Tokyo,
Japan. The cooperative study "Safety Evaluation and Efficacy of Transplantation of Human embryonic stem (ES) Cells in a Monkey Parkinson Disease Model," cosponsored by Tanabe Seiyaku Co., Ltd. (President: Natsuki Hayama) and the Section of
neurology, Department of
internal medicine, Jichi Medical School (Professor: Imaharu Nakano), part of the project on use of human ES cells was examined by the Human Embryo Research Subcommittee of the Bioethics Committee, Council for Science and Technology, the Minister of
education, Culture, Sports, Science and Technology (MEXT), and the project was confirmed as complying with the Ministry's "Guidelines for Derivation and Use of Human
embryonic stem cells."
Having successfully researched the transplantation of cynomolgus monkey ES cells to a monkey model of
Parkinson's disease, Tanabe and Jichi Medical School believe they will be able to contribute to the development of a new therapy for Parkinson's disease by applying these achievements to human ES cells. Tanabe will primarily investigate the induction of differentiation into
nerve cells, and evaluate safety following transplantation in the monkey model. Jichi Medical School will be responsible for transplanting to the monkey model and evaluating the effect. The human ES cells used in the project will be supplied by Cell Therapeutics Scandinavia AB (CTS, Sweden).
Tanabe will then begin its second study using human ES cells, following its cooperative study with
Kyoto University on vascular
regeneration. Tanabe seeks to contribute to the improvement of medical practice by conducting basic studies regarding the potential of new medical technology involving the use of human ES cells, while placing a special emphasis on ethical questions.
