In-Vivo Science

In-Vivo Science is a Japan-based life science company that develops and supplies immunodeficient and humanized mouse models used in drug discovery, preclinical testing, regenerative medicine research, and basic medical research. Its core offering centers on NOG mice and next-generation genetically modified NOG-derived strains designed to support human cell engraftment, immune-system reconstitution, antibody evaluation, and disease modeling. The company also provides specialized models such as humanized mice, FcResolv NOG strains, IL-15 and IL-6 transgenic variants, and TK-NOG chimeric liver mice for pharmacology, toxicology, and infection-related studies. Rather than advancing proprietary therapeutics, In-Vivo Science operates as a preclinical platform and research-enabling supplier serving biomedical researchers and drug developers.
