Dose-response relationship for Dex induction of Muc-1 expression on S6B45 MM cells. S6B45 MM cells were cultured for 24 hours with Dex (10⁻¹² to 10⁻⁶ mol/L) and analyzed by flow cytometry for Muc-1 expression using VU-4H5, VU-3C6 and isotype control MoAbs. *Cells stained with isotype control. **Cells cultured in media alone and stained with either the VU-4H5 or the VU-3C6 MoAbs. ***Cells cultured with Dex and stained with either the VU-4H5 or the VU-3C6 MoAbs.
