The History of REPROCELL

Established in 2003 by preeminent Japanese university researchers, REPROCELL quickly became the leading stem cell research company in Japan. Soon thereafter, REPROCELL products were employed by Professor Shinya Yamanaka during his pioneering research on iPSC technologies at Kyoto University.  We were the first company to offer iPSC-derived human cardiomyocytes, hepatocytes, and neuronal cells for research applications and were listed on the Japan JASDAQ / Growth stock market in 2013.

In recent years,  REPROCELL has expanded through a series of acquisitions. This expansion has created a workflow - including human tissue acquisition (BioServe®), RNA reprogramming (Stemgent®), 3D technologies (Reinnervate®), and drug discovery (Biopta®) - in addition to our core capabilities. These acquisitions have been consolidated to regional offices, and the names converted to daughter brands. In the stem cell and drug discovery “market- space”, no other company has such a broad combination of expertise that can be applied to drug discovery and regenerative medicine.
