Figure 3. Intralesional injection with IL-7 and IL-15 in RFA-treated tumors resulted in the inhibition of lung metastasis of 4T1 mammary tumors.

Figure 3

Balb/c female mice inoculated with 4T1 cells were treated with RFA alone (n=4) or RFA and intralesional IL-7 + IL-15 (n=3) 10 days after tumor inoculation. Control groups remained untreated (n=4). Mice were sacrificed 3−4 weeks after tumor inoculation, and lungs were removed and evaluated for metastasis using a light microscope. Tumors are indicated by arrows.
