 Personal iPS

Background and History

Human induced pluripotent stem cells (iPSCs) were first established in 2007 by Professor Shinya Yamanaka at Kyoto University. These "pluripotent cells", can differentiate into various tissue types, and can be created from adult donor biospecimens. Regenerative therapies using iPSCs have the potential to provide novel treatments for patients globally, and they are currently being used for regenerative medicine research worldwide.

According to estimates by the Japanese Ministry of Economy, Trade and Industry1 the global market for regenerative medicine will grow to an estimated value of 17 trillion yen in 2030 and 53 trillion yen in 2050. Japan is poised to become a world leader in the field following the enforcement of "The Act on the Safety of Regenerative Medicine" and the " Revised Pharmaceutical Affairs Law" on November 25 2014.


Regenerative medicine using human iPSCs, which were discovered in Japan, is now gaining attention overseas. Clinical research at Japanese medical institutions could lead to novel medical treatments for patients in Japan and abroad where there is currently an urgent clinical need. To respond to this growing demand, REPROCELL and JTB have established a partnership to provide "Personal iPS" overseas. Using JTB's knowledge as a medical coordinator, this collaboration will increase regenerative medicine technologies using Japanese iPSCs and revitalize Japan’s medical infrastructure.

Personal iPS

Personal iPS is a novel service that uses Japan's exclusive technology for generating iPSCs from urine and teeth. These patient-specific iPSCs are cryopreserved and prepared for future disease treatments. The demand for this service indicates that regenerative treatments will be possible in the near future, including individually tailored, next-generation treatments that do not depend on donors. Currently, research using iPSCs is progressing globally, and the need for these cells is expanding the field of regenerative medicine.

About REPROCELL, Inc.: REPROCELL was established in 2003 as a spin-out from Kyoto University and the University of Tokyo. Since then, the company has been engaged in research and development using ES cells, the basis of iPSC research. Due to our technologies and expertise in this field, we have worked with 90% of the world's top 30 pharmaceutical companies. REPROCELL has received “right to use” patents from Kyoto University and the University of Tokyo for its iPSC culture technologies, which RE used by most of the clinical research facilities and medical institutions in Japan. The company’s culture medium – which was developed using technology to produce high-quality, clinically-applicable iPSCs – was used by Professor Yamanaka in his experiments to establish the world's first human iPSCs. Following this, REPROCELL successfully commercialized the world's first human iPSC-derived cardiomyocytes and is now a leading company in iPSC research.
