Mr. Hiroya Ishihara is an Application Scientist at Olympus. He was studying the epigenetic factors involved in plant regeneration using omics and microscopy in Tokyo University of Science. Confocal and two-photon microscopy were his trusted partner at that time. Therefore, he joined Olympus to make life science more exciting with microscopes. Currently, he is working on a wide range of projects from basic research to product/sales strategy.

Les organoïdes et les sphéroïdes peuvent reproduire plus fidèlement les conditions rencontrées in vivo, et l’analyse reposant sur l’imagerie permet de suivre les réponses spécifiques des cellules avec une haute résolution spatiale. C’est pourquoi nous avons mis au point des méthodes d’évaluation des effets des médicaments par analyse tridimensionnelle d’images d’organoïdes et de sphéroïdes cancéreux dérivés de patients.

Three-dimensional cell culture models such as patient-derived organoids (PDO) and spheroids have increased in popularity because they can provide a 3D microenvironment that more closely reproduces in vivo conditions compared to 2D monolayer culture. Phenotypic and functional heterogeneity arise among cancer cells within the same tumor because of genetic change, environmental differences and reversible changes in cell properties. Therefore, evaluation of cell-specific responses is important for accurate prediction of drug efficacy and kinetics in vivo.
