| Description: |
Confocal microscopy of various healthy tissues isolated from immunocompetent mice and ovarian tumor lesions. Epithelial cell adhesion molecule (EpCAM) is expressed in non-pathological tissue as well as malignant lesions, where ovarian tumor lesions expressed more moderate and heterogeneous levels of EpCAM. Polymeric nanoparticles encoding a murine version of the EpCAM × CD3 bispecific antibody were employed in this study to achieve high gene transfer into circulating myeloid cells, which subsequently secrete Bispecific T-Cell Engagers (BiTEs) and effectively concentrate this drug at tumor sites.
