RIKEN BioResource Research Center (BRC^®) Integrative Developmental Engineering Division

Director: Kimiko Inoue (Ph.D.)

Research Summary

To sustain the reliability of the Bioresource Project, it is critically important to continuously maintain and distribute bioresources at a high quality. We develop new techniques for this purpose. The major subjects include those essential for the projects of mouse and cell resources, such as nuclear transfer, assisted fertilization (microinjection), establishment of stem cell lines of various origins, and cryopreservation of embryos/gametes. We also undertake studies on developmental/reproductive biology and epigenetics by using the techniques we develop.
