Pluripotent Cell Generation via Environmental Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for obtaining pluripotent cells rely on limited tissue sources or the introduction of exogenous reprogramming factors, which are cumbersome and do not effectively convert healthy adult somatic cells into pluripotent states without specific manipulation.
Innovation Solution
Generating pluripotent cells by subjecting differentiated or adult cells to environmental stresses that reduce cytoplasm and/or mitochondria content, such as mechanical stress, chemical exposure, or extreme temperatures, without the need for foreign reprogramming agents, and selecting cells expressing pluripotency markers like Oct4 and Nanog.

1Productivity
If exogenous reprogramming factors are introduced to convert somatic cells to pluripotent state, then pluripotent cells can be generated, but the process becomes cumbersome and requires specific manipulation
Solution Approach 1:
The patent removes the need for exogenous reprogramming factors by extracting only the essential stress elements (ATP treatment, cytoplasmic reduction) that naturally induce pluripotency. This simplifies the reprogramming process from complex genetic manipulation to straightforward physical/chemical stress application.
Solution Approach 2:
The patent enables somatic cells to self-convert to pluripotent state through environmental stress (ATP treatment, cytoplasm removal) without requiring external reprogramming factors. The cell's own machinery responds to stress by activating endogenous pluripotency pathways, making the process autonomous and simpler.
2Ease of manufacture
If healthy adult somatic cells are converted to pluripotent state without reprogramming factors, then the process would be simpler, but there is no direct evidence that this conversion is possible
Solution Approach 1:
The patent converts the harmful effect of environmental stress (which typically damages or kills cells) into a beneficial outcome by using controlled ATP treatment and cytoplasmic reduction to trigger pluripotency. The stress that would normally be detrimental becomes the driving force for successful reprogramming.
Solution Approach 2:
The patent changes key cellular parameters (ATP concentration, cytoplasmic volume, mitochondrial content) to induce pluripotency. By systematically adjusting these parameters, the method provides reliable evidence that somatic cells can be converted to pluripotent state through physical/chemical stress alone.
3Adaptability or versatility
If environmental stress is applied to induce pluripotency, then reprogramming can occur without exogenous factors, but the stress may disrupt cellular membrane of cells
Solution Approach 1:
The patent applies partial cytoplasmic removal (not complete removal) and controlled ATP treatment to induce pluripotency while maintaining cell viability. This partial action approach achieves the necessary stress to trigger reprogramming without excessive damage that would kill the cells or completely disrupt membranes.
Solution Approach 2:
The patent uses brief, intense stress applications (short-term ATP treatment, rapid cytoplasmic reduction) to quickly trigger pluripotency before membrane disruption becomes harmful. By rushing through the stress phase quickly, the method achieves reprogramming while minimizing the duration of harmful membrane disruption.
