Strain histocompatibility antigens (detected by indirect immunofluorescence reaction) and sex chromosomes were used as markers of donor and recipient cells in monolayer cultures of bone marrow from radiochimeras and from heterotopic transplants. In contrast to macrophages and hemopoietic cells all bone marrow fibroblasts precursors in radiochimeras were of recipient origin; in heterotopic transplants they were of donor origin. These data point to the decisive role of stromal mechanocytes, and not macrophages or hemopoietic cells, in creating the bone marrow hematopoietic microenvironment.

D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D011828 Radiation Chimera An organism whose body contains cell populations of different genotypes as a result of the TRANSPLANTATION of donor cells after sufficient ionizing radiation to destroy the mature recipient's cells which would otherwise reject the donor cells. Chimera, Radiation,Chimeras, Radiation,Radiation Chimeras
D001853 Bone Marrow The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

D003602 Cytotoxicity, Immunologic The phenomenon of target cell destruction by immunologically active effector cells. It may be brought about directly by sensitized T-lymphocytes or by lymphoid or myeloid "killer" cells, or it may be mediated by cytotoxic antibody, cytotoxic factor released by lymphoid cells, or complement.
