Our Team

Hiroyuki Takamatsu, Ph.D., CEO

CEO Message:

"Our clients are extremely satisfied with our contract studies, which were completed successfully by our technicians who are highly skilled in handling of nonhuman primates as well as rodents. In addition to our osteoarthritis, pain, and stroke models, HPR recently developed the photochemically-induced thrombosis (PIT) method to induce vascular cyclic flow reduction, a phenomenon observed in vascular thrombosis and cerebral ischemia. HPR integrated PIT with in vivo imaging technologies, including MRI and PET, to track disease progression in the same subject over time. We are fully committed to supporting your drug discovery efforts with professionalism and our extensive experiences and skill sets."
