Cardiac Stem Cells with Enhanced Angiogenic Potential
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current therapeutic methods are inadequate for effectively promoting angiogenesis, which is crucial for wound healing and tissue regeneration, as they often fail to adequately address the non-formation of blood vessels leading to conditions like myocardial infarction and angina pectoris.
Innovation Solution
A pharmaceutical composition comprising cardiac stem cells transformed with genes encoding growth factors such as HIF-1α, VEGF, PDGF, HGF, or FGF, which are characterized by enhanced angiogenic potential, or their culture broth, used to treat angiogenesis-dependent diseases by promoting angiogenesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional therapeutic methods are used to promote angiogenesis, then treatment of angiogenesis-dependent diseases is attempted, but the methods are inadequate and fail to effectively promote angiogenesis and tissue regeneration
Solution Approach 1:
The patent transforms cardiac stem cells with genes encoding growth factors (HIF-1α, VEGF, PDGF, HGF, FGF) to alter their biological parameters, enhancing their angiogenic potential and effectiveness in promoting blood vessel formation and tissue regeneration
Solution Approach 2:
The patent creates a composite therapeutic system combining cardiac stem cells with multiple growth factor genes, where the synergistic interaction of different growth factors enhances the overall angiogenic effect beyond what single factors could achieve
2Reliability
If angiogenesis is not properly formed, then blood supply to tissues is insufficient, but developing therapeutic methods to induce angiogenesis is complex and challenging
Solution Approach 1:
The transformed cardiac stem cells autonomously secrete multiple growth factors that create a self-sustaining angiogenic environment, eliminating the need for complex external therapeutic interventions and continuously promoting blood vessel formation
Solution Approach 2:
The cardiac stem cells are engineered to perform multiple functions simultaneously: they differentiate into cardiac cells, secrete multiple growth factors (VEGF, PDGF, HGF, FGF), and promote both angiogenesis and tissue regeneration, simplifying the therapeutic approach
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
The cardiac stem cells with enhanced angiogenic potential significantly activate angiogenic genes, leading to improved angiogenesis, wound healing, and tissue regeneration, effectively treating conditions such as wounds, chronic ulcers, and myocardial infarction by restoring damaged blood vessels and reducing tissue damage.
Implementation Method 1
Angiogenesis, as a phenomenon wherein endothelial cells of pre-existing blood vessels degrade the extracellular matrix, migrate, divide, and differentiate to form new capillary vessels
Implementation Method 2
endothelial cells of pre-existing blood vessels degrade the extracellular matrix, migrate, divide, and differentiate to form new capillary vessels
Implementation Method 3
endothelial cells of pre-existing blood vessels degrade the extracellular matrix, migrate, divide, and differentiate to form new capillary vessels
