Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The preparation of cardiomyocyte sheets for transplantation is time-consuming and costly, and the curative effect of transplantation cannot be evaluated until the actual treatment is performed, lacking a means for pre-evaluation.
Innovation Solution
A cell culture substrate with laminated cardiomyocyte sheets, featuring alternating strip-shaped cell adhesion and suppression regions, is used to evaluate the curative effect by aligning disease and normal cardiomyocyte sheets, allowing for pre-evaluation of transplantation efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cardiomyocyte sheets are prepared for transplantation using autologous or allogeneic cells, then the transplantation treatment can be performed, but the preparation requires time and high cost
Solution Approach 1:
The invention creates a simplified in vitro model that copies the essential features of cardiomyocyte transplantation without requiring full-scale cell differentiation and sheet preparation. The model uses small interfering RNA to replicate the therapeutic effect, eliminating the need for time-consuming autologous or allogeneic cell preparation while maintaining the core research objective of evaluating transplantation efficacy
Solution Approach 2:
The invention extracts the essential evaluation function from the complete transplantation process. By isolating the key mechanism of cardiomyocyte function assessment and implementing it through RNA interference in a simplified system, the invention removes the time-consuming steps of cell collection, differentiation, and sheet formation while preserving the ability to evaluate curative effects
