Abstract

We previously demonstrated in vitro that the simultaneous application of cellular heating and a laser-induced stress wave (LISW) enhanced the uptake of porfimer sodium (Photofrin) by cells. In this study, we attempted to apply this technique to gene transfer to cultured cells. LISW and/or a transient mild (∼43°C) heating been applied to deliver plasmid coding for green fluorescent protein (EGFP) to NIH-3T3 cells. It was found that simultaneous application of an LISW and the heating significantly increased the transfection efficiency by a factor of 2.5 when compared with that for the cells treated with an LISW alone.
