transmit disease. The exosomes replicate the beneficial effects of bone tissue through their molecular contents rather than through direct tissue contact.
