In vitro-cultured 3D structures called organoids have become important tools for biological research, but there is little information concerning simple and efficient methods to evaluate organoid morphology. To address this issue, we attempted to establish a simple method by applying conventional histopathology that enables observation of multiple organoids on a single cross section, maintains good morphology, and is applicable to various histopathological stains. By centrifugation in unsolidified agarose solution, we were able to accumulate the organoids onto a single plane. The morphology was well preserved, and the various morphological types and sizes of organoid structures were identified. This method was also applicable for special staining, immunohistochemistry, and immunofluorescence staining. This method makes it possible to utilize the advantages of conventional pathological methods when studying organoids.
