  • Publication number: 20230214998
    Abstract: A cell evaluation method evaluates the quality of a cell population including a plurality of cells. The cell evaluation method comprises: an index calculation step of calculating an index, based on a captured image of the cell population, the index including at least any one of an average distance representing a packing degree of the cells, a spring constant representing a degree of consistency in distances between the cells, and a hexagonal order parameter representing a degree to which an arrangement of the cells resembles a regular hexagon; and an evaluation step of evaluating the cell population, based on the index calculated in the index calculation step.

  • Patent number: 11384334
    Abstract: Provided are: a polymer gel for a medium, and a medium in which the stiffness of the polymer gel can be easily and reversibly changed and the shape of cells can be controlled according to the stiffness of the gel; and a method for culturing cells using the medium. The polymer gel for a medium contains a solvent and a crosslinked structure that is crosslinked by reversible bonds. The stiffness of the polymer gel for a medium can be easily and reversibly changed. Accordingly, when the polymer gel for a medium according to the present invention is used, cell morphology and function can be reversibly controlled according to the stiffness of the gel.
