Implication

Preclinical study demonstrates reduced tumor burden and extended survival in ovarian cancer mouse models using mesenchymal cell viral delivery, highlighting targeted virotherapy potential.

Key Points

To assess whether mesenchymal progenitor cells can act as tumor-homing delivery vehicles for conditionally replicative oncolytic adenoviruses to overcome delivery barriers in cancer therapy.
Engineered mesenchymal progenitor cells (MPCs) to carry a genetically modified adenovirus (Ad5/3) designed for coxsackie and adenovirus receptor-independent infection.
Tested in vitro cancer cell killing via co-culture assays and evaluated in vivo tumor homing, tumor burden reduction, and survival outcomes in an ovarian carcinoma mouse model comparing MPC delivery to direct viral injection.
MPCs were efficiently infected by Ad5/3, supported viral replication within the carrier cells, and caused total cell killing when co-cultured with a cancer cell line.
MPC-mediated viral delivery significantly reduced tumor burden on imaging and extended overall survival in tumor-bearing mice compared with direct viral injection.
