Cell membrane integrity after ISAV infection. Microscopic analysis of apoptosis with YO-PRO-1 staining. Cells were mock or ISAV infected, or treated with SS (1 μM 24 h) and stained with YO-PRO-1, Hoechst 33342 and PI, and examined under a fluorescence microscope at the indicated time points (10× magnification).
