Effect of immobilized Deltaext-myc on differentiation of monocytes cultured with GM-CSF.
Phase contrast microscopy of cells derived from monocytes cultured for 6 days with GM-CSF and 1 μg/mL Deltaext-myc (A), GM-CSF and control medium (B), or GM-CSF and IL-4 (C). Tissue culture wells were coated with anti-myc antibody, 9E10 F(ab′)2, to attach myc-containing Deltaext-myc to the plastic surface (original magnification × 200).
