Selective Cell Killing for Regenerative Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tissue and organ regeneration methods fail to effectively remove inhibitory cells, leading to incomplete or unsuccessful regeneration in diseases and injuries, as they do not address the removal of partially or non-functional cells that hinder stem cell function.
Innovation Solution
The development of methods and apparatus that selectively kill partially or non-functional cells using physical, electromagnetic, chemical, or biological techniques, while preserving proliferating functional cells, to create an environment conducive to regeneration by removing inhibitory cells and structures that block stem cell action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stem cell transplant therapy is applied to replace damaged or nonfunctional cells, then cell replacement is achieved, but the presence of inhibitory cells blocks stem cell action and prevents successful regeneration
Solution Approach 1:
The invention extracts and removes inhibitory cells from the tissue environment before stem cell transplantation. By selectively eliminating these harmful cells that block stem cell action, the method creates a favorable environment for stem cell engraftment and regeneration, directly resolving the contradiction between stem cell replacement and inhibitory cell interference
Solution Approach 2:
The invention applies preliminary anti-action by removing inhibitory cells before stem cell transplantation occurs. This pre-cleaning step prevents the harmful effects of inhibitory cells from blocking stem cell action, thereby ensuring higher success rates for subsequent regenerative processes
2Reliability
If all cells in a tissue are targeted for killing to remove non-functional cells, then non-functional cells are eliminated, but functional cells are also damaged and regeneration is hindered
Solution Approach 1:
The invention applies local quality by using markers that are specifically expressed or enriched in non-functional cells, allowing selective targeting of these cells while sparing functional cells. This localized differentiation in treatment specificity resolves the contradiction between eliminating non-functional cells and preserving functional cells
Solution Approach 2:
The invention exploits parameter changes in non-functional cells (such as altered marker expression, metabolic state, or physical properties) to differentiate them from functional cells. By targeting these changed parameters, the method selectively eliminates non-functional cells while preserving functional ones, resolving the contradiction between cell elimination and tissue functionality
3Productivity
If aggressive cell killing techniques are used to rapidly remove inhibitory cells, then cell removal speed increases, but excessive inflammatory responses are triggered and regeneration is compromised
Solution Approach 1:
The invention applies partial action by using moderate, controlled cell killing techniques that are sufficient to remove inhibitory cells but not so aggressive as to trigger excessive inflammation. This balanced approach maintains productivity in cell removal while avoiding the harmful effects of overly aggressive treatment
Solution Approach 2:
The invention uses markers as intermediaries to mediate selective cell killing. These markers enable targeted recognition and elimination of inhibitory cells through more gentle, specific mechanisms rather than broad aggressive killing, thereby reducing inflammatory responses while maintaining effective cell removal

AI summary
Apparatuses, compositions and methods for removing cells which interfere with regenerative processes. The apparatuses, compositions and methods selectively kill partially functional and/or non-functional cells versus functional cells while protecting functional proliferative cells to the extent that, upon removal of the killed cells by disintegration or scavenging, functional cells replace the partially- or non-functional cells.
