摘要
Gene therapy is applied into cardiovascular diseases,cancer and diseases that are due to genomic causes.Viral vectors are efficient carriers of genes for transduction,but some problems have become evident.Delivery vectors that are highly potent in terms of gene transduction efficiency should also be safe and easy to apply.Non-viral vectors have recently received focus as gene carriers,but their transduction efficiency is very low and not suitable for in vivo gene delivery.In addition,it is important to develop tissue-specific or selective gene delivery system to avoid side effects in gene therapy.
