Cell Selection System for Migratory Subpopulation Isolation

The patent applies preliminary action by pre-selecting and pre-differentiating stem cells in vitro before transplantation. The method involves culturing stem cells under specific conditions to induce differentiation into desired cell types (such as neurons or glial cells) and selecting cells with high migration potential before they are transplanted into the central nervous system. This preliminary preparation ensures that the transplanted cells have the correct phenotype and enhanced ability to migrate to target areas, thereby improving reliability while maintaining therapeutic efficacy.

The patent applies the extraction principle by isolating and selecting specific subpopulations of stem cells that exhibit high migration potential from the total stem cell population. This is achieved through in vitro selection methods that identify and separate cells with enhanced migratory capabilities. By extracting this specific subpopulation, the patent ensures that the transplanted cells have sufficient migration speed to reach degenerated tissue effectively, while the overall cell therapy procedure remains feasible and manageable.

The patent applies local quality by differentiating stem cells into specific cell types (such as neurons, astrocytes, or oligodendrocytes) that are appropriate for the specific type of tissue to be regenerated in the central nervous system. The differentiation process creates cells with localized functional properties and adhesion characteristics suited for their intended target tissue. This ensures that the transplanted cells not only remain in the transplanted area but also perform their specific regenerative functions effectively, thereby improving both retention and regeneration capability.
