Reversal by DN-GATA of the effect of aNotch1 on the granulocytic differentiation in 32D cells.

Activated Notch1-expressing 32D cells were infected with a mock virus or a DN-GATA–containing pMX/IRES-EGFPpuro virus. The cells are shown stained with Wright-Giemsa stain 4 days after the addition of G-CSF. Original magnification × 400. Three independent DN-GATA–expressing clones and control clones derived from 2 independent aNotch1-expressing clones were investigated.
