Gene expression comparisons of megakaryocyte-erythrocyte progenitors isolated from wild type and c-MybTG/c-MybTG mice

Transgene insertion in proximity to the c-Myb gene disrupts c-Myb expression in megakaryocyte-erythrocyte progenitors (MEPs), resulting in skewed commitment to megakaryocyte lineage. To understand the genes regulated by c-Myb at the megakaryocyte-erythrocyte bifurcation, MEPs of c-MybTG/c-MybTG mice were examined. Detailed analysis on c-MybTG/c-MybTG is descried in the paper by Mukai et al, Mol Cell Biol 2006. The IL-7R-Lin-Sca-1–c-Kit+ fraction was subdivided into FcR loCD34+, FcRloCD34-, and FcRhiCD34+ populations. Among them, FcRloCD34- fraction was use as MEPs. MEPs from 16 wild type mice and those from 32 c-MybTG/c-MybTG mice were pooled and used for RNA purification.
