ECoM-G and ECoM-M clones exhibit lineage- and differentiation-specific patterns of gene expression.

Northern blot analysis of myeloid genes was performed on total RNA samples from ECoM-G and ECoM-M clones cultured in the presence (E2) or in the absence of estrogen for the indicated number of days. RNA from NIH3T3 fibroblasts was used as a nonmyeloid control. Names of the probes are indicated to the left of each blot. Equivalent loading was verified by hybridization of a β-actin probe.
