CTSG and non-small cell lung carcinoma: Briefly, the human NSCLC cell line PC-9, previously transfected in order to express luciferase, was injected into the tail vein of immunodeficient NSG mice (NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ) in order to establish a relevant orthotopic and bioluminescent NSCLC model in mice.
