Abstract Objective: To get the αvβ3 receptor combination information of the different tumor cells with RGD peptide by vivo and vitro method, so as to guide clinical molecular imaging research. Materials and Methods: Comparison combination specification of the pancreas tumor cell, hepatic tumor cell, intestine tumor cell and cervix tumor cell with FITC-HYNIC-RGD, and acquisition data for the xenograft mice model of breast tumor and hepatic tumor cell after IV injection of 99mTc-HYNIC-RGD. Results: Combination number of the pancreas tumor cell, hepatic tumor cell is higher than intestine tumor cell and cervix tumor cell with FITC-HYNIC-RGD. The uptake of breast tumor cell with 99mTc-HYNIC-RGD is 40% higher than that of hepatic tumor cell after injection. Conclusion: Combination of the pancreas tumor cell, hepatic tumor cell with FITC-HYNIC-RGD is the highest. Uptake of breast tumor with xenograft mice model is higher than hepatic tumor after injection of 99mTc-HYNIC-RGD.
