Effects of DON exposure on the ultrastructure of IPEC-J2 cells observed via scanning electron microscopy (n = 3). DON exposure concentrations of (A) 0, (B) 2,000, and (C) 2,500 ng/mL. Red arrows indicate pores, whereas yellow arrows indicate vesicles formed by cell protrusions. 1,500× and 6,000× represent the magnification of electron microscopy
