STAT3 colocalizes with PML but not with PML/RARα in NBs.

293T cells were transfected with STAT3 and G-CSF-R/gp130, together with a mock vector (A-H), PML alone (I-P), or PML + PML/RARα (Q-X). Cells were stained with an anti-PML Ab (A,E,I,M,Q,U), an anti-STAT3 Ab (B,F,J,N,R,V), and DAPI (C,G,K,O,S,W). Original magnifications, ×400.
