Cytotheryx, Inc. is a biomedical research company focused on the development of a consistent, high-quality source of primary human hepatocytes or liver cells and the use of those cells for research and clinical applications. Primary human hepatocytes are currently used in toxicology studies, hepatitis research, and transplants, but the limited supply restricts broader applications. Our foundational science will enable applications in liver assist devices, cell and gene therapy, drug delivery, and allotransplantation.
