| abstract |
A method of treating a tumor in an animal by administering to the animal mesenchymal stem cells that have been contacted with a stimulating, or activating agent, such as TNF-a, that stimulates the mesenchymal stem cells to express increased amounts of at least one agent, such as TRAIL and/or DKK-3, that inhibits, prevents, or destroys the growth of tumors. The stimulated, or activated mesenchymal stem cells may be administered in combination with at least one chemotherapeutic agent, such as doxorubicin. |
