Expression of embryonic and adult hemoglobins by an erythroid burst and an erythrocyte-containing mixed colony from the Ly-5.2⁺ cells sorted from BM cells of Ly-5.1 mouse recipients successfully engrafted with the cells cultured from 8.5 dpc Ly-5.2 mouse YS cells on AGM-S3 cells for 6 days.

Lane 1: an erythroid burst. Lane 2: a hematopoietic mixed colony. Lane 3: a granulocyte/macrophage colony. Lane 4: adult BM cells. Lane 5: 8.0 dpc YS cells.
