Figure 7: IO/HSA-TRAIL accumulated in HCT 116 tumor after i.v. injection, in a chicken embryo model. (A) Tumors treated with IO/HSA control NPs, free TRAIL or IO/HSA-TRAIL NPs were removed from the CAM of the chicken embryos and their NIR fluorescent images taken. (B) The fluorescent intensity of the treated tumors was measured (n=9, mean ± SD).
