Recently, there is a growing need for human biospecimens in the fi eld of life science research. Therefore, many biobanks that collect and provide human specimens have been established worldwide. In Japan, several universities and hospitals have their own biobanks, but they are not being used much because of inadequate ethical guidelines and legal regulations. The Tsukuba Human Tissue Biobank Center (THB) was established in 2013 to provide a variety of tumor samples and their clinical data. It have been already collected a large number of specimens obtained from more than 2,000 patients. As a fi rst step, we could build the infrastructure for the biobank, and sample providing was started. Our next plan is to collaborate with other hospitals in the surrounding area. We hope the bionbank network support basis of research toward the achievement of regenerative medicine is build in the future.
