Ultrasound-mediated destruction of microbubbles has been proposed as an innovative non-invasive drug delivery system for cancer therapy. We developed a specific drug delivery system for squamous cell carcinoma that uses sonoporation with the anti-epidermal growth factor receptor (EGFR) antibody. Administration of a low dose of bleomycin (BLM) by sonoporation with the anti-EGFR antibody produced a marked growth inhibition of Ca9-22 cells in vitro. In addition, scanning electron microscopic analysis revealed apparent surface deformation of Ca9-22 cells treated with sonoporation in the presence of the antibody. Interestingly, the population of apoptotic cells was remarkably increased when a low dose of BLM was delivered using sonoporation with the Fab fragment of the anti-EGFR antibody. These findings indicate that sonoporation with the Fab fragment makes it possible to administer drugs into cells more efficiently and specifically, suggesting a novel application for chemotherapy and gene therapy treatments for oral squamous cell carcinoma.
