Morphology and function of human tissues were well maintained in the improved severe combined immunodeficient (SCID) mice for long period (2 to 3 years). Cs-137 ray exposure to transplant human thyroid tissues resulted in the disappearance of the follicles, significant decrease of human thyroid hormones, an increase of mutations, and change of gene expression, while low dose rate radiation exposure rarely induced these defects. Change of gene expression was also induced in extremely high incidence by fission neutron., 資料番号: AA0046917024}, pages = {72--73}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {ヒト組織置換SCIDマウスを用いた宇宙放射線影響評価システムの開発}, year = {2004} }
