Improve research ethics by replacing, reducing, and refining the use of animals

Building the future of biomedical research

We pioneered primate in vitro technology that harnesses primate stem cells, primary cells and stem cell-derived cells/tissues, paving the way for enhanced nonclinical drug safety screening in vitro.
