IL11 and neoplasm: A xenograft model of chemokine‐producing transgenic mouse‐derived clones and parental clones was applied in a study by Marusyk et al.43 In terms of the variability between the groups in morphology, proliferation, and vascularization, only chemokine (C‐C motif) ligand 5 (CCL5)‐ and interleukin 11 (IL‐11)‐overexpressing subclones were able to enhance tumor growth.
