SAW expanded intercellular space of hBMECs. hBMECs were seeded on round slides for 48 h to firm barrier, then exposed on a 19.68 MHz SAW at 37.8 dBm for 5 min. The slides were subjected to immunofluorescence staining. The distribution of tight junction proteins was hybridized with the corresponding anti-Occludin (A) or anti-ZO-1 (B) antibody. Nuclei was marked with Hochest 33,342 and shown in blue. The representative image of two independent experiments were shown. Scale bar was 10 μm
