研究的主要目的是设计一种荧光标记的E-选择素靶向含碘脂质体,进行显微CT的靶向分子成像,同时分析显微CT成像技术与共焦显微技术及活体显微技术等成像技术在细胞分辨率上的相关性。试验细胞为置于培养基中的内皮细胞,实验动物为HT-29荷瘤鼠 The main purpose of the study was to design a fluorescent labeled E-selectin targeting iodine-containing liposomes for targeted molecular imaging of micro CT and to simultaneously analyze micro-CT imaging techniques such as confocal microscopy and in vivo microscopy The relevance of technology in cell resolution. The test cells were endothelial cells placed in culture medium, and the experimental animals were HT-29 tumor-bearing mice
