Method of Targeting Onolytic Viruses to Tumors

The present invention pertains to a strategy of selectively targeting oncolytic virotherapy, using either naturally occur­ring or genetically modified viruses by packaging them in mesenchymal stem cells (MSCs). The present invention concerns MSCs, compositions comprising the MSCs, and methods of using the MSCs for treatment of cancer and for lysing or inducing apoptosis of cancer cells in vitro or in vivo.Cancer Treatment Lung Cancer, Cell & Tissue Engineering, Respiratory
