USF1 overexpression prevents trophoblast cell fusion and differentiation. Freshly isolated cytotropholast cells were cultured on coverslips and infected with different amounts of recombinant adenovirus expressing either USF1 (MOI = 5 or 10) or β-Gal (MOI = 10). After 72 h, the cells on the coverslips were stained with hematoxylin and eosin. Magnification, ×200.
