Liposome-based drug delivery systems hold great potential for cancer therapy. However, to enhance the localization of payloads, an efficient method of systemic delivery of liposomes to tumor tissues is required. In this study, we developed cationic liposomes composed of polyethylenimine (PEI)-conjugated distearoylglycerophosphoethanolamine (DSPE) as an enhanced local drug delivery system. The particle size of DSPE-PEI liposomes was 130 ± 10 nm and the zeta potential of liposomes was increased from -25 to 30 mV by the incorporation of cationic PEI onto the liposomal membrane. Intracellular uptake of DSPE-PEI liposomes by tumor cells was 14-fold higher than that of DSPE liposomes. After intratumoral injection of liposomes into tumor-bearing mice, DSPE-PEI liposomes showed higher and sustained localization in tumor tissue compared to DSPE liposomes. Taken together, our findings suggest that DSPE-PEI liposomes have the potential to be used as effective drug carriers for enhanced intracellular uptake and localization of anticancer drugs in tumor tissue through intratumoral injection.宝鸡pg电子娱乐游戏app 生物技术供应相关成品：DSPE-PEG-αCD20mAb（二硬脂酰基磷脂酰乙酸乙酯胺-聚乙二醇-*靶点球蛋白)DSPE-PEG-RaltitrexedDPPE-PEG-MalCy3-DSPEDSPE-PEG-ANTPCGPYTHDCPVKR（二硬脂酰基磷脂酰无水乙醇胺-聚乙二醇-*靶向药物蛋白酶)DSPE-PEG-lactosylDOPE-PEG-CH2COOH以下稿件內容来源于种类杂志或论文，如遇图片侵权请联系起来让我们移除！
