v-Myb LZR regulates commitment of common myeloid progenitors.
(A) Colonies of wild-type and ΔP1 v-Myb cells grown in the presence of TGFα, bFGF, and SCF in semisolid medium. (B) Indirect immunofluorescence analysis of representative wild-type and ΔP1 v-Myb cell clones after expansion and differentiation induction by growth factors removal. Double-staining for nuclear antigens (GATA-1 or C/EBPβ, red) and surface antigens (JS4 or MC51/2, green). The bar represents 15 μm.
