Abstract
In an evaluation method, first, spheroids obtained by three-dimensional culture of multiple kinds of liver-derived cells are imaged by optical coherence photography, a localization region is extracted from the photographic image, the localization region is analyzed (analysis step), and the condition of the spheroid is evaluated. The analysis step includes a first calculation step of calculating the area of the entire spheroid in the photographic image, a second calculation step of calculating the area of the localization region, a third calculation step of calculating the ratio of the localization region on the basis of the two areas, and a fourth calculation step of calculating an evaluation parameter on the basis of the ratio.
