Bioresource Engineering Division
To support the projects undertaken by the Department of Biological Systems, we develop new techniques for practical genetics, which are essential for consistent, high quality maintenance and supplies of bioresources. The techniques which are to be developed immediately include those related to nuclear transfer, establishment of stem cell lines of various origins, and cryopreservation of embryos/gametes.
- Establishment of methods for cryopreservation of embryos and germ cells
- Establishment of methods for microinsemination (ICSI)
- Establishment of methods for nuclear transfer cloning
- Establishment of new stem cell lines for research use
- March 31, 2009
- Success in doubling of mouse growth through use of an immature embryonic cell, making possible generational change in forty four days, half of the established rate and the shortest rate among vertebrates
- July 17, 2007
- Gene Engineering Division of BRC, in association with Kyoto University, succeeded in the world's first separation and culturing of capsular stem cells which generate sex hormones in the mouse ovary.
- October 08,2010
- Great leap forward
Cells sourced from adult rabbits and recast as stem cells show good potential for laboratory use![]()
