Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cell therapy products, such as mesenchymal stem cell therapies, face limitations in their ability to effectively treat hepatocellular carcinoma and multiple myeloma, with a need for new sources and approaches in preparing and using these products for medical treatments.
Innovation Solution
A composition comprising apoptotic bodies derived from various types of stem cells, including mesenchymal, embryonic, and induced pluripotent stem cells, obtained through methods like incubation in serum-free medium, thermal stress, or treatment with staurosporine, is used to treat tumor formations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If apoptotic bodies are used to treat tumors, then tumor treatment effectiveness is improved, but the complexity of preparation methods increases
Solution Approach 1:
The patent segments the complex preparation process into distinct stages: stem cell culture, apoptosis induction through multiple independent methods (serum starvation, thermal stress, chemical agents), and apoptotic body isolation. This segmentation allows each step to be optimized independently while maintaining overall effectiveness in treating hepatocellular carcinoma and multiple myeloma.
Solution Approach 2:
The patent employs parameter changes to induce apoptosis under controlled conditions: varying temperature parameters (thermal stress at different temperatures and durations), chemical parameters (staurosporine concentration and exposure time), and nutritional parameters (serum-free medium incubation periods). These parameter adjustments enable reliable tumor treatment while systematically managing preparation complexity.
2Reliability
If stem cells are induced to undergo apoptosis, then cancer cells are effectively treated, but the time required for preparation increases
Solution Approach 1:
The patent applies preliminary action by pre-inducing apoptosis in stem cells under controlled conditions before administering them to patients. Stem cells are pre-treated with apoptosis-inducing agents (staurosporine, thermal stress, or serum starvation) to generate apoptotic bodies that are then ready for immediate therapeutic use, reducing in vivo preparation time while maintaining treatment efficacy against hepatocellular carcinoma and multiple myeloma.
Solution Approach 2:
The patent utilizes periodic action through time-dependent apoptosis induction protocols: serum-free incubation for specific durations (24-72 hours), thermal stress applied in controlled cycles, and chemical agent exposure at defined time points. These periodic treatments optimize apoptotic body generation while managing overall preparation time effectively.
