陈诗书、钱关祥两位教授带领上海第二医科大学人类基因治疗研究中心科研人员成功制备了治疗肝癌和胃癌的基因工程“瘤苗”。所谓“瘤苗”(肿瘤疫苗),即先制备恶性肿瘤治疗所需的细胞因子基因cDNA,将其克隆至安全的逆转录病毒载体,并包装成重组的缺陷型逆转录病毒颗粒,用以感染肿瘤细 Professors Chen Shishu and Qian Guanxiang led the researchers at the Second Human Medical Research Center of Shanghai Second Medical University to successfully prepare genetic engineering “tumor vaccines” for the treatment of liver cancer and gastric cancer. The so-called “tumor vaccine” (tumor vaccine), which is to prepare the cDNA of the cytokine gene required for the treatment of malignant tumors, clone it into a safe retrovirus vector, and package it into recombinant defective retrovirus particles for infection.
