To perform proof-of principle in vivo study, NCI-N87-Vector or NCI-N87-HOXA11 cells mixed with HMrSV5 cells were transplanted into peritoneal cavity of BALB/c mice (Fig. 4A), cells stably expressed luciferase and peritoneal dissemination of tumor were observed by an in vivo imaging system (IVIS) after four weeks. Here, HOXA11 is linked to neoplasm.
