Expression of myeloid-specific genes in wild-type and C/EBPβ knockin mice.

Gene expression was measured by RT-PCR using RNA from the bone marrow of wild-type and C/EBPβ knockin mice. After 15 (18S) and 35 (all other genes) cycles, amplification products were gel separated and stained with ethidium bromide. G-CSF R indicates granulocyte-colony stimulating factor receptor; MPO, myeloperoxidase.
