Apoptotic Vesicles Stimulate Cell Proliferation for Tissue Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective solutions for promoting cell proliferation in injured or diseased tissues, particularly in conditions like diabetic ulcers, where compensatory proliferation signaling (CPS) mechanisms are not fully understood or utilized.
Innovation Solution
Administration of purified apoptotic compensatory proliferation signaling vesicles (ACPSVs), which are Crkl-containing microvesicles derived from apoptotic cells, to stimulate proliferation in neighboring cells, potentially through topical formulations like gels or creams, facilitating tissue repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods are used to treat injured or diseased tissue, then treatment is provided, but cell proliferation is not effectively promoted
Solution Approach 1:
The patent utilizes apoptotic cells (harmful/damaging element) to produce ACPSVs that stimulate compensatory proliferation in neighboring cells. The apoptotic cells are converted into a beneficial therapeutic agent by harvesting their vesicles, which then promote tissue repair and cell proliferation in the injured area, transforming the harmful apoptosis process into a healing mechanism.
Solution Approach 2:
ACPSVs serve as an intermediary between apoptotic cells and living recipient cells. The vesicles carry signaling molecules that mediate the communication from apoptotic cells to surviving cells, triggering compensatory proliferation without direct cell-to-cell contact. This intermediary mechanism effectively promotes tissue repair by bridging the gap between cell death and tissue regeneration.
2Productivity
If apoptotic cells are used to induce compensatory proliferation, then cell proliferation increases, but the mechanism is not fully understood or utilized
Solution Approach 1:
The patent segments the complex apoptotic cell into its functional components, specifically isolating and purifying the ACPSVs from the apoptotic cell mixture. By separating the vesicles from other apoptotic debris and components, the invention enables focused study and application of the specific proliferative signaling mechanism, making the previously unobservable CPS process detectable and可利用able.
Solution Approach 2:
The patent extracts ACPSVs from apoptotic cells through purification processes that isolate the vesicles containing compensatory proliferation signaling molecules. This extraction allows the CPS mechanism to be studied independently and applied therapeutically without the complexity of whole apoptotic cells, enabling both understanding and utilization of the mechanism.
3Reliability
If ACPSVs are administered to promote tissue repair, then wound healing enhances, but formulation and delivery methods are required
Solution Approach 1:
The patent develops topical formulations (gels, creams, ointments) that can deliver ACPSVs to various types of injured or diseased tissues through a single application method. These formulations are designed to be universally applicable to different wound types and locations, providing multi-functional delivery that simplifies the overall treatment approach while maintaining effective ACPSV delivery to promote tissue repair.

AI summary
Methods of administering apoptotic compensatory proliferation signaling vesicles (AC PS Vs), and pharmaceutical formulations thereof, are described herein. AC PS Vs can be used to promote proliferation of cells in injured or diseased tissues, for example by adding a therapeutically effective amount of APCSVs to the injured or diseased tissue.
