Takashi Tsuji, Ph.D., is the Team Leader of the Laboratory for Organ Regeneration at Riken BDR. His research focuses on understanding epithelial-mesenchymal interactions during organogenesis and utilizing this knowledge to develop regenerative technologies. By creating regenerative primordia for teeth, hair follicles, and endocrine tissues through the control of stem cells, he has demonstrated successful integration with surrounding tissue upon transplantation into mice. Using pluripotent stem cells, such as embryonic stem cells and induced pluripotent stem cells, his team aims to replicate organogenetic fields observed in early embryos to drive the formation of functional tissue structures, contributing to regenerative medicine applications like tooth and hair follicle regeneration.
