Electroacupuncture Mobilization of Mesenchymal Stem Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively increase mesenchymal stem cell (MSC) levels in the blood of mammals for therapeutic use, as they are undetectable in healthy humans, limiting their application in tissue regeneration and repair.
Innovation Solution
Electroacupuncture (EA) stimulation is applied to specific acupuncture points (LI-4, LI-11, GV-14, and GV-20) to mobilize MSCs into the bloodstream, allowing for their isolation and expansion, and subsequent use in treating damaged tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional methods are used to obtain MSCs, then MSC levels remain undetectable in the blood of healthy humans, but the patent applies electroacupuncture stimulation to mobilize MSCs into the bloodstream, achieving detectable and isolatable levels
Solution Approach 1:
The patent applies electroacupuncture stimulation as a preliminary action to mobilize MSCs from bone marrow into the bloodstream before collection. This pre-mobilization step ensures that sufficient MSCs are present in the blood for subsequent isolation and therapeutic use, resolving the contradiction between undetectable baseline levels and the need for detectable quantities.
2Manufacturing precision
If MSCs are isolated and expanded from blood, then high purity MSC populations can be obtained for therapy, but the process requires multiple steps including blood collection, separation, and culture expansion
Solution Approach 1:
The patent uses electroacupuncture stimulation as an intermediary mechanism to facilitate MSC mobilization into the bloodstream. This intermediary approach enables subsequent isolation using standard blood separation techniques, achieving high purity MSC populations while utilizing established medical procedures rather than requiring entirely new complex systems.
3Reliability
If MSCs are used for tissue repair, then damaged tissue can be treated, but MSC levels must first be increased from undetectable to therapeutic amounts
Solution Approach 1:
The patent implements preliminary electroacupuncture stimulation to rapidly mobilize and accumulate MSCs in the bloodstream before therapeutic administration. This pre-accumulation phase ensures that sufficient quantities of MSCs are available for effective tissue repair, resolving the contradiction between needing high reliability for repair and the slow rate of natural MSC accumulation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
EA effectively increases MSC levels in the blood, enabling their isolation and expansion to a high purity, which can be used to treat damaged tissues by direct injection or other administration methods, enhancing tissue repair and regeneration.
Implementation Method 1
contacting two or more acupuncture points selected from the group consisting of LI-4, LI-11, GV-14, and GV-20 on the mammal with a therapeutically effective amount of EA stimulation to mobilize MSCs into the blood of the mammal
Data Source
AI summary
Stimulation using EA of LI-4, LI-11, GV-14 and GV-20 in humans, horses, and rodents results in mobilization of MSCs into systemic circulation. Methods are provided for increasing mesenchymal stem cells in the circulating blood of a mammal by contacting acupuncture points LI-4, LI-11, GV-14, and GV-20 of the mammal with a therapeutically effective amount of EA stimulation to mobilize MSCs into the circulating blood of the mammal. Methods for treating damaged tissue, specifically damaged tendons are also provided. Isolated mesenchymal stem cells made according to these methods, methods of isolated them, and stem cell banks that store them are also provided.
