TCM Mixture for Stem Cell Cardiomyocyte Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for heart failure, particularly post-myocardial infarction, face challenges in long-term survival of transplanted cardiomyocytes due to harsh micro-environmental conditions and the need for large numbers of functionally mature cardiomyocytes, which are difficult to obtain through in-vitro induction.
Innovation Solution
A traditional Chinese medicine mixture comprising syngnathus, cornu cervi pantotrichum, hippocampus, ginseng, astragalus, epimedium, salvia miltiorrhiza, gynostemma pentaphyllum, and saussurea involucrata, along with a chemical compound derived from velvet antler polypeptide and syngnathus extract, is used to promote directional differentiation of stem cells into high-purity, functionally mature cardiomyocytes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If in-vitro induction of stem cells into cardiomyocytes is performed, then cardiomyocytes can be obtained for transplantation, but the differentiation rate is low and the cells lack functional maturity
Solution Approach 1:
The patent applies parameter changes by introducing a traditional Chinese medicine compound containing multiple active ingredients (icariin, ginsenoside Rg1, salvianolic acid B, etc.) that modify the differentiation conditions. This chemical parameter change promotes both the differentiation rate and functional maturity of cardiomyocytes, resolving the contradiction between productivity and manufacturing precision.
Solution Approach 2:
The patent uses a composite traditional Chinese medicine compound consisting of multiple extracted ingredients working synergistically. This composite approach combines the effects of different chemical compounds to simultaneously enhance differentiation rate and functional maturity, addressing both aspects of the technical contradiction.
2Quantity of substance
If large numbers of cardiomyocytes are needed for transplantation, then cell production quantity increases, but the harsh micro-environment leads to low survival rate and apoptosis
Solution Approach 1:
The patent applies preliminary action by pre-treating stem cells with the traditional Chinese medicine compound during the differentiation process. This preliminary exposure to the compound enhances the cells' resistance and adaptability before transplantation, improving their survival rate in the harsh post-transplantation micro-environment while maintaining large-scale production.
Solution Approach 2:
The traditional Chinese medicine compound acts as a protective cushioning agent that prepares cardiomyocytes for the stressful transplantation environment. The compound's ingredients (icariin, ginsenoside Rg1, salvianolic acid B) provide beforehand protection against apoptosis and environmental stress, ensuring higher reliability for large numbers of transplanted cells.
