Recent technological advances have set the stage for a renewed focus on human-based solutions called new approach methodologies (NAMs) that can complement, and in some cases replace, animal models in research and regulatory testing. These NAMs generally span advanced cell-tissue-organoid (in vitro), computational modeling (in silico), and cell-free biochemical analysis (in chemico) techniques, with [...]
