Fig. 3.
Globin gene expression in single erythrocyte-containing colonies.
(A) Colonies formed by hGM-CSF from E12.5 FL cells of hGMR-expressing EPOR+/+ embryos (lanes 1 to 4) and EPOR−/−embryos (lanes 5 to 8). (B) Colonies formed by hGM-CSF from E8.0 YS cells of hGMR-expressing EPOR+/+ embryos. (C) Globin gene expression of a granulocyte-macrophage colony formed by hGM-CSF from E12.5 FL cells of hGMR-expressing EPOR+/+ embryos as a negative control (lane 1), adult bone marrow cells (lane 2), E12.5 FL cells (lane 3), and E9.5 YS cells of hGMR-expressing mice (lane 4).
