title: Selective advantage of normal erythrocyte production after bone marrow transplantation of alpha-thalassemic mice.
abstract: Anemia resulting from alpha-thalassemia in mice was corrected by transplantation of normal bone marrow cells following sublethal total body irradiation, resulting in partial hematopoietic chimerism with a preponderance of normal peripheral blood red cells. Peripheral blood red cell chimerism in recipients of graded numbers of bone marrow cells from sex-mismatched donors, determined by cytometric analysis, was directly compared with immature hematopoietic cell (CFU-S) chimerism and peripheral blood white cell chimerism. The latter two were assessed by fluorescent in situ hybridization with a murine Y-chromosome-specific probe. Peripheral blood white cell chimerism consistently corresponded with immature hematopoietic cell chimerism, emphasizing the selective advantage of normal red cell production in partially chimeric alpha-thalassemic mice.
