CEO Message

ReproCELL is going to continue challenging the new horizon of the ES/iPS cell business as a pioneering company

ReproCELL is a biotech company that was established in 2003 on the basis of technologies developed by Professor Nakatsuji (who had established the first human ES cells in Japan in that year) at Kyoto University and Professor Nakauchi at Tokyo University. The first human ES cells were established at Wisconsin University in 1998, and the first human iPS cells were established at Kyoto University in 2007. Human ES/iPS cell research is still in its early stages, but it is expected to lead to the next generation of life science businesses such as regenerative medicine, tailor-made medicine, and drug development support.

ReproCELL has been playing a pivotal and pioneering role in the ES/iPS cell business by starting to commercialize culture media for human ES/iPS cells in 2005, the world’s first cardiomyocytes derived from human iPS cells in 2009, and the world’s first neurons derived from human iPS cells in 2010. We will continue expanding our business in the field, including the development of culture reagents, stem cell-based drug development support technologies, and tailor-made medicine.

ReproCELL’s company policies are “customer centeredness,” “faith and trust,” and “a frontier spirit.” We believe that the company can exist only by providing value to customers and contributing to society. Toward this purpose, ReproCELL places emphasis on faithfully and bravely taking up new challenges. Through our business, we will contribute to the health and happiness of people worldwide.
