Transduction of the green fluorescent protein gene into human DLBCL tumor nodules by JCPyV VLPs in a xenograft mouse model. Human DLBCL–xenografted mice were administered control VLPs or gfp-VLPs intravenously. The DLBCL tumor nodules were frozen-sectioned, and the expression of green fluorescent protein was visualized with a fluorescence microscope.
