Outline of Final Research Achievements |
Lethal radiation of mice before HSC transplantation induces eradication of hematopoietic cells, but its effect on osteogenic cells may be less considered. The mice transferred with RelA-deficient fetal liver cells developed severe osteoporosis, and even the mice transferred with wild type cells reduced trabecular bones, suggesting that lethal radiation may damage to osteogenic cells. In contrast to wound healing M2 type macrophages reducing in bone marrow of the mice transferred with RelA-deficient HSCs, inflammatory M1 type macrophages were aberrantly activated. Co-transplantation of wild type macrophages have recovered osteoporosis which occurs in the mice transferred with RelA-deficient fetal liver cells, indicating that the dysfunction of RelA-deficient macrophages cause the uncoupling of bone metabolism.
