Abstract: Human corneal endothelial cells and/or human corneal endothelial precursor cells are preserved with a high survival rate of these cells being maintained, and the occurrence rate of contaminated cells in post-preservation culturing is suppressed. A storage method of human corneal endothelial cells and/or human corneal endothelial precursor cells is characterized in that human corneal endothelial cells and/or human corneal endothelial precursor cells that have been cultured using a culture medium that contains a ROCK inhibitor, and in which the content of epidermal growth factor (EGF) is less than a concentration that will cause a transformation are harvested at a timing when any one of or a plurality of the conditions (a)˜(d) have been met, and are placed in a suspension state and then preserved.

Abstract: To provide a cell trait assay technique for identifying cultured human corneal endothelium cells of which early clinical effect manifestation and a long-term stable clinical effect are confirmed, in clinical trials. Provided is a method of manufacturing a functional human corneal endothelial cell capable of eliciting a human corneal function when infused into an anterior chamber of a human eye, the method comprising the step of proliferating and/or differentiating or maturing a corneal endothelial progenitor cell under a culture condition capable of minimizing culture stress, such as proliferation stress.

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.
