  In Japan, stem cell research has seen significant progress through international collaborations, notably with institutions in the United States and Europe. Japanese researchers have been pioneering in the field of induced pluripotent stem cells (iPSCs), with the work of Nobel laureate Shinya Yamanaka laying the foundation for this research. Collaborative efforts have expanded the potential applications of iPSCs in regenerative medicine, disease modeling, and drug discovery. These partnerships have facilitated the sharing of resources and expertise, leading to breakthroughs such as the development of more efficient methods for differentiating stem cells into specific cell types, enhancing their therapeutic potential.
