Abstract
We have recently established a new bone marrow transplantation (BMT) method in which bone marrow cells are injected into the intrabone marrow (IBM). In the present study, we used an animal model for emphysema (tight-skin [Tsk] mouse) to examine whether IBM-BMT could be used to treat emphysema in Tsk mice. IBM-BMT was carried out from C3H mice into Tsk mice (8-10 weeks old) that had already shown emphysema. Six months after transplantation, the lungs of all the Tsk mice treated with IBM-BMT [C3H-->Tsk] showed similar structures to those of normal mice, whereas the [Tsk-->Tsk] mice showed emphysema, as seen in age-matched Tsk mice. Next, we attempted to transfer emphysema from Tsk mice to C3H mice by IBM-BMT. Six months after IBM-BMT, the [Tsk-->C3H] mice showed emphysema. These results strongly suggest that emphysema in Tsk mice originates from defects of stem cells in the bone marrow.
