Outline of Final Research Achievements |
We analyzed the long-term tumor-homing effect of allogeneic mouse MSCs (mMSCs) and explored the anti-tumor effect and drug delivery function using IFN-Beta-mMSCs. The IVIS revealed the accumulation of fluorescence was observed in the tumor both in vivo and after excision. Immunohistochemistry using anti-GFP antibody revealed that the mMSCs existed within the tumor until 14 days. The ELISA showed increased concentrations of IFN-β only in the tumors, with the values gradually diminishing over 14 days. The mMSCs-IFN-β group survived significantly longer than the control group, while the mMSCs-alone group did not show a survival advantage. In conclusion, allogeneic mMSCs showed a homing ability for mouse neuroblastoma and existed within the tumor for as long as two weeks. This may be a candidate drug delivery vehicles for antitumor agents against neuroblastoma.
