In B16F10-IL9+BMDM mice treated with clodronate liposomes, tumors grew in 4 of 7 mice and reached a tumor volume similar to that of the B16F10-Mock and B16F10-Mock+BMDM groups, whereas the control liposome treatment failed to prevent the reduction in tumor volume (Fig. 3H). Here, IL9 is linked to neoplasm.
